Answer:
Infectious diseases are diseases caused by living organisms like viruses and bacteria. They can be passed from person to person through body secretions, insects or other means. Examples are SARS, influenza, the common cold, tuberculosis (TB), Hepatitis A and B.
Answer:
The influenza virus has a negative sense RNA genome. In order to replicate, this means that the virus must first produce positive sense mRNA in order to produce necessary enzymes. Once the enzymes are translated, replication can take place. Positive sense cRNA is then made from the original negative sense RNA, using the enzymes. Negative sense RNA progeny are then made from the positive sense cRNA. The final viral progeny eventually bud from the host cell, ready to infect other cells.

Answer:
Cellular Differentiation
Explanation:
During the germinal period of prenatal development, some cells become part of the brain, some become part of the leg, some become part of the stomach, and so on. The term for this process is Cellular Differentiation
Answer:
a change in pH diminishes the effectiveness ò the enzyme
<u>Answer:</u>
It functions in a way similar to ATP as a rechargeable battery, because it can store energy and then release it.
<u>Explanation:</u>
- ATP (Adenosine triphosphate) is an energy component in the cell as it provides energy required for various purposes of activities in the cell hence it is termed as the “currency” for energy.
- ATP produces ADP that is converted into the energy for the flow of cellular activities and then ATPs can again be reused many times.
- As in batteries, ATP can also be recycled and recharged to get the required energy several times.
