Reaches the adult stage is the correct answer. When an intervebrate reaches the adult stage it has most likely stopped growing and can finally begin reproduction, passing further down the line his genes and the genes of his ancestors.

Answer: adult

Invertebrates are the animals that do not possess a vertebral column. The examples of invertebrates includes arthropods, annelids, cnidarians and mollusks. Invertebrates are the largest class of organisms. They consists of three common parts called as head, thorax and abdomen. The structure restricts any change in the size or length after reaching the adult stage.

Briefly outline the steps involved in glycogen synthesis and breakdown and explain the regulatory mechanism involved in glycogen
Elenna [48]

Answer:

Glycogen is synthesized and degraded by different pathways, which provide greater flexibility for energy production through its degradation or for storage in its synthesis and thus maintain control of both metabolic pathways.

Explanation:

Synthesis and degradation pathways:

1º.- activation of glucose units at UDP-glucose.

UDP-glucose is an activated form of glucose, which is formed in a reaction catalyzed by UDP-glucose, which is formed in a reaction catalyzed by UDP-glucose pyrophosphorylase. This reaction is an example of biosynthetic reactions that are directed by the hydrolysis of pyrophosphate (PPi-2Pi).

Many biosynthetic reactions are directed by the hydrolysis of pyrophosphate, which catalyzes pyrophosphate hydrolase or pyrophosphatase, and is very favorable thermodynamically.

2nd.- polymerization or addition of glucose units to glycogen. Two steps: addition and branching.

 UDP-glucose acts as the giver of glucose units for glycogen synthesis. Glucose transfer

from the UDP-glucose to a growing glycogen chain is catalyzed by glycogen synthase.

A branching enzyme [amyl (1,4 -> 1,6) -transglucosidase], moves a chain of about seven glucose residues, to form

bonds (α1-> 6) at the branching points.

To start glycogen synthesis, glycogen synthase is only effective when it is linked to glycogenin. Glycogenin is

an oligosaccharide carrier protein formed by glucose units with linkages (α1-> 4).

Selection that acts, over evolutionary time, to enhance traits that increase an individual's ability to mate frequently or with
blagie [28]

Answer:

Selection that acts, over evolutionary time, to enhance traits that increase an individual's ability to mate frequently or with quality partners is known as <u>sexual selection.</u>

Explanation:

Sexual selection : The process through which males and females attempt to maximise their chances of reproductive success is called sexual selection. It is a form of natural selection. Charles Darwin suggested sexual selection. Animals compete with others of the same species for the chance to mate.

<u>For example:</u> Male widow-bird grows exceptional long tail feathers, females lack tail feathers.
