The process, which contribute to the pattern of animal diversity observed is EXTINCTION EFFECTS BOTH LOCALLY AND GLOBALLY.
Biodiversity refers to the varieties of plants and animals, which are obtainable in a particular ecosystem. A high level of biodiversity is always consider to be very important for any ecosystem. The reduction in diversity that was observed was due to mass extinction of some plants and animals. <span />
Answer:
<em>Nutrition and Growth.</em>
Explanation:
Nutrition: Nutrition is defined as the ability of living organisms to feed. The reason for feeding is to enable living things live and carry out life processes like growth, respiration and reproduction. While all green plants can manufacture their own food through a process called autotrophic or holophytic nutrition. all mamma can not manufacture their own food but depend on plant directly or indirectly for their food, hence this type of nutrition is called heterotrophic nutrition.
<em>Growth: </em>Growth is defined as an irreversible or permanent increase in size, dry mass or weight of an organism due to addition of living proton plasmic materials. The purpose of growth is to enable organisms to repair or replace damaged or old tissue in the body. The food eaten provides the basis for growth of organisms.

Thr answer is c sorry if am wrong
The correct answer is option A. They either match up with a receptor molecule on the surface of the cell or enter the cell through the membrane.
The intercellular signals are the signals, which transfer the signals from one cell to the another and the intracellular signals are those signals, which carries message within the cell.
The intercellular signals may or may not be transferred through the gap junctions. The chemical signals are one of the type of the cell signals. The chemical signalling molecules generally have a receptor on the cells, where these molecules can bind and can be cause the activation of the cell. The chemical signals can also enter into the cells through active transport and facilitated diffusion. So, these type of transports does not go through the Gap junction.
