Describe how obsidian is created from a volcano.

Biology
1 answer:
Jet001 [13]3 years ago
4 0

Answer:

Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. Obsidian is produced when felsic lava extruded from a volcano cools rapidly with minimal crystal growth. ... The inhibition of atomic diffusion through this highly viscous lava explains the lack of crystal growth.

The question is incomplete as it does not have the options which are:

A. Merocrine gland

B. Apocrine gland

C. Salivary gland

D. Holocrine gland

Answer:

D. Holocrine gland

Explanation:

Exocrine glands are the organs or the subcellular structures which secrete a substance which is excreted out of the body.

The exocrine glands are different from the endocrine glands as their secreted products are released out of the body which is not in the case of endocrine glands.

The wax is secreted by the sebaceous glands by the production of cells that break along the base of the garland with substance into the ductal system by the exocrine glands called Holocrine glands.

Thus, Option-D is the correct answer.

Holocrine glands will release whole broken open cells into their ductal system. These cells contain the stores of substance to be released by the gland. This method of secretion requires frequent cell turnover and replacement.

Anton [14]

Answer:

<h2>Insulin glargine</h2>

Explanation:

In case of type 1 diabetes, the body does not produce sufficient insulin or produce no insulin. The body breaks down the carbohydrates into blood sugar that it uses for energy,  and insulin is a hormone that removes glucose from the bloodstream into the cells of the body.  

Insulin glargine is a long-acting insulin that  works approximately for 24 hours.

Insulin glargine is used to blood sugar control with diabetes patients.

Radda [10]

Answer:

Considering that homeostasis is restored in the patient, his blood pH range would return to normal levels (7.35-7.45), and his hydrogen ion concentration in the blood would normalize. The effect of normalizing the body by getting rid of excess hydrogen ions is achieved by concentrating these ions into the urine for expulsion, therefore increasing the pH levels of urine.

Explanation:

Acidosis is the condition wherein excessive acid build-up within the body causes the blood pH to become lower than normal (normal pH range 7.35-7.45). This may be due to an excessive loss of bicarbonate in the blood, also known as metabolic acidosis, or due to an impairment in the elimination of carbon dioxide in the blood from poor lung function, also known as respiratory acidosis. The body's natural response to acidosis is to increase the breathing rate to eliminate carbon dioxide in the blood, restoring the natural pH of the body.

In people with diabetes mellitus type I, the lack of insulin causes cells to breakdown fat aside from glucose as an energy source. This process produces ketones as a metabolic by-product for energy but also causes the body to be acidic. This is known as diabetic ketoacidosis.
