For the same insolation, order these regions from "highest absorption to lowest."
son4ous [18]
Insolation is the amount of solar energy that is incident on the surface of the earth. For the same insolation, water bodies tend to absorb the most heat as water has a high heat capacity and so do grasslands. Areas such as desserts and glaciers do not absorb high amounts of insolation due to which these areas exhibit extreme, inhabitable environments. The order becomes:

What is the elevation of point B
Alika [10]

Answer: c. Point B has an elevation less than 2750 feet.

Explanation:

The lines drawn on the map are known as contour lines and they are used to measure elevation. Point B is on a river and rivers are only able to flow at a lower elevation than the area around them.

Point B is therefore lower than the area around it and as the closest contour line to it puts the area at an elevation of 2,750 feet, that must mean that Point B is lower than 2,750 feet.

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.
