Which of the following is a direct result of antidiuretic hormone?

ElenaW [278]

Answer: Option A.

Decreased urine volume.

Explanation:

The direct result of antidiuretic hormone is decreased urine volume because it is the hormone secreted by the hypothalamus of the the brain and stored pituitary gland which control blood pressure and make the kidneys to release less water, as little water is released by the kidneys, there will be little amount of urine produced.

This hormone reduce the urine volume or amount of urine produced.

Which of the following statement(s) is/are true regarding the adrenal glands' relationship with the autonomic nervous system?

Studentka2010 [4]

Answer:

The true statements regarding the adrenal glands' relationship with the autonomic nervous system are:

a. The adrenal cortex is an extension of the parasympathetic nervous system.

c. The adrenal glands are strictly nerve tissue.

d. The parasympathetic division stimulates the adrenal cortex to secrete glucocorticoids.

e. The adrenal medulla is penetrated by the fibers of the sympathetic nervous system.

Explanation:

The levels of the central nervous system which play important roles in influencing the autonomic nervous system include cerebral cortex, hypothalamus, brain stem, and spinal cord. Usually, epinephrine (adrenaline) and norepinephrine are released into the blood stem when stress or a threat occurs. This alert serves as a warning signal and defense system. The purpose is to maintain homeostasis.

1. Suppose the synthesis of an amino acid was accomplished by four enzymes encoded by four genes that formed an operon. Draw a m

vivado [14]

I have attached lac operon model having 4 genes. See attachment for better understanding.

Answer:

The Lac operon is controlled by two signals.

Initiation

Glucose and lactose concentrations control the initiation of transcription of the Lac operon through their effects on the Lac repressor protein and Cap.

Lactose absent (Repression)

When lactose is absent, the Lac repressor binds the Lac operator and shuts off expression of the operon.

Lactose present (Transcription)

Addition of lactose increases the intracellular concentration of a related compound, allolactose. allolactose binds to the Lac repressor, causing it to undergo a conformational change that releases its grip on the operator DNa.

Glucose absent (Repression)

When glucose is absent, cyclic aMp (red triangle) is produced by the cell and Cap binds to DNA.

Glucose present (Transcription)

LacZ, the first gene of the operon, encodes the enzyme b-galactosidase, which breaks down lactose to galactose and glucose.
