I also took this quiz and got this answer
Answer: Option C) They would not need to be transported through the body.
Explanation:
Red blood cells are a type of blood cell that have a biconcave disc shape and lack nucleus. They are transported around the body where they distribute oxygen.
Neurons, on the other hand, are a type of cell in the nervous system. They are of different types and are interconnected to one another such that they do not need to be transported at all while they transmit impulses around the body.
Thus, if red blood cells were shaped like the interconnected neurons, there would be no need for them to be transported through the body.
Answer:
Option (A).
Explanation:
Cell membrane or plasma membrane is made up of lipids and proteins with the small amount of carbohydrates are attached to it. This membrane maintains fluidity and separate cell's environment.
Small non polar and uncharged molecules can easily pass through the cell membrane by the process of diffusion. Carbon dioxide and water are small molecules that can easily pass through the membrane.
Thus, the correct answer is option (A).
Answer:
Theories may be revised over time as information is discovered or technology is developed.
Explanation:
A scientific theory is a term used when a statement tries to explain a natural phenomenon of nature based on scientific facts. In short, a theory is the representation of a set of hypotheses that was confirmed through an experiment and that tries to explain a phenomenon, but leaves room for revisions and updates to its explanation.
For this reason, we can say that theories are reformulated, revised and even discredited, when the advancement of scientific knowledge and technology allows the creation of new studies that show a different explanation and more consistent with reality.
