What does Darwin's theory of evolution suggest?

Which of the following is the correct rule of nucleic acids in the body?

Pepsi [2]

Answer: B. They contain genetic information

Explanation: The role of nucleic acids is to store the genetic information (DNA) and to decode that information into proteins (RNA). DNA is also the form in which genetic information is passed from one generation to the next.

Identify the true statements regarding liver glycogen phosphorylase a. Protein phosphatase 1 is abbreviated PP1. The binding of

katrin2010 [14]

Answer:

Liver phosphorylase a concentration decreases when glucose enters the blood.

The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form

As the concentration of phosphorylase a decreases, the activity of glycogen synthase increases. to the inactive form

Explanation:

Protein phosphatase 1 (PP1) is a phosphatase enzyme known to remove phosphate groups from serine/threonine amino acid residues. PP1 plays diverse biological roles including, among others, cell progression, control of glucose metabolism, muscle contraction, etc. In glucose metabolism, PP1 regulates diverse glycogen metabolizing enzymes (e.g., glycogen synthase, glycogen phosphorylase, etc). In the liver, glycogen phosphorylase catalyzes the rate-limiting step in glycogenolysis by releasing glucose-1-phosphate. Glycogen phosphorylase a is converted (and inactivated) into the b form by PP1, which catalyzes the hydrolysis of the phosphate bond between serine and the phosphoryl group. In the liver, glucose binds in order to inhibit glycogen phosphorylase a, thereby inducing the dissociation and activation of PP1 from glycogen phosphorylase a.

According to the cladogram below, which of the following organisms had a

Cladograms are graphic representations of the relationship between different taxa according to derivated characters. Option A is correct. Group D has a segmented body and jaws, but no limbs.

<h3>What is a cladogram?</h3>

A Cladogram is a graph drown as a tree, which is based on cladistic analysis. It represents the common ancestral relationships and the emergence of different characters among the involved groups.

The tree-type graph is a ramified diagram that represents the relationship between the involved taxa.

The cladistic analysis follows the maximum parsimony criterium. Explains the character state from the point of view of the fewest changes through history.

Explains evolution with the minimal amount of evolutive changes.

It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny.

The sequencing term refers to lists of groups according to their relation. One group is the brother-group of the following one.

So the cladogram represents the relationship between groups according to a derived character.

The derivated character is any trait that a group passes to its descendants.

Through evolution, the characters change, and new changes are added. When referring to a derivate character, we mean that all the subsequent species in the cladogram carry the trait.

In the provided cladogram, segmentes bodies, jaws, limbs and other traits are derivated characters.

Group D has a segmented body and jaws, but does not express limbs.

This last trait emerged later in history and is expressed by groups E, F and G.

Option A is correct. Group D.
