Answer:

Evidence for these geomagnetic reversals can be found in basalts, sediment cores taken from the ocean floors, and seafloor magnetic anomalies. Reversals occur nearly randomly in time, with intervals between reversals ranging from less than 0.1 million years to as much as 50 million years.

1. Why it is important to to have appropriate amounts of calcium in the body?
coldgirl [10]

Answer:

Almost all calcium in the body is stored in bones and teeth, giving them structure and hardness. Your body needs calcium for muscles to move and for nerves to carry messages between your brain and every part of your body.

Sodium-Potassium Pump

Three sodium ions bind to intracellular sites on the sodium-potassium pump.

A phosphate group is transferred to the pump via the hydrolysis of ATP.

The pump undergoes a conformational change, translocating sodium across the membrane.

FinnZ [79.3K]

Answer:

c. accidental removal of the parathyroid glands during surgery

Explanation:

Parathyroid gland is found closely situated at the back of the thyroid gland in the human neck region. Regulation of serum calcium levels in the body is a major function of the parathyroid gland through the secretion of a hormone called parathyroid hormone or parathormone.

During the surgery conducted to remove the thyroid gland, it is very likely that the parathyroid glands were accidentally damaged or removed. This most likely led to the non--secretion of parathormone, which is responsible for secretion of calcium in the body, when calcium levels drop.
