C. The problem of endangered species
Cell has cell membrane<span> (also known as the </span>plasma membrane<span> or </span>cytoplasmic membrane<span>) it is a </span>biological membrane<span> that separates the </span>interior<span> of all </span>cells<span> from the </span>outside environment.<span> The cell membrane is </span>selectively permeable<span> to </span>ions<span> and </span>organic molecules<span>and </span>controls the movement of substances<span> in and out of cells.</span><span>The basic function of the cell membrane is to protect the cell from its surroundings.</span>
<span>An amphibian that lacks lungs and breathes entirely through its skin would have to be smaller than an amphibian with lungs so that the small oxygen intake correlates with
the small surface area of the amphibian. This would then allow it to breath efficiently.</span>
Answer:
3 meter / second square.
Explanation:
The acceleration is defined as change in velocity over a period of time interval. Mathematically it can be written as,
acceleration = change in velocity / time
acceleration = 16- 4 (meters/second) / 4 seconds
acceleration = 12 meters/second / 4 seconds
acceleration = 3 meter / second square.
So the answer shows that the car accelerates 3 meter / second square.
