What are the 3 principles of heredity that Gregor Mendel discovered?

1 answer:

7 0

Based on the information shared by the experiments of Gregor Mendel, the statement “traits are passed from parents to offspring independently of one another” is actually a theory and not a hypothesis or observation. It cannot be a hypothesis as it is already tested and proved. Hypothesis is something that has not been proved. An observation is something that has been observed, but never proved. Gregor Mendes proved this theory or hypothesis in the laboratory and so it is surely a theory.

c) Blood carries newly absorbed nutrients and water to the liver.

d) Blood circulates cells and chemicals that carry out immune functions.

e) Blood delivers clotting factors and WBCs that aid in hemostasis when skin is damaged

Answer:

b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.

Explanation:

Options a, c, d, e are all true statements about the contributions of the cardiovascular system to other body systems except option b which states that “Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs”.

Actually, the cardiovascular system works together with the respiratory system to supply oxygen to body tissues as blood is circulated in the body, while carbon dioxide is removed from the body at the lungs. In order words, carbon dioxide is removed, while oxygen is picked up as blood is transported through the capillaries of the lungs.
