Answer: The correct answer for the blank is-
Energy is released from ATP ( adenosine triphosphate) when high energy phosphoanhydride bond ( present between two phosphate) is broken down or hydrolyzed.
This results in the formation of ADP ( adenosine diphosphate) and Pi ( inorganic phosphate).
Therefore, hydrolysis of ATP releases energy.
Every time you eat a cookie or candy bar, your blood sugar increases. This triggers an increase in the hormone insulin. Insulin<span> is a hormone made by the pancreas which allows your body to use sugar (glucose) from carbohydrates in the food that you eat, or to store glucose for future use. </span>Insulin<span> helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia).</span>
Answer:
Primary succession is one type of the ecological succession which takes place on the land devoid of vegetation or barren land.
The species which first flourishes on this barren land are known as pioneer species which includes the species of bryophytes and pteridophytes like lichens and mosses.
These lichens and mosses help breakdown the barren rocks through chemical leaching and help increase the nutrient content. This allows the ferns and small pteridophytes to grow.
Then the area is colonized by the intermediate species which includes herbs, shrubs later trees. These intermediate species help attract the animals and thus help establish the biological community.
Thus, Lichens mosses → herbs→ shrubs →trees.
<em>zygote</em> is the diploid cell that results from the fertilization between an egg and sperm
<em>sperm</em> is the male reproductive cell that is responsible for a baby to born
