They are ineffective against viral infections because viruses can not be treated with antibiotics.
The answer is d. dormancy.
Dormancy is physiological condition during which growth and development are temporarily stopped. The aim of this condition is to preserve energy by minimizing metabolic activity, usually because of inadequate environmental conditions.
Dispersal refers to movement of individuals from one site to another. Fertilization means a fusion of gametes to develop a new organism.
Germination is a process of growing plant from a seed.
<u>Answer:</u>
<em>If no other changes occurred emigration would have a negative impact on the population density of a group of organisms.
</em>
<u>Explanation:</u>
<em>Emigration is the movement of a part of population out of an area into a new area. </em>It has a negative impact on the population of the old area and positive impact on the population of the new area.
Population density is the population per unit area that is population per square kilometer.
Thus population density will also be negatively affected by emigration. <em>Hence an area that previously was densely populated might become a sparsely populated area due to emigration. </em>
Normal development in tests requires a temperature. cremaster muscle contract or relax to move testes toward or away from the body or to maintain the acceptable temperature for testicular.
The body temperature regulation is controlled by the autonomic nervous system under the guidance of medulla oblongata which is in the brain system.
