Evaluate hoe the heart can be compored to a mechanical pump

1 answer:

5 0

The main way in which the heart can be compared to a mechanical pump is that both of these things push liquid (blood in the case of the heart) through pipes (arteries in the case of the heart).

Answer:

The preferable words for the fill in the blanks will be -

afferent, efferent;

blood plasma;

diffusion (passive transport), active transport;

microvilli;

secretion;

urine output, cellular metabolism, diet;

1-1.8;

Urochrome;

urea, uric acid, creatinine;

vaporization, lungs, perspiration, skin, decreases;

dialysis.

Explanation:

The glomerulus is a unique high-pressure capillary bed because the afferent arteriole feeding it is larger in diameter than the efferent arteriole draining the bed.

Glomerular filtrate is very similar to blood plasma, but it has fewer proteins.

Mechanisms of tubular reabsorption include diffusion (passive transport) and active transport.

As an aid for the reabsorption process, the cells of the PCT have dense microvilli on their luminal surface, which increases surface area dramatically.

Other than reabsorption and important tubule function is secretion, which is important for ridding the body of substances not already in the filtrate.

Blood composition depends on urine output, cellular metabolism, and diet.

In a day's time, 180 liters of blood plasma is filtered into the kidney tubules, but only about 1-1.8 liters of urine is actually produced.

Urochrome is responsible for the normal yellow coloration of urine.

The three major nitrogenous wastes found in the blood, which must be disposed of, are urea, uric acid, and creatinine.

When water loss via vaporization from the lungs, or perspiration from the skin is excessive, urine output decreases.

If the kidneys become nonfunctional, dialysis is used to cleanse the blood of impurities.

How does the transcription of structural genes in an inducible operon occur? (A) It occurs continuously in the cell. (B) It star

-BARSIC- [3]

The transcription of structural genes in an inducible operon occur (B) It starts when the pathway's substrate is present.

Inducible operon is the one which works only when the stimulus is received by an inducer, enhancer or a positive regulator. Inducible operon consists of one or more structural genes. The example of inducible operon is lac operon.

Substrate is a chemical substance upon which any enzyme acts. It is a starting material for any process to begin. In operons as well, substrate acts as an inducer for beginning the process of transcription. In lac operon, lactose itself acts as a substrate for the transcription of the m-RNA coding for enzyme β-galactosidase.
