Answer: Insulin Growth factor 1 (IGF-1)or Somatomedin C.
This is a <u>peptide hormone produced in the liver with a profound effects on growth at childhood stage. </u> Its secretion begins <u>slowly at infancy</u>, reaches<u> peak at puberty,</u> where it <u>influences growth sprout and remains at the plateau at old old age</u>. This secretion is stimulated by the <u>Growth hormone</u>.GH
However, its secretion is inhibited, by malnutrition, absence of Growth hormones receptors, non-response to Growth hormones stimulation; and blood concentration levels varies with insulin levels, types of nutrition, exercise and age.
Elevated Levels
Growth hormones is release into the blood stream from the pituitary gland.This is followed by its stimulation of synthesis of IGF-1 by the liver. <u>This hormone in-turn promotes the growth of the body systems which occurred by promoting the growth of cells of the body of certain organs especially; of the skeletal muscles, bones kidney, liver etc. </u>
The elevation of blood levels of GH, leads to corresponding over-stimulation of the liver to produce IGF-1. This leads to increase in system growth of body cells through rapid growth of general body cells.and thereforeT growth sprout.
Metalloid, it includes: boron, silicon, germanium, arsenic, antimony, tellurium and polonium
It is not C because animals use cellular respiration to transfer CO2 into Oxygen in the mitochondria.
It could be considered A because in food chains, plants are the primary producers of food chains. These primary food chains go through photosynthesis in order to "breathe" and make food. So the best answer to me is A.
*Though, if you dig deeper, the process that occurs in most ecosystems could be the answer because most ecosystems have plants because plants are the bottom of the food chain, without plants, there is no oxygen for the mammals to breathe. **** Ask your teacher/professor upon this question and be sure to include the main points in my conclusion.
This climate is warm.
The animals in the tundra are strong to live in such an environment.
I don't know what the rest of that stuff is sorry.
