The cohesion-tension model works like this: Transpiration (evaporation) occurs because stomata in the leaves are open to allow gas exchange for photosynthesis.

Explanation

Parathyroid hormone (PTH) is produced and secreted by the parathyroid glands, which are located behind the thyroid gland in the neck.

PTH regulates blood calcium levels by stimulating"

• bone cells (osteoclasts) to release calcium from bones
• increasing calcium absorption in the intestines
• reducing calcium excretion in the kidneys.

72 beats per minute is a good heart rate.

Complete answer:

The resting person usually has a pulse rate between 70 (beats per minute) and 80 (beats per minute).

Your risk of dying from a heart attack is lower if your heart rate is below 80 beats per minute.

A normal resting heart rate ranges from 60 to 100 beats per minute.
