1.  Respiratory brings oxygen and nutrients to the cells, while the circulatory

moves gases in and out of the blood. These work together because they have to exchange carbon dioxide and oxygen with each other.

2.   The main parts and functions of the respiratory system are, the nose, pharynx, larynx, trachea, bronchi, and the lungs. As I said in the first answer, The respiratory brings oxygen and nutrients to the cells.

3. The main parts and functions of the circulatory system is the heart, lungs, arteries, veins, coronary, and portal vessels. The circulatory system moves gases in and out of the blood.

4.  There are two main parts in your lungs, the pharynx, and the larynx. So, when you swallow food, the epiglottes blocks the entrance to these two main parts. Simply..if you could breath while doing this..I think you could die.

5. They are connected to capillaries that distribute blood to and from all the cells.

Place the steps for the formation of the enzyme pepsinogen in the correct order.
Volgvan

The steps for the formation of the enzyme pepsinogen in the correct order is as 1, 4, 2, 3.

Pepsinogen is a chemical that is created by the cells that exist in the stomach. During digestion, pepsinogen is converted into pepsin by the acid in the stomach, and pepsin is responsible for breaking down the proteins in food. The formation steps are as;

Step 1: The DNA strands unwind, and  RNA polymerase binds to the template strand.

Step 2: The synthesis of mRNA begins. The amino acids assemble to form peptide.

Step 3: The mRNA undergoes intron splicing and exits the nucleus.

Step 4: The tRNA moves through mRNA with the activated amino acids attached to it.

The complete question is attached.

You can also learn about Pepsinogen from the following question:

During sensation and perception, sensory receptors on the skin transduce information and then send this information to
rewona [7]

The area of the brain located in the parietal lobe, responsible for processing information from sensory receptors on the skin is the <u>somatosensory cortex</u>.

<h3>What is somatosensory cortex?</h3>

It is that brain area responsible for processing and treating information of a sensory nature that comes from the skin, muscles and joints.

<h3>Characteristics of somatosensory cortex</h3>

  • It receives and interprets all the information that comes from the tactile system.

  • Sensations of pain, temperature, pressure, as well as the ability to perceive the size, texture, and shape of objects are perceived by this section of the cerebral cortex.

Therefore, we can conclude that the sensory receptors receive information from the outside regarding touch, pain and temperature and transmit it to the somatosensory cortex.
