what type of ions carry the impulse across the synapse from one neuron to the next ?

Answers

Answer 1

It's the sodium ion.

When a neural impulse is fired in both neurons, it is always cause by an excited electron in one neuron moving to the other neuron to destabilize the balance of ions trying to keep them at equilibrium. This action either depolarizes or hyper-polarizes the membrane. If it does, then sodium ions--the key deficient ones--can flow into that region of low charge and maintain that state of low charge, keeping the cell membrane stable.

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.

Based on information from the cladogram and the data table shown below, which of the following best describes the evolutionary history of rabbits?


Claws/Nails Feathers Jaws Lungs Mammary glands
Bird X X X X
Hagfish
Lizard X X X
Rabbit X X X X
Salamander X X
Tiger X X X X
Trout X


Image depicts a cladogram with hagfish, trout, salamander, lizard, bird, rabbit, and tiger represented. Trout diverge from hagfish with the introduction of jaws. Salamander diverges from trout with the introduction of lungs. Lizard diverges from salamander with the introduction of claws and nails. Bird diverges from lizard with the introduction of feathers. Rabbit and tiger diverge from lizard with the introduction of mammary glands.
They are more closely related to tigers than they are to birds.
They became able to produce mammary glands as a result of lacking feathers.
They evolved into a separate species due to the presence of mammary glands.
They share a more recent common evolutionary ancestor with salamanders than they do with lizards.

Answers

Answer:

A. They are more closely related to tigers than they are to birds.

Explanation:

Short answer: I took the test

Actual explanation:

-If you look at the first graphic that you have, you will notice that rabbits and tigers have all the same boxes checked off. AND birds and rabbits only have 3 checked off.

-salamanders actually have less in common with rabbits than they do with lizards, salamanders have 3 things in common, and lizards only have 2, proving option D. wrong. (if you are wondering where I got that evidence, look at the chart) AND if you look at the cladogram, lizards are closer to the rabbits than salamanders meaning that lizards have a more common ancestor (I think?) But nevertheless, it it still wrong, because of the above evidence.

- The options with mammary glands are also incorrect for these reasons, B. makes no sense, literally no sense, why would not be able to produce mammary glands with feathers, so B, is automatically out. With option C, rabbits did not evolve into a whole new species, it is the clade showing that tigers and rabbits both have mammary glands. There is no showing of a new species on the cladogram, and I don't think that it makes sense to evolve into a whole species just because of mammary glands.

- Now, if you look at the cladogram again, you wills see that tigers and rabbits are closest together, meaning that they are closely related. BUT, birds and rabbits are also the closet together, so, refer back to point a, that the chart shows that birds only share 3 out of the 4 that rabbits and tigers share. so that's that.

So after doing the work, option A. Rabbits are more closely related to tigers than they are birds. (and If you read my long explanation THANK YOU I put time and effort into it to make it accurate :))

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.
