For the environmental risk, it is much better to prevent pollution than to deal with it after it has already been made. When you deal with the pollution, it is hard to say that you can eliminate completely. So, prevention is the first strategy.
Answer:
A. Advantageous alleles do not arise on demand.
Explanation:
According to theory of evolution, heritable traits in organisms can change across the generations leading to their evolution. There are many evolutionary forces like natural selection, mutation, genetic drift etc. However, it is incorrect to assume that the advantageous alleles will always be selected in evolution. Accumulation of random mutations, genetic drift or bottle neck effect are independent of this factor. Also, organisms with different degree of beneficial traits can coexist in same time frame. Just because humans evolved in a particular direction does not mean that other organisms will also do so.
Cell specialization allows new cells to develop into a range of different tissues, all of which work together to make living organisms function as a whole. The process of cell specialization exactly how cells develop into their diverse forms is complex.
This is Adaptation !
An adaptation is when an animal adapts or evolves to it's environment.
^ There are more uses for the word Adaptation but in this example this is correct. Hope this helps !!!
The answer to this question is liver. The liver stores extra glucose and converts it into glycogen through glycogenesis. When the body's blood sugar drops, like when you don't eat for a long time and get hypoglycemia, the liver releases the glycogen into the bloodstream and restores the blood sugar level.
