During one year a population of blue jays has zero population growth. which must be true about the blue jay population at the end of the year compared to the beginning of the year? it will have the same number of individuals in it. it will have the very same individuals in it. it will have become larger. it will have become smaller.

Option A, It will have the same number of individuals in it

Explanation:

When it is said that the population growth is zero, then it means that the number of people/individuals in a population remains same.

Or Population growth is zero when equal number of individual have died and taken birth at the same time.

For example -

Suppose the population of Blue jay a year ago was 1000, out of this 20 died after one month. In the remaining 11 months , 20 new individuals were born. Then, population growth of blue jay would be -

Hence, option A is corect

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
