What are the factors that affect the force of gravity between two objects?
Alecsey [184]

Answer:

Explanation:

Interesting question. Consider the formula that governs the gravitational formula

F = G * m1 * m2 / r^2

G is the gravitational constant. It does not change no matter where you are in the inverse, nor is it found to be different under normal circumstances. Since you have asked this in biology, you can assume that the circumstances are always normal./

m1 and m2 are masses in kg. The mass is invariant as well anywhere in the universe, except perhaps near or in a black hole.

r^2 is a distance in meters.

So the Force of gravity (in Newtons) varies directly as the masses involved and inversely as the distance squared.

The heart in fish only has two chambers, but oxygenated and deoxygenated blood never mix. Why is the 3-chamber heart of amphibia
loris [4]

Answer:

The correct answer is option d.

Explanation:

In a fish, the heart comprises two chambers, a ventricle, and an atrium. The deoxygenated blood comes through the body, moves into the atrium and then into the ventricle, from where it is pushed towards the body through the gills.  

The pumping of the blood via the heart takes place via the capillary beds of the gills and via the tissues’ capillary beds. When the blood come in the capillary beds of the gills it gets slow down. It moves gradually via its path to the tissues and requires skeletal muscular activity to help the blood to mediate towards the heart again. Thus, a fish is dependent upon the physical effort for blood to get circulated again to the heart.  

The heart of an amphibian-like the frog exhibits three chambers, two atria and one ventricle. In the process of circulation, that is, in the ventricle, the oxygenated and the deoxygenated blood gets mixed prior to being impelled out of the heart. However, amphibians possess lower metabolisms and thus, they need less oxygen. The requirement of a lesser amount of oxygen puts less pressure on the heart to provide blood with high oxygen. Thus, a heart comprising three chambers is suitable for the requirements of amphibians who could absorb oxygen via their moist skin.
