Question

With ______ bias, even though there are many possible directions of movement, actual flows are restricted to only one or a few.

A) Directional
B) Flow
C) Limited
D) Restricted

Answer 1

The answer to the question is A) Directional bias, which describes a situation where movement, such as blood flow, is restricted to a single direction.

Step-by-step explanation:

The correct answer is A) Directional bias. In the context of biological systems, such as blood circulation, directional flow refers to the movement that is restricted to one or precisely defined pathways. For instance, blood flow through the lungs and back to the heart is referred to as pulmonary circulation, exemplifying a type of unidirectional circulation because the blood moves in a single direction from the body, through the lungs for oxygenation, and back to the heart.
