Answer:
Oxygen or Minerals or Sugars (Oxygen is the most relevant one)
Explanation:
To survive, every cell must have a constant supply of vital substances such as sugar, minerals, and oxygen, and dispose of waste products, all carried back and forth by the blood cells. Without these substances, cells would die in a very short period of time.
Given what we know, we should observe the objects falling at the same speed in both the tower and vacuum scenarios, but not in the water.
<h3>What affects the speeds at which these objects fall?</h3>
- The falling speeds in both air and a vacuum will be the same for both objects.
- This is because falling speed is determined by gravity and is independent of the mass of the objects falling.
- The same will occur in water if and only if the densities of the two objects are equal.
Therefore, given that we can safely assume that the densities of the two objects are different from one another, we can confirm that while the objects will fall at the same speed in air and in a vacuum, this will not be the case in the deep pool.

Answer:
The best way to determine if these populations form part of the same species is to study the existence of reproductive isolation between populations. Moreover, the result of an experiment based on the study of reproductive barriers may be complemented with molecular biology approaches that determine the level of sequence homology between populations
B is not part of the cell theory; there are many types of cells that do not have cell walls, so the statement cannot even be generally true.
