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.

Answer:

This sample will absorb less energy because the more water, the harder it is to absorb all of the water. The other sample has less so the sand can absorb it more easily.

Answer:

Circulatory system remove waste from the cell and provide clean blood to the cell.

Explanation:

During cellular respiration, lungs inhale oxygen which stored in the alveoli. The red blood cells contains hemoglobin that carries deoxygenated blood containing carbondioxide from the cell in the veins to the heart and unload this carbondioxide gas in the alveoli of the lungs and load oxygenated blood having oxygen from the alveoli through capillaries in order to provide oxygen to the cells that is necessary for the survival of humans. Platelets are the type of cells that helps in blood clotting whereas white blood cells provides immunity against pathogens.
