Biology

Answer:

D - Its genetic diversity is very low

Explanation:

An extinction vortex can be defined as the process which populations in decline pass through to drive them into a vortex of smaller populations, endangering their survival as they tread the path to extinction.

Populations that fall to extinction vortex already have small populations which is usually as a result of certain powerful genetic factors, which cause the populations to continue to decline in size.

During genetic drift which occurs in all populations, small populations tend to lose genetic diversity as a result of the random nature of gamete sampling.

This is because any change in alleles in a small populations can have dastardly effects on the populations size due to a small gene pool.

siniylev [52]

Answer:

Spinous process

Explanation:

The rhomboideus minor muscle originates on the <u>spinous processes</u> of vertebrae T2-T5

The rhomboideus minor muscle forms part of the superficial group of back muscles. The muscles in the superficial group are immediately deep to the skin and superficial fascia. They attach the superior part of the appendicular skeleton (clavicle, scapula, and humerus) to the axial skeleton (skull, ribs, and vertebral column).

These muscles are sometimes referred to as the appendicular group, since they are primarily involved with movements of part of the appendicular skeleton.

The rhomboideus minor is located deep to the trapezius in the superior part of the back. It inserts on the medial border of the scapula, is innervated by the dorsal scapular nerve its function is to adduct and elevate the scapula.

What letter represents summer where you live?
AURORKA [14]

I live in letter D in summer and letter B in winter.

<h3><u>Explanation:</u></h3>

In the diagram the letter D represents the summer solstice and the letter B represents the winter solstice. But the letter A and C represents the equinoxes that are present in the month of March and September. Here in India the country lies above tropic of Cancer. So the condition here is like the temperate region. So during summer the sun's rays directly fall on the country as well as during winter the country receives oblique sun rays. Thus from the diagram we can see see that the letter B represents the condition of earth when the sun's rays are not directly falling on earth. So it's winter solstice .

In the letter D we can see that the earth is going through the summer solstice because sun's rays are directly falling on the earth. So it's summer at that time.

Natasha_Volkova [10]
Known as the cell’s “command center,” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information. Within the nucleus is a smaller structure called the nucleolus, which houses the RNA (ribonucleic acid). RNA helps convey the DNA’s orders to the rest of the cell and serves as a template for protein synthesis.
