Answer:
(a) Allen's rule
Explanation:
It is a heat-conservation mechanism that prevents heat loss from the body. Heat gain and heat loss can be maximised and minimised by lowering the surface area to volume ratio of the body. Small animals are uncommon in the polar regions due to their larger surface area and lower volume.

A chemical change occurs when both the physical properties of a substance and its identity change. The correct option is C.
What are chemical changes?A chemical change is a change when the identity of a substance changes, and it converts into a new substance with new characteristics and a new identity.
When iron comes in contact with oxygen, it changes into rust, and it is a chemical change. A chemical change is a transformation in which the substance's chemical composition is altered through atom rearrangement. Atomic alterations cause changes in the molecular structure.
Chemical properties are those property properties of a substance that does not depend on the quantity of that substance.
Therefore, the correct option is C. both the physical properties of a substance and its identity change.

Why is it difficult to male level 4 organs in a lab?
Answer:
By providing an example using one organ for each of the four levels of complexity, we have the following:First level organ: Skin; this is because it takes up a few cells. Second level organ: Windpipes; this is because they have more complex shapes with multiple cells. Third level organ: Stomach; this is because the stomach has to act on demand instead of a flow. Fourth level organ; Heart. The reason it is difficult to make level four organs in a lab is that it has a complicated architecture with several cells, blood vessels and tiny capillaries included. So far, scientists are yet to fully develop solutions for the level four organs and hence, difficult to create in a lab.

In scenarios 2 and 3, the simulation settings are such that it takes 30 days to run the vaccination campaign and 14 days to develop immunity. Explain the logic behind these setting choices. Hint: there are two reasons, one is biological and one is logistical.
The two possible reasons for these setting choices are that it takes to the body around 14 days to develop immunity and that vaccinating a lot of people is logistically demanding.
What are vaccines?Vaccines are biological substances that help the body develop immunity against a virus, bacteria, etc. This is possible because vaccines contained a weakened or modified version of the pathogen that would help the body secrete specific antibodies for the real pathogen.
What is the possible reason for the 14-day setting?Immunity does not occur immediately, indeed, it takes the body up to 14 days to build up immunity. This includes the modern vaccines.
What is the possible reason for the 30-day setting?On the other hand, giving vaccines to large populations is quite demanding and challenging. Due to this programs with multiple weeks including four-week programs are ideal.
