which hormone signals the breakdown of glycogen in the liver increasing glucose in the blood?

Answers

Answer:

The answer is glucagon

Explanation:

When the blood sugar level drops down, the glucagon hormone converts the glycogen into glucose and raises its level in the bloodstream.

Glycogen is a main source of energy for the body. Glycogen is stored in the liver. When the body needs more energy, certain proteins called enzymes break down glycogen into glucose. They send the glucose out into the body.

Which hormone stimulates the breakdown of glycogen in the liver into glucose?

Glucagon's role in the body is to prevent blood glucose levels from dropping too low. To do this, it acts on the liver in several ways: It stimulates the conversion of stored glycogen (stored in the liver) to glucose, which can be released into the bloodstream.

How does glucagon increase blood glucose?

When your blood glucose levels trend lower or fall too low (hypoglycemia), your pancreas releases more glucagon. Glucagon helps blood glucose levels rise back up in multiple ways, including Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream.

dna is synthesized through a process known as _____.

Answers

Dna is synthesized through a process known as DNA Replication.

DNA is synthesized through a process known as - DNA replication or semiconservative replication.

DNA replicationsynthesis of new DNA. a double-stranded DNA molecule is copied to produce two identical DNA molecules.is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information or DNA.the replication takes place in the following steps:step 1

in the nucleus of the cell the DNA double helix separates after that an enzyme named DNA helicase attaches to the DNA molecule and moves along the molecule and 'unzips' the two strands of DNA

Step 2

since nucleotides are floating in the nucleus that means there are A, G, T and C's floating around also. these are bases that form hydrogen bonds with the bases of DNA strands.

Step 3

the enzyme they call DNA polymerase catalyzes the formation of the sugar-phosphate units at the sides of the helix and connects one base pair to the next one

Thus, DNA is synthesized through a process known as - DNA replication or semiconservative replication.

Which of these choices is a benefit of the Endangered Species Act?

A. Can prohibit removal of dangerous animals
B. Can interfere with economic progress
C. Can cost a lot of money to enforce
O D. Can save species from extinction

Answers

Answer:

D. Can save species from extinction

Explanation:

As saving species from extinction is what Endangered Species Act would want as endangered means that the animal is close to dying and is in danger of being there no longer

Benefits of the Endangered Species Act can prevent the extinction of certain species. So, the correct option is D.

What is Endangered species Act?

One of America's most important and effective environmental legislation is the Endangered Species Act. It shows that Americans are willing to cooperate in order to preserve and safeguard the species that are most in danger of going extinct for good.

For landowners, government organisations, and concerned citizens, the legislation offers reasonable, well-balanced options for preserving endangered wildlife and its ecosystems. There are three crucial components in it:

1. Preventing harm or extinction of the listed species

2. Creating strategies to reestablish healthy populations

3. Protecting habitat, which is crucial to the survival of these species.

Therefore,  the correct option is D.

Making changes to the secondary structure of hair has a different outcome than making changes to its tertiary or quaternary structure. How does this outcome differ

Answers

The outcome differs in the way that the protein folds itself at each level. The changes in the way that it folds lead to:

modifications in the function, shape or in the combination with other proteins.

Protein has different levels of structure. Each of them is related to how the amino acids and other molecules interact with each other. Hair is made of proteins, so if one of the structures is affected, the hair is too.

Let's analyse what happens in each level of structure:

In the case of the primary structure, which is the sequence of amino acids, the modification will give a non-functional protein that will not fold into the following structural level. So, there won't be new hair.For the secondary structure, a modification here can lead to a different folding. In other words, it can change from an α helix to a β pleated sheet or the other way round. This will give a different shape to the hair, like curly or straight.A modification in the tertiary structure modifies the interaction of the R groups in the protein, so the three-dimensional structure that this interaction gives will change, giving a different type of hair.Lastly, if we modify the quaternary structure, the protein won't interact with some proteins, but it may interact with others.

In conclusion, the modification of the secondary structure changes the interaction between the elements of the protein giving hair with different shapes.
