Answer:

Option A , 10 %

Explanation:

Only 10% of the energy is passed on to each trophic level of an energy pyramid. This is because most of the energy available at any trophic level is used by an organism in internal bodily activities like cell respiration, ATP production, several life processes, metabolism etc. Thus, even though a large amount of energy is taken at a trophic level, nearly 90% of it is used by the organism itself and thus only 10% of the total energy is available for passing onto the next level. This is the reason why organism at the apex of an energy pyramid receives the least energy.

A(n) <u>anticondon </u>is a group of three bases on trna that is complementary to a specific mrna codon. poly-a tail cap codon anticodon

The main function of an anticondon is to form a pair with the condom by mating in order to form an RNA chain, this chain is a sequence of three nucleotides that form a unit of genetic code in a transfer RNA molecule.

How are homeostasis and cellular respiration mutually dependent on one another?

Arturiano [62]

Cellular respiration describes the process of oxygen and glucose and converting into water and carbon dioxide. Homeostasis is a term which refers to biological processes in which living things must maintain stable and equal conditions for survival. Cellular respiration which uses oxygen and glucose must be able to sustain life by releasing energy which is called ATP, the ATP which is produced enables many biological processes that keeps organisms alive. Cells need energy to grow, move, and function. The process of homeostasis enables cellular respiration to produce enough molecules which can sustain the development of the cell. Without homeostasis cellular respiration would cease to function and without cellular respiration the process of homeostasis would not occur. Homeostasis regulates how much molecules have to be expended in order to produce energy for the process of cellular respiration.

When platelets attach to collagen threads in an injured vessel the platelets swell, form extensions and then stick together. as

Brrunno [24]

Answer is: platelet plug

When platelets stick to each other and to the blood vessel they form a plug in the hole of the vessel. This process is called platelet aggregation.

Before the plug forms, a platelet will stick to the blood vessel (adhesion), change its shape and signal other platelets to come help (activation and secretion). Then they stick to each other (aggregation).

A zygote (i.e., a fertilized egg) undergoes development to grow. What mechanism is used to generate more cells?

pentagon [3]

Answer: Mitosis

Explanation:

Since meiosis helps only in the production of gametes, mitosis helps the somatic cells in the already fertilized egg (zygote) to do the following:

- multiply their number, thus aiding growth

- form new cells like red blood cells to transport oxygen, white blood cells to fight infection, liver cells etc

Thus, for growth mitosis is the mechanism used to generate more cells
