In the heart, the valves are located between atria and ventricles and between ventricles and arteries (option D).
<h3>What are valves in the heart?</h3>
Valves are membranous partitions which permit the passage of the contents of a vessel or cavity in one direction, but stop or control the flow in the opposite direction.
Valves in the heart enforce a one-way blood flow through the heart and separate atria from ventricles, and ventricles from the large arteries that leave them.
The four valves in the heart and their location is as follows:
- tricuspid valve: located between the right atrium and the right ventricle
- pulmonary valve: located between the right ventricle and the pulmonary artery
- mitral valve: located between the left atrium and the left ventricle
- aortic valve: located between the left ventricle and the aorta.
The valves between the atria and ventricles are called atrioventricular valves or cuspid valves while those at the bases of the large vessels leaving the ventricles are called semilunar valves.
Therefore, it can be said that the valves of the heart are located between atria and ventricles and between ventricles and arteries.

Eukaryotic cells are usually larger and more complex than prokaryotic cells, making your answer to this question D.
let me know if you have any further questions

Correct answer is A hope this helps
Glycolysis is the first step of cellular respiration - the process comprised of series of reactions in which energy is extracted from glucose molecules. The process of glycolysis is almost same in all living organisms.
If we quickly overview the process of glycolysis, we see that it is a process of earning ATPs as a return on ATP investment, why?
- 2 ATP molecules are invested during the first or preparatory phase pf glycolysis.
- 2 ATP molecules are formed for each glyceraldehyde 3-phosphate molecule. Therefore, total four ATP molecules are produced.
- Other than ATP, 1 NADH + H+ is also produced for each molecule of glyceraldehyde 3-phosphate.
Therefore,total amount of 2 NADH and 4ATP molecules are produced.
But since, there was an investment of two ATPs during the preparatory phase of glycolysis. Therefore, a total of 4-2=2 ATPs is formed/ So it is like an earning on an investment.
Hope it help!
