Answer:

The correct answer is A. pollen.

Explanation:

Pollen is a very efficient way to colonize and reach further. It's believed that this adaptation is the main reason why land plants could colonize so many environments. The fact that pollen is little and easily transported also was very important.

During the absorptive state, metabolism adjusts to either provide energy for immediate use or store excess energy to be used lat
Effectus [21]

Answer:

A. Catabolic

B.Anabolic.

C. Anabolic

D. Catabolic.

E.Anabolic

F. Catabolic

G. Anabolic

H. Catabolic

Explanation:

Catabolic process is a metabolic processes that breakdown complex or larger molecules into smaller sizes by releasing energy.

The examples of such metabolic processes are;

Glucose is used as the primary fuel for energy

Dietary carbohydrate from a meal is digested and absorbed as monosaccharides, mainly glucose

Dietary protein from a meal is digested and absorbed as single amino acids.

Fatty acids are used as fuel sources for some tissues.

All this processes are catabolic processes because large molecules are broken to smaller ones and all this processes release energy.

Anabolic process is a metabolic process where smaller molecular are build up to form larger molecules and this requires the input of energy.

Examples are;

Glucose is used as the primary fuel for energy

Excess glucose is stored as glycogen in the liver and muscle.

Excess glucose is converted to fatty acids and stored as part of the triglyceride molecule in adipose tissue

Excess tatty acids combine with glycerol to form which are stored in adipose tissues.

All these processes requires the build up of smaller molecules to larger molecules and requires input of energy.
