Answer: 43.
Explanation:
Mass number is the sum of protons and neutrons of an atom.
The number of prortons is the atomic number, so you can write:
Mass number = atomic number + number of neutrons. From which you get;
number of neutrons = mass number - atomic number = 80 - 37 = 43
All the atoms of a given element have the same number of protons. That is why the number of protons idenfies the elements and is called atomic number.
The number of neutrons of a given element may be different for different atoms of the same element.
The atoms of an element that have different number of neutrons are called isotopes. So, different isotopes of the same element have same atomic number but different mass number.
Hyperventilation<span> will blow off carbon dioxide which reduces the alkaline component of the </span>blood<span>, resulting in acidosis and a lower </span>blood pH<span>. (See Andromeda Strain). This is why re-breathing into a bag to increase carbon dioxide in your </span>blood will make you feel less faint. Basically <span>It increases the pH ... you can look at CO2 as an acid ... and when reduced ... alkalinization of the pH occurs</span>
Across:
10. The circulatory system transfers nutrients, gases, liquids, and heat around the body.
11. The circulatory system transports heat, which helps regulate temperature.
13. The place where oxygen enters the blood and carbon dioxide leaves the blood. Lungs.
15. A gas that is transported in arteries from the lungs to the rest of the body via the heart. Oxygen.
Down:
2. The heart, blood, and vessels. Circulatory System.
4. Blood in arteries is bright red because it is rich in oxygen.
6. A waste gas that is transported in veins from the body to the lungs via the heart. Carbon di Oxide.
<u>Explanation:</u>
The circulatory system includes blood vessels, blood, and heart. This system provides the body tissues with oxygen and some nutrients. It also carries hormones and eliminates needless waste products.
This transportation takes place between the cells via blood throughout the body. The channel that blood passes through is a blood vessel that is pumped by an organ called heart. The heart directs the blood passing all over the body.
The lungs are a duo of air-filled, spongy organs positioned on both sides of a human's chest. Its main function is to take in air present in the atmosphere and transfer oxygen to the bloodstream. From where it gets circulated throughout the body.
