Answer:

C. Systemic arterioles respond to a decrease in PO₂ by dilating, but pulmonary arterioles constrict in response to decreased PO₂.

Explanation:

In the arterioles, vasoconstriction is a response to high oxygen while vasodilation is a response to carbon dioxide and low pH. However, in the pulmonary arterioles, vasoconstriction occurs as a response to low oxygen and this mechanism is called hypoxic pulmonary vasoconstriction (HPV).

Which of the diagrams shows red blood cells in 0.0 M Solution​
Julli [10]

The rigth answer is the picture 4.

In the case of a hypotonic extracellular medium, there will be a large inflow of water to dilute the Na, thereby increasing the cell volume and there will be an explosion of the membrane in places so hemolysis, the contents of the red cell ( Hemoglobin) is released into the blood plasma.

On the other hand, in the case where the extracellular medium is hypertonic, therefore archi concentrated, well it will be the water of the red cell that will come out without damaging the membrane, we will rather have a red cell that is completely flat and non-functional without release. erythrocyte (Hb) content.

Can someone please help me
Usimov [2.4K]

Answer:

1A - Respiratory = trachea, lungs... however both arteries and veins move oxygen around the body, and are therefore valid answers

1B - Skeletal = bones

1C - Muscular = muscles

1D - Digestive = stomach, large/small intestine

1E - Circulatory = heart, veins and arteries

2. Cellular respiration is the conversion of sugar into energy the cell uses to function via various chemical reactions. Digestion is an example of this. Stomach acid breaks down food into sugars that cells break down further into energy to keep you alive

3. Bones contain bone marrow deep inside of them which is responsible for the creation of red blood cells. Your lungs can move air all they want but would be useless without red blood cells to take the oxygen to cells and take the CO2 away from them.
