Answer:
<h2>C. A slow heart rate increases end diastolic volume, stroke volume, and force of contraction.</h2>
Explanation:
Cardiac output: The volume of blood the heart pumps via the circulatory system per minute is known as cardiac output.
Stroke volume : The volume of blood ejected by the left ventricle in one contraction is called or known as stroke volume and it with heart rate defines the cardiac output.
Cardiac output, is : A slow heart rate increases end diastolic volume, stroke volume, and force of contraction.
Answer:
Neil Shubin bases his argument that the anatomy of Tiktaalik is relevant to that of humans by discussing specific features of the anatomy of Tiktaalik that vary from typical fish anatomy and correspond to features of the human body. For example, he points out that Tiktaalik has a neck that is able to bend independently of the rest of the body, unlike fish, and like all terrestrial vertebrates, including humans. Therefore, the evolutionary history of humans can be traced to an organism similar to Tiktaalik, resulting in the concept of the "inner fish."

Explanation:
Food chain may be a linear sequence of transfer of energy when one organism is being eaten by another organism in an ecosystem. The transfer of energy are often explained by 10% law which states that energy decreases by 10% because it is being transferred from lower to subsequent higher trophic level. there's a limit to the amount of levels that a organic phenomenon can reach this is often due to the subsequent reasons:
1. a big amount of energy is lost thanks to the very fact that organisms undergoes respiration . This lost energy can't be reverted back. Hence, limits the quantity of energy being transferred to the upper trophic levels.
2. a number of the undigested waste is excreted by the organisms. This waste being the a part of biomass gets lost within the environment, which again limit the quantity of overall energy being transmitted to the upper trophic levels.
3. Not all organisms are consumed by other organisms belonging to the distinct trophic levels. a number of them might not survive or die.
Both is the process of cell division!
but in mitosis...2 cells are formed and meiosis 4 cells are formed !!!
<span> Gravitational forces are only attractive but electromagnetic forces are both attractive and repulsive.</span> Because magnetic force has negative and positive charges, it can be both attractive and repulsive. Gravity affects objects at a distance, but the attraction weakens as the objects get farther apart.
