Why is reabsorption important

Answers

Answer 1

Answer: The purpose of the kidneys is to filter waste from the blood, and other things like water, glucose, amino acids, some minerals/vitamins, and other small molecules can also get filtered out. Reabsorbtion of water in the kidneys allows the body to maintain a fluid balance (drink a lot and you pee more cause you have an excess of water). As for the other aforementioned things, they're often needed for metabolic processes (such as certain enzyme functions) so loosing it to waste decreases efficiency and efficacy of other bodily processes.

Which is a characteristic of all waves?All waves carry energy.
All waves move through space.
All waves move through matter, from particle to particle.
All waves transfer energy parallel to the direction of wave motion.

Answers

A) All waves carry energy

B and C cannot be correct, as some waves travel through space and some through matter, so this is not a characteristic of ALL waves. D cannot be correct either, as again not all waves move in the same ways. Hope this helps!

A property that is common to all waves is that all waves carry energy.

A wave is a disturbance along a medium which transmits energy. A wave is classified based on the direction of wave motion or based on the medium through which the wave is propagated. These two classifications of waves helps us to describe waves easily.

The properties of waves depends on whether the waves are mechanical or electromagnetic waves. However, a property that is common to all waves is that all waves carry energy.

Therefore, a common property to waves is that they all carry energy.

Genetics is the study of genes, genetic variation, and heredity in living organisms. It is generally considered a field of biology, but it intersects frequently with many of the life sciences and is strongly linked with the study of information systems. hope this helps:)

Because the flow speed in your capillaries is much less than in the aorta, the total cross-section area of the capillaries considered together must be much larger than that of the aorta. Given the flow speeds noted, the total area of the capillaries considered together is equivalent to the cross-section area of a single vessel of approximately what diameter

Answers

Answer:

Diameter of capillaries is 30-40 µm in diameter while on the other hand, the diameter of aorta is 4 cm.

Explanation:

The diameter of capillaries is 30-40 µm in diameter while on the other hand, the diameter of aorta is 4 cm which is the main reason for higher flow speed of the blood in the aorta as well as more blood is transported in the aorta. If the total area of the capillaries considered together is equivalent to the cross-section area of a single vessel of aorta then the flow speed of both is similar due to similar area.

Final answer:

The total cross-sectional area of the capillaries considered together must be much larger than that of the aorta to allow for a slow and controlled exchange of substances between the blood and the cells. The blood velocity in the aorta is about 25 cm/s, while in the capillaries, it is about 1 mm/s. We can use the equation A = πr^2 to find the cross-sectional area of a single capillary with a velocity of 1 mm/s.

Explanation:

The total cross-sectional area of the capillaries considered together must be much larger than that of the aorta because the flow speed in the capillaries is much less than in the aorta. This allows for a slow and controlled exchange of substances between the blood and the cells in the capillaries. The blood velocity in the aorta is about 25 cm/s, while in the capillaries, it is about 1 mm/s. If we assume the capillaries have a cylindrical shape, we can use the equation A = πr^2 to find the cross-sectional area of a single capillary with a velocity of 1 mm/s.
