In this example of evolutionary development, we can see a selective advantage.
Developing of new characteristics, in this case, the spots on moth's wings is a part of the process of adaptation of organisms to their environment.
The new characteristics are acquired through mutations and natural selection filters the ones that are the most beneficial for the holder.
For example, a mutation which results in moths having shorter wings is disadvantageous, because it makes the individual who possesses it less likely to survive and reproduce.
On the other hand, developing of spots that resemble eyes can be advantageous, since it enables the holder of the trait to be more successful and more likely to leave offspring.

I believe you’re referring to the body’s fight or flight response.
Answer:
Immune
Explanation:
The immune system helps to protect our body from all sort of organisms ranging from invading toxins and micro-organisms which negatively affects an individual’s health and well being.
Stress has an adverse effect on the immune system such that it weakens and suppresses the functions of the required antibodies in the body system. This is the reason why many aged people fall sick because they have gone through more stress when compared to younger people.
Mitosis helps in the growth by means of hyperplasia. It also helps in reproduction in single celled organisms.
Neuron and Red Blood Cells doesn't undergo cell division once formed.
Osteoblasts help in forming new bones and joining old ones after there's a fracture in bone.
<h3><u>Explanation:</u></h3>
Mitosis is the process by which a cell divides into two daughter cells. It helps in growth of multicellular organisms as well as reproduction in single celled organisms.
The Red blood cells are formed from the bone marrow megakaryocytes and never undergo mitosis. Same are the neurons which are formed from stem cells and never undergo cell division.
The osteoblasts come into action as the bone breaks. They diposit new calcium compounds between the broken part of bones. This leads to irregular growth of bones between them which is then remoulded and brought back to shape by osteoclasts and osteocytes.
