How do virus cause disease

Answers

Answer 1

Answer:

Viruses make us sick by killing cells or disrupting cell function. Our bodies often respond with fever (heat inactivates many viruses), the secretion of a chemical called interferon (which blocks viruses from reproducing), or by marshaling the immune system's antibodies and other cells to target the invader.

Answer 2

Answer:

Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves. This can kill, damage, or change the cells and make you sick. Different viruses attack certain cells in your body such as your liver, respiratory system, or blood.

Viruses infect a host by introducing their genetic material into the cells and hijacking the cell's internal machinery to make more virus particles. With an active viral infection, a virus makes copies of itself and bursts the host cell (killing it) to set the newly-formed virus particles free.

Explanation:

Every virus-host relationship is different. In most cases, viruses do not cause any disease, and many are beneficial. For example, in mice a herpes virus prevents infection from the plague bacteria.

Although many viruses or bacteria are extremely helpful and we wouldn't be here without them, some live in our bodies and help us process and digest different foods, and without them we wouldn't be able to do that, we call these beneficial or symbiotic bacteria and viruses.

O The villagers are exposed to a great deal of air pollution from urban traffic.
The villagers are exposed to a great deal of air pollution from fuels used for cooking.
O The villagers are allergic to your body spray.
O Many of the villagers have had malaria, and lung damage is a permanent effect of the
disease.

Answers

Answer:

Many of the villagers have had malaria, and lung damage is a permanent effect of the  disease.

Explanation:

In a small village in Haiti, a high number of villagers suffer from respiratory problems. This is because many of the villagers have had malaria, and lung damage is a permanent effect of the disease.

What are respiratory problems?

This is related to the lungs and occurs when a person does not get enough oxygen to breathe or has pulmonary inflammation. The small village in Haiti has little industry and is located far from the industrial sectors. So it is assumed to be cleaner air.

These villagers can't get access to proper sanitation and medication as the village is small and not properly developed. So in such a condition, there is a high chance of spreading malaria. Most of them are suffering from malaria, which causes respiratory problems.

Hence, a high number of villagers suffer from respiratory problems. This is because many of the villagers have had malaria, and lung damage is a permanent effect of the disease.

3. Michelangelo discovered the four chambers of the heart, the workings of the aortic valve, and how the cone shape of the heart assists in its functions.

true or false ​

Answers

The answer to the true or false is false

The correct answer is - false as William Harvey discovered that the heart has four chambers which are believed to be influenced by the work of Leonardo Da Vinci.

It is believed that artists like Michelangelo and Leonardo Da Vinci had a very good interest in human anatomy and heart, however, there is not enough evidence that Michelangelo provided anything in respect of the human heart or its chamber.

It is believed that Leonardo found that there are four chambers in the human heart and that currents in the blood flow, formed in the main aorta artery, help heart valves to close.

His work might influence William Harvey to perform an investigation in order to discover the chambers of the heart.

Thus, the correct answer is - False.

How would you justify Ivan Pavlov use of animals instead of human beings? Give 4 justification

Answers

Because animals are simple models, and humans are more complex. Also, in the 1800’s it was generally accepted that putting a human in a cage like a dog, in order to study how they react to a single stimulus would have been unethical at least, and likely torture. To make sure his test subjects weren’t reacting to previously learned stimulus, he needed animals who didn’t have much history. Young dogs, in pavlov’s case. Using young dogs is relatively easy, but using young human children has many more ethical issues. During his research on the physiology of digestion in dogs, Pavlov developed a procedure that enabled him to study the digestive processes of animals over long periods of time. He redirected the animals digestive fluids outside the body where they could be measured. Does that sound like something you and your family would like to sign up for? Being in a lab for months and surgeries to have your stomach fluids and saliva go through tubes, but consider that he would have had to use children. Would you rather your own child or a random dog?
