<h3><u>Answer;</u></h3>

D) A sky diver reaches terminal velocity when he stops accelerating.

<h3><u>Explanation;</u></h3>
  • <em><u>Balanced forces are forces that act in opposite directions and are equal in size. </u></em>When an object is acted upon by unbalanced forces then the object stays still or at rest or continues moving at a constant velocity in the same direction.
  • Unbalanced forces cause an object or a body to change its motion or velocity and direction.
  • <u><em>A sky diver who reaches terminal velocity when he stops accelerating, experiences balanced forces. Terminal velocity being a point at which the drag force is equal to the force of gravity.</em></u>

D) A sky diver reaches terminal velocity when he stops accelerating.
F = mass*gravity = Force of air resistance pushing up on the person
<span>Reached terminal velocity = acceleration = zero </span>

What happens during the light reaction of photosynthesis?.
Genrish500 [490]

Answer:

Chlorophyll absorbs the red and blue segment of the white light and photosynthesis occurs most efficiently at these wavelengths.

When the light falls on the plant, the chlorophyll pigment absorbs this light and electrons in it gets excited.

This process occurs in a complex protein system which is collectively called as a photosystem.

Sodium and potassium ions move in and out of the axon when the membrane is ______
Ostrovityanka [42]

Answer:

Answer : Depolarized

Explanation:

Sodium and Potassium ions tend to move inside of the axin when the membrane is depolarized.

A change in polarity occurs in the axon membrane when a nerve impulse travels across it.  At the beginning of an action potential or nerve impulse , the ions of sodium tend to move inside of axon causing depolarization. As a result potassium ions tend to move outside of the axon causing re polarization. Hence, this effect causes the nerve impulse to travel in one direction only inside the axon.

Why is it thought that the majority of natural selection is stabilizing selection?.
Advocard [28]

Answer:

Why is it thought that the majority of natural selection is stabilizing selection? Mutations produce extreme phenotypes, which are selected for. Artificial selection is the most common, which is a type of stabilizing selection. Most mutations are beneficial and produce intermediate phenotypes.
