Answer:
it could help the seed of it has enough soil and Sunshine
False.
Any time a scientific theory is challenged, it means it's not a good
theory. And this statement is not valid. In theoretical models, they are
revisited when there are further studies and discoveries found in a certain
area where they can be remodeled and reintegrated instead of disregarding its
credibility. Models, theories and paradigms are not challenged but rather
encouraged, they are supported in many studies since these theories and models
were created in order for us to understand a certain phenomenon but it would
likely help the scientific society to be updated in the new forms or spheres of
improvement rather than discouragement.
Answer:
The correct answer is option A. "The contents of blood come into closer contact with tissues in a closed system than an open system".
Explanation:
In a closed circulatory system, the blood has an specific path, circulating from arteries to veins and to smaller blood vessels throughout the body. This is in contrast with open circulatory systems at which the blood is not contained in arteries or veins but it suffuses the body. A closed circulatory system have many advantages over open circulatory system, however in a closed circulatory system the contents of blood are not into closer contact with tissues in than an open system. Actually, in an open circulatory system the blood is in closer contact with tissues.
Answer:
A. An organism's traits
Explanation:
Proteins do much of the chemical work inside cells, so they largely determine what those traits are.
Cellular respiration occurs in the mitochondria, the double membrane organelle. It occurs when the cells need energy, storage molecules like glycogen are rapidly broken down from being a polysaccharide to its monomer units which undergo reactions once transported to the cells requiring energy and broken down to release its energy.
Yes, there is a situation where living cells are not respiring. For example in the microbial cell that lives in anaerobic environments in specific environments will use fermentation instead of respiration to produce ATP. The example of this is the yeast cells in beer mash.
