Answer:
a. Calcium is an electrolyte that assists in the transmission of nerve impulses.
Explanation:
In the process of muscle contraction, the action potential (electrical impulse) releases the calcium stored in the sarcoplasmic reticulum located in the muscle.
Calcium then flows into the cytoplasm, where the actin and myosin filaments are located, which will interact with each other to promote muscle contraction.
Thus, it can be concluded that calcium does play an important role in nerve impulse transmission.
Given the above statements, it is concluded that the correct alternative is "A"
.
As for the other statements: Calcium, as described above, also participates in the process of muscle contraction, however it is the muscle cells that contract, not the nerve cells (Statement B).
In addition, calcium does not participate in the formation of muscle cells (Statement C), nor can it make the blood slightly acidic (Statement D) because it has alkaline (basic) character.
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.
Answer:the arrival of the ribosome to a stop condon, such as uga
Explanation:I’m taking the test right now
At least two body systems are needed to perform the function of breathing because to ensure breathing, the body performs two respiratory movements: inspiration, which is the entry of air into the lungs, and expiration, which is the elimination of carbon dioxide. Pulmonary breathing is a process in which air enters our lungs and is subsequently eliminated. involving muscles and gaseous reactions.
<h3>What is the path of air inside the human body?</h3>
The air penetrates through the nasal passages, passes through the pharynx, larynx and trachea, bronchi, reaching the lungs where it travels through the bronchioles until reaching the alveoli, where gas exchange takes place. The difference between inspired and expired air is in the concentration of oxygen and carbon dioxide.
With this information, we can conclude that The entire process of gas exchange in the body, which is called breathing, takes place in three basic steps, which are pulmonary ventilation, which corresponds to the flow of air in and out of the lungs.
