Destruction of the majority of the adrenal cortex would most likely result in decreased levels of ___________ and glucocorticoid

Alexus [3.1K]3 years ago

Answer:

Destruction of the majority of the adrenal cortex would most likely result in decreased levels of mineralocorticoids, sex corticoids and glucocorticoids.

Explanation:

Adrenal glands are conical pyramid shaped glands. A pair of glands present above each kidney. It has an outer adrenal cortex region and inner adrenal medulla. Cortex and medulla secrete different hormones and are also regulated in different ways.

Adrenal cortex has three layers:

a. Outer zona glomerulosa: secretes mineralocorticoids like aldosterone - regulates the metabolism of sodium and potassium.

b. Middle zona fasciculata: secretes glucocorticoids like cortisol - regulates the metabolism of carbohydrates, fats and proteins.

c. Inner zona reticularis: secretes sex corticoids like Androstenedione -  stimulates the development of external sexual characteristics in males.

In a condition called Addison's disease, major part of the adrenal cortex is destroyed which results in deficiency of both mineralocorticoids and glucocorticoids. Symptoms include bronze like pigmentation of skin, low BP, low plasma levels of Na+, high plasma levels of K+, nausea, vomiting and diarrhoea.

What is the term for a condition whereby small amounts of urine leak from a bladder that is always full as a result of a spinal
grigory [225]

Answer:

Overflow incontinence

Explanation:

Overflow incontinence is due to the leakage of small amounts of urine out of a bladder that is perpetually full. Diabetes and spinal cord injuries may trigger this kind of incontinence.

A spinal cord injury may disrupt interactions among the nerves in the spinal cord that regulates bladder and bowel function and the brain, which leads to incontinence.

This type of inconsistency results from Injury to the spinal cord at T10-L2 causing an overactive bladder.

What is a triacylglycerol ? Discuss the advantages of organisms having triacylglycerol as energy storage molecule?
Sergeeva-Olga [200]

Answer:

Triacylglycerols are acylglycerols with three fatty acid molecules, generally long chain, which can be the same or different; we speak of simple triacylglycerols when there is the same fatty acid in all three glycerol positions, but most are mixed triacylglycerols, with at least two different fatty acids. The properties of triacylglycerols will depend on the type of fatty acids they contain.

Most of the fats and oils of both animal origin (tallow, butter) and vegetable (olive, corn, sunflower, palm, and coconut oils) are formed almost exclusively by triacylglycerols.

Physiologically, triacylglycerols are an important energy reserve. In most eukaryotic cells, triacylglycerols are stored in the cytosol as microscopic fat droplets. In vertebrates there are specialized cells in the storage of fat, adipocytes. In humans, the presence of fatty tissue under the skin, in the abdominal cavity and in the mammary gland stands out.

Imagine that a mutation in DNA produces a protein with a slightly different amino acid sequence. how would this mutation affect
Lynna [10]

Answer:

It would most likely render the protein nonfunctional or mis-functional.

The mutation could result in three outcomes:

  1. Silent mutation, which changes the codon to the same amino acid. (AAA->AAG, both are lysine). But since the problem specified that it has a "slightly different amino acid sequence," we can assume this doesn't happen.
  2. Nonsense mutation, which changes a codon to a stop codon. This would end the chain of amino acids, making the protein potentially nonfunctional.
  3. Missense mutation, which changes a codon to another completely different codon. This can be harmful, as in sickle-cell disease, where just one amino acid, glutamic acid, is changed to valine.

How does composting influence resource availability?
ivanzaharov [21]

Answer:

Organic waste in landfills generates, methane, a potent greenhouse gas. By composting wasted food and other organics, methane emissions are significantly reduced. Compost reduces and in some cases eliminates the need for chemical fertilizers. Compost promotes higher yields of agricultural crops.
