The study of the relationship between structures and functions is at the very heart of biology. This relationship is expressed in living beings by the adaptation of the first to the second and poses a series of absolutely fundamental problems, such as the relationship between causality and finality, analogy and homology, structural improvement and evolutionary level, etc.
For example, the structure of the hand is related to its function, thanks to the fingers and the thumb it is easy to wear and store objects.
The zigzag structure of the intestine is related to its absorption function, as this makes it possible to increase the contact surface between the alimentary bolus and the intestinal wall, and thus to increase the absorption.
The answer is D.) the process where distribution of molecules is balanced out by their movement.

Answer:
HYPOTHESIS: IF the salinity of the solution decreases, THEN the vegetable mass increases.
Explanation:
Hypothesis, in an experiment, is a testable explanation or prediction made to solve an observed problem or answer a question. It shows how one variable called independent variable affects another variable called dependent variable. It is usually written in the "IF, THEN" format.
In this case, the question states that there is a relationship between vegetable mass and salinity of the solution. This means that the question has been asked that "Why is the vegetable's mass affected by salinity of a solution". Hence, a hypothesis can read:
IF the salinity of the solution decreases, THEN the vegetable mass increases.
