Answer:
The correct answer will be option-E.
Explanation:
Chordae tendinae are the string-like structure in the heart which is composed of dense regular connective tissue called collagen and elastin proteins. They arise from the papillary muscles of the heart and branches out in the ventricle portion of the heart.
These play an important role in the closure of the AV valves to prevent the backward flow of the blood to the atria during ventricular contraction by holding cusps of the valve into the dome-shaped structure.
Thus, option-E is the correct answer.
Answer:
4
Explanation:
This is the answer because I have tested it and got it correct. As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria.
I'm not sure what you mean by "compartments", but the cardiovascular system consists of the heart, blood vessels, and approximately 5 liters of blood.
Answer:
Temperature and absolute brightness
Explanation:
The X-Axis of the diagram is heat, and it actually goes down in heat.
The Y-Axis is for brightness, and it works like a regular axis, meaning as it goes up, the number or unit of some sort, in this case luminosity, goes up.
