The primary function of the chloroplasts in a plant is to convert light
from the sun into glucose and energy in a process that is known as
photosynthesis. This energy is then used by the plant cells for
incredibly important functions such as growth and repair, so the chloroplasts are amongst the most necessary parts of any plant.
Toward the end of depolarization, voltage-regulated <u>slow calcium</u> channels would open while the sodium channels close.
<h3>What is cardiac cycle?</h3>
Cardiac cycle can be defined as a complete heartbeat of the mammalian heart and it comprises sequential-alternating contraction and relaxation of the atria and ventricles, in order to allow blood flow unidirectionally (one direction) throughout the body.
<h3>The stages of cardiac cycle.</h3>
Based on scientific evidence, the cardiac cycle in living organisms happens in two (2) stages;
<h3>What is depolarization?</h3>
Depolarization of the mammalian heart is a process which involves an orderly passage of electrical current sequentially through the heart muscle within the four chambers (4) of the heart such as atria and ventricles.
Toward the end of depolarization of the mammalian heart, voltage-regulated <u>slow calcium</u> channels would open while the sodium channels close.

The correct answer is C - carbon dioxide.
The distribution of gases in the earth's atmosphere is as follows:
1. Nitrogen - 78 %
2. Oxygen - 21 %
3. Argon - 0.93 %
4. Carbon dioxide - 0.038%
Nitrogen, oxygen and argon are permanent gases whose percentage in the atmosphere does not change from day to day.
Gases such as carbon dioxide, nitrous oxides, methane, and ozone are known as trace gases which make up 0.1% of the atmosphere.
I think you meant element?
Then it is Krypton because it is in period 4 in group 18, the noble gases.
