Inhalation and exhalation move air into and out of the lungs. what happens when you inhale and exhale? drag the labels to the co
Arada [10]

When you inhale or breathe in air, your diaphragm will contract or tighten and it will move downward. This will result to an increase in space in your chest cavity where your lungs will expand. The intercostal muscles located between your ribs will also help in the enlargement of the chest cavity. When your lungs expand, air will flow through your nose or mouth. The air will travel through your wind pipe and into your lungs. It will pass through your bronchial tubes and it will eventually reach and enters the<span> alveoli or the air sacs.</span> 

W<span>hen you exhale or breathe out on the other hand, your diaphragm will relax and it will move upward into your chest cavity. The intercostal muscles will likewise relax resulting to the reduction of space in the chest cavity. When the space </span><span>in the chest cavity gets smaller, air that is carrying carbon dioxide will be forced out of your lungs and windpipe and it will eventually go out of your nose or mouth.</span>

Sodium (Na) ____<br> atomic # 11<br> atomic mass: 23
SVETLANKA909090 [29]

Find # of electrons and draw them onto the Bohr model.

Assuming the atom has a neutral charge, the number of electrons equals the number of protons.  The number of protons is given by the atomic number, 11, so there are eleven electrons.

From the inner "ring" to the outer "ring":

1.  The first "ring", closest to the center of the atom, can take two electrons.

2.  The second "ring", level 2, can take the next six electrons.

3.  The rest of the electrons (three) can fit on the outermost ring.

Which of the following describes the role of cyclic amp (cAMP) <br><br> in hormone responses
Anon25 [30]

Hello. You forgot to enter the answer options. The options are:

"A. cAMP opens a pore for steroid hormones to enter the nucleus. B. cAMP receives a message from a nonsteroid hormone and carries the message into the cell. C. cAMP receives messages from mRNA to begin protein synthesis. D. cAMP are molecules that bind and captures the nonsteroid hormone"

Answer:

cAMP receives a message from a nonsteroid hormone and carries the message into the cell.

Explanation:

cAMP is a very important molecule for the functioning of our organism. That's because cAMP is a cellular messenger responsible for receiving a message from a non-steroid hormone and carrying it to the cell.

The cAMP is formed by the enzyme adenylyl cyclase, which is present on the inner side of the membranes. This enzyme catalyzes a reaction with the ATP molecule, giving rise to cAMP.
