Answer:
See the answer below
Explanation:
For each heterozygous parent with the genotype BbRr, the possible gametes are: BR, Br, bR, and br. A set of these gametes from one of the parents will be lined up along the top of the Punnet's square while another set from the other parent will be lined up along the side of the square.
The result is shown in the attached image.
Answer:
<u><em>They take nutrients needed by healthy cells, and as they grow they interfere with the function of normal cells and organs.</em></u>
Explanation:
Many mutations can lead to the formation of cancer. Cancer can be described as an abnormal type of cell division of the cells of the body. As cancer cells are the cells of the body dividing abnormally, the immune cells fail to fight them. These cells keep on dividing and also disturb the functioning of the neighbouring cells and tissues. They even take up most of the nutrients required by normal body cells hence, being very toxic for the normal cells.
<span>An amphibian that lacks lungs and breathes entirely through its skin would have to be smaller than an amphibian with lungs so that the small oxygen intake correlates with
the small surface area of the amphibian. This would then allow it to breath efficiently.</span>
The percentage of the stroke volume is ejected during the first quarter of systole will be approximately 60% to 65%
<u>Explanation:</u>
The time interval between the atria contraction and the relaxation of ventricles are called as a Cardiac cycle. Systole denotes the heart contraction during the blood pumping. Diastole refers to the heart relaxation when the blood is filled in the heart chambers. The total blood is not fully pumped by the ventricles.
Instead they will pump only a proportion of blood in each of the cardiac cycle. The ejection fraction refers to the proportion of the intraventricular volume that is received as a output in circulation process. A human with normal heart functioning can have approximately 60-65%. This is known to be stroke volume. The blood volume that is ejected is strove volume.
Answer:
Many distance runners “carb load” the day before a big race. How does this eating strategy provide an advantage to the runner?
The carbohydrates cause the release of insulin.
The excess carbohydrates are converted to fats, which have a higher calorie density.
The glucose from the carbohydrates lets the muscles make excess ATP overnight.
The excess carbohydrates can be stored in the muscles as glycogen.
Explanation:
<em>During the exercise</em>, the energy is consumed in the form of glycogen that the liver provides, <em>there are evidences that maintain that the consumption of carbohydrates during prolonged sports improves fatigue resistance.
</em>
<em>
</em>
<em>During exercise</em>, carbohydrates stored as muscle glycogen are used as a specific energy source for muscle. In the liver, however, glycogen is converted by glycogenolysis into glucose, which passes into the blood and from it to the working muscles.
<u><em>The answer is</em></u>: <u>Excess carbohydrates can be stored in the muscles as glycogen.</u>
