Answer:
A. Where does sugar enter the blood?
After eating food, in the intestine the glucosa is absorbed by an SGLT1 cotransporter who releases it to the bloodstream.
B. How can you tell where sugar enters the blood?
Making an analysis of its high concentration in the epithelial cells of the intestine
C. Where is sugar removed from the blood?
After traveling through the blood flow, the sugar enters the cells of the body that require it, for example, muscle cells. Excess glucose in the blood is removed by the kidney through urine.
D. How can you tell?
The filtration of glucose by the kidneys can be verified by an analysis of their co-concentrations in these renal cells and Medical tests of the urine sample.
Answer:
analogous trait
Explanation:
Analogous traits or structures are the ones that develop as a result of convergent evolution between the distantly related species. The members of these species develop the same features to become adapted to similar environmental conditions. These analogous traits are not present in their ancestors. For example, bats and insects have wings to assist them in flying. However, the wings in bats and insects have a different basic structure.
Answer:
The correct answer is: As ventricular systole start, the AV valves are closed and the semilunar valves are closed. Because the ventricles are contracting and both valves are closed, pressure increases rapidly leading to ejection.
Explanation:
The heart functions like a bomb that pumps blood to every part of the body, which is fundamental for the proper function of every organ.
The cardiac cycle has two main phases: the diastole and the systole. During the diastole, blood returns from the body through the vena cava and is deposited in the right atrium of the heart. When the pressure in the right atrium becomes bigger than the pressure in the right ventricle, the tricuspid valve opens and the blood flows to the left atrium.
During systole, the atria suffer a depolarization that makes the atria's muscle contract. Thanks to this, the blood goes through the atria to the ventricles.
During isovolumetric contraction, the ventricles contract but the pulmonary and aortic valves remain closed. When the ventricular muscle contracts, the semilunar valves open.
