The five senses of the body include sight, hearing, taste, smell, and touch. Human beings and most other animals use the five senses to help them live and experience the world around them. The senses also help people to learn, protect themselves, and to enjoy the differences between foods, sounds, and other experiences a person has in life. The senses also work together to give you a clear picture of the activities around you.

The first sense is sight, which depends on the eyes. People use their eyes to see the people, objects, and other items around them. Of course, the sense of sight is also helpful for reading, traveling, driving, and moving from place to place each day. Inside the eye there are special lenses that take in light to help people see things. If it is too dark, a person will have trouble seeing. The eyes can also adjust to the amount of light available. Many people, though, young and old, may also need glasses to help them see clearly. Some people may be able to see things up close, but not far away, which means they are nearsighted. If a person can see far away but not up close, they are farsighted. If a person is blind, there are special books written in braille which helps them feel the raised letters. Some blind people also have special dogs to help guide them from place to place in their home and when they go places.

The second sense, hearing, depends on the ears. There are actually three parts of the ear, the outer ear, middle ear, and the inner ear. The outer ear is the part other people can see. The outer ear catches the sound waves as they travel to the person and then sends them into the ear. The outer ear acts like a funnel collecting the different sounds a person experiences. The middle ear contains the eardrum and several bones which transfers sound from the outer ear to the inner ear. The inner ear consists of tubes and passages that takes the sound vibrations and sends themto your brain for understanding. [A]

The third sense, smell, depends on your nose. Inside the nose there is a substance that takes the fumes of an odor and then sends it to the brain. If a person gets a cold the sense of smell may not be as strong. The nose also helps clean the air a person breathes by filteringit. Inside the nose there are tiny hairs, called cilia, which act as cleaners to help keep substances in the air from entering a person's body through the nose. In addition, the nose affects the way a person speaks. If a person holds their nose while speaking, their voice will sound different. Smell also helps with the sense of taste. As a person tastes the food in their mouth, the aroma of the food enters a person's nose. [B]

The next sense, feeling, or touch, can be experienced throughout the entire body through a person's skin. Some parts of the body are more sensitive to touch than other parts. The skin has parts in it that collect information and sends it the brain. Most of a person's feeling is done by the hands. In addition, when a person has a stomach ache or feel other kinds of pain, the sense of touch is working from inside the body. [C]

The final sense, taste, comes from the taste buds on a person's tongue. As stated earlier, the sense of smell also affects the sense of taste. The tongue tastes four different flavors: salty, sweet, sour, and bitter. Many foods a person eats may be a combination of the four main flavors. The tongue can also feel whether something in a person's mouth is hot, cold, creamy, crunchy, or dry.

In summary, the five senses are sight, hearing, smell, feeling, and taste. [D]

The Human Heart

The human heart is an amazing organ of the human body. The heart is an organ which pumps life-giving blood throughout the body. It works together with blood and blood vessels to supply all of the needs of the cells.

The heart is located in the middle of the chest and slightly to the left. It is divided into two halves and has two hollow spaces or chambers. The blood enters the atria, which is the upper chamber and is then pumped to the ventricles, two lower chambers. Blood from the ventricles goes to the lungs and to every cell in the body. [A]

An artery is a blood vessel which carries blood away from the heart. A main artery may be as thick as a thumb. Blood is made up of red cells, white cells and platelets floating in a fluid called plasma. Plasma is a liquid and can easily pass through small blood vessels into cells and makes up over one-half of the blood. The plasma carries nutrients (food) from the stomach to be used as fuel for energy. Plasma also helps keep the body warm.

The blood then returns to the heart through blood vessels called veins. The veins on the skin, may look blue, especially on the hands and arms. The walls of a vein are much thinner than those of an artery. Two large veins bring the blood back to the heart. One comes from the brain and the chest. The other comes from the stomach and lower body. [B]

Blood doesn't flow at the same speed through all of the body. As it gets farther away from the heart, it slows down. It goes slowly when the red blood cells carrying the food and oxygen squeezethrough into the cells. [C]

The heart beats or pumps every second of the day or night. It beats or pumps 100,000 times a day, every day of a person's life. Every time a heart beats or pumps out a stream of blood, this beat, called a pulse, can be felt on the inside of the wrist. The pulse rate in an adult is between sixty and one hundred beats per minute. Children's pulse rates range from ninety to one hundred twenty beats per minute. [D]

In summary, the circulatory system which includes the heart, blood vessels and blood, work together to supply the cells with all the food and oxygen a body needs to maintain life. Blood is made up of red cells, white cells and platelets floating in a fluid called plasma. Arteries carry blood away from the heart, and veins carry the blood back to the heart. The heart beats thousands of times a day, every day. It beats much faster in children. The human heart is an amazing organ which is part of a system of many veins, arteries, and vessels which moves blood throughout the body keeping humans alive.

Patient zero is generally taken to mean the first case in a disease outbreak – but the term is often applied in different ways. When it comes to zoonotic diseases (ones that jump from animals to humans, like SARS-CoV-2), patient zero might refer to the first-ever human case – the point at which the virus spills over from an animal to a human. For the general public, however, patient zero is often used to refer to the first case in a particular region, or the first case that's come to the attention of health authorities. However, these are not always the same thing. Sometimes the first case that's notified to us is not the first case in an outbreak. Similarly, just because someone is identified as the first case doesn't mean they spread the disease to anyone else, or behaved irresponsibly – with something like coronavirus, they may not even know they're sick.

This is part of the reason why patient zero is not a term epidemiologists or public health experts tend to use - it's not specific enough. They prefer the term index case to refer to the first person officials became aware of in an outbreak (which gives them a clue something's going on), and primary case to refer to the person who introduces a disease into a new population - a community, country or the world. Sometimes, the primary case and the index case will be the same person, but not always. For many outbreaks - such as HIV/AIDS, and possibly COVID-19 – we will never know the primary case.

While the use of the term patient zero can be fraught, tracing outbreaks back to their beginnings remains important in public health. In the early days of an outbreak, it's still possible to catch embers of disease before they become full-blown fires. "You can actually stamp them out, by identifying every case, tracking every contact, quarantining them, making sure there's no further spread," Professor Raina Macintyre, head of biosecurity at UNSW's Kirby Institute says. But even after those critical first days or weeks, tracing cases back to patient zero can still give both health experts and relevant authorities for insights into how disease spreads and understands the role that health services and adequate sanitation systems play in controlling the spread of the disease. That's the purpose of trying to understand an index case or a first case – to establish the opportunity to learn from the breakout and try to make sure it doesn't happen again.

Patient zero is generally taken to mean the first case in a disease outbreak – but the term is often applied in different ways. When it comes to zoonotic diseases (ones that jump from animals to humans, like SARS-CoV-2), patient zero might refer to the first-ever human case – the point at which the virus spills over from an animal to a human. For the general public, however, patient zero is often used to refer to the first case in a particular region, or the first case that's come to the attention of health authorities. However, these are not always the same thing. Sometimes the first case that's notified to us is not the first case in an outbreak. Similarly, just because someone is identified as the first case doesn't mean they spread the disease to anyone else, or behaved irresponsibly – with something like coronavirus, they may not even know they're sick.

According to the passage which statement is true about SARS-CoV-2?

Read the message and choose the best answer.

Antioxidants are substances - artificial or natural - that prevent and slow cell and tissue damage by attacking free radicals, which are molecules that have an unpaired electron. Free radicals are natural byproducts of our metabolism and are also generated in response to environmental stressors, such as exposure to pollution, X-rays or cigarette smoke. In high quantities, free radicals can cause oxidative stress, which is when the body has too many free radicals that start to destroy DNA, fatty tissue and proteins. [A]

Unlike free radicals, antioxidants have extra electrons. This means that they can pass their surplus electrons to free radicals, stabilizing the free radicals so they can no longer damage the body's cells and tissues. In doing so, antioxidants ward off or slow oxidative stress, preventing serious illnesses. Oxidative stress has been linked with illnesses such as cancer, heart disease and some neurodegenerative diseases, including Alzheimer's and Parkinson's disease. The best way to increase antioxidants in the body and maintain a healthy balance of free radicals is to incorporate antioxidant-rich foods into your diet. [B]

The term “antioxidant” is often used to describe different foods, but it more accurately describes chemical property. Any substance that can strip free radicals of their damaging properties is considered an antioxidant. Researchers have discovered hundreds of substances that fit the antioxidant description, and there are perhaps thousands more. Vitamin C and vitamin E are two of the most common antioxidants found in food. In addition to fighting free radicals, vitamin C supports the immune system and helps repair bones, teeth and cartilage. Vitamin E is a powerful tool in maintaining eye health, producing hormones that regulate blood pressure and repairing muscles after exercise. Carotenoids- a class of compounds found in fruits and vegetables that are red, orange and yellow - are also well-known antioxidants.

Antioxidant carotenoids include beta-carotene, lycopene, lutein and zeaxanthin. However, taking high doses of some carotenoid supplements, such as beta-carotene. Can increase health risks, such as an increased chance of lung cancer in smokers. [C]

Antioxidants are most often in fruits, vegetables and legumes, although they can be found in almost every food group. Fruits contains essential nutrients such as potassium, fibre and folate - nutrients that help maintain blood pressure, lower cholesterol and repair body tissues. Blueberries, cranberries, apples, strawberries and more are all filled with antioxidants. Dried fruits - although often high in processed sugars - have a higher antioxidant ratio than fresh fruits, since they lose mass from water. They act as quick antioxidant fuel due to their high concentration of antioxidants. Carotenoids are found in red, orange or yellow vegetables. Many green vegetables such as kale, broccoli and spinach are excellent sources of antioxidants, namely quercetin and lutein. [D]

Antioxidants are substances - artificial or natural - that prevent and slow cell and tissue damage by attacking free radicals, which are molecules that have an unpaired electron. Free radicals are natural byproducts of our metabolism and are also generated in response to environmental stressors, such as exposure to pollution, X-rays or cigarette smoke. In high quantities, free radicals can cause oxidative stress, which is when the body has too many free radicals that start to destroy DNA, fatty tissue and proteins. [A]

Unlike free radicals, antioxidants have extra electrons. This means that they can pass their surplus electrons to free radicals, stabilizing the free radicals so they can no longer damage the body's cells and tissues. In doing so, antioxidants ward off or slow oxidative stress, preventing serious illnesses. Oxidative stress has been linked with illnesses such as cancer, heart disease and some neurodegenerative diseases, including Alzheimer's and Parkinson's disease. The best way to increase antioxidants in the body and maintain a healthy balance of free radicals is to incorporate antioxidant-rich foods into your diet. [B]

The term “antioxidant” is often used to describe different foods, but it more accurately describes chemical property. Any substance that can strip free radicals of their damaging properties is considered an antioxidant. Researchers have discovered hundreds of substances that fit the antioxidant description, and there are perhaps thousands more. Vitamin C and vitamin E are two of the most common antioxidants found in food. In addition to fighting free radicals, vitamin C supports the immune system and helps repair bones, teeth and cartilage. Vitamin E is a powerful tool in maintaining eye health, producing hormones that regulate blood pressure and repairing muscles after exercise. Carotenoids- a class of compounds found in fruits and vegetables that are red, orange and yellow - are also well-known antioxidants.

Antioxidant carotenoids include beta-carotene, lycopene, lutein and zeaxanthin. However, taking high doses of some carotenoid supplements, such as beta-carotene. Can increase health risks, such as an increased chance of lung cancer in smokers. [C]

Antioxidants are most often in fruits, vegetables and legumes, although they can be found in almost every food group. Fruits contains essential nutrients such as potassium, fibre and folate - nutrients that help maintain blood pressure, lower cholesterol and repair body tissues. Blueberries, cranberries, apples, strawberries and more are all filled with antioxidants. Dried fruits - although often high in processed sugars - have a higher antioxidant ratio than fresh fruits, since they lose mass from water. They act as quick antioxidant fuel due to their high concentration of antioxidants. Carotenoids are found in red, orange or yellow vegetables. Many green vegetables such as kale, broccoli and spinach are excellent sources of antioxidants, namely quercetin and lutein. [D]

Communication in general is process of sending and receiving messages that enables humans to share knowledge, attitudes, and skills. Although we usually identify communication with speech, communication is composed of two dimensions - verbal and nonverbal. Nonverbal communication has been defined as communication without words. It includes apparent behaviors such as facial expressions, eyes, touching, tone of voice, as well as less obvious messages such as dress, posture and spatial distance between two or more people. Activity or inactivity, words or silence all have message value: they influence others and these others, in turn, respond to these communications and thus they are communicating. Commonly, nonverbal communication is learned shortly after birth and practiced and refined throughout a person's lifetime. Children first learn nonverbal expressions by watching and imitating, much as they learn verbal skills. Young children know far more than they can verbalize and are generally more adept at readingnonverbal cues than adults are because of their limited verbal skills and their recent reliance on the nonverbal to communicate. As children develop verbal skills, nonverbal channels of communication do not cease to exist although become entwined in the total communication process.

Traditions, saying, beliefs, language, and values are just a few things that make up our culture. Culture is the framework in which families are structured. It shapes our expectations and ideals. Culture plays a part in the meaning of marriage and our roles as husbands, wives, children and parents. Understanding cultural differences and similarities related to marriage is important. Culture affects the roles that spouses take within marriages, the age at marriage and number of children a couple have, the meaning of divorce, cohabitation and non-marital childbearing, and the way parents raise children. Understanding how relationships and marriages vary across cultural contexts, and how they are similar, we will be able to identify the unique ways that marriages and family life affect people of various cultures. As a result, we will be able to help families and sustain happy marriages. A cross cultural marriage or similar love relationship can be extremely exciting. The cultural background, visits to the other country, the language of the country and learning to speak it, the different habits and ways of doing and saying things that people from other cultures have, are all very exciting indeed. What of the disadvantages of a cross cultural marriage or love relationship with someone from another country or cultural background? No matter how much you love your husband or wife, no matter how high your level of cross cultural awareness, cross cultural communication and respect for differences. Misunderstanding seems to be unavoidable.
