Answer:
False
Explanation:
The hypotheses are conjectures, speculations, predictions about a certain phenomenon of nature and how it behaves. Hypotheses should be tested, which is usually accomplished through experiments.
Theories are well-founded explanations for describing events occurring in nature. They involve hypotheses already thoroughly tested, facts and laws.
Growth hormone is produced by the pituitary gland, a small gland like a bean, located in the lower part of the brain. As the name says, this hormone is absolutely essential for providing physical growth. However, this hormone also has an influence on the body's metabolism.
It was already known that GH is linked to bone development and height increase and is found in large quantities in muscles, liver, tissues and organs directly involved in growth metabolism. After some scientific studies and experiments, it was discovered that the brain is also full of receptors for this hormone.
Previously, leptin was believed to be the main hormone to work to conserve energy in cases of dietary limitations. When there is weight loss, circulating leptin levels in the bloodstream fall. Leptin is a hormone produced by the body's cells that store fat. When leptin levels start to lose fat, the levels drop a lot and the brain feels this drop and activates the hunger and energy saving mechanisms.

The phospholipid bilayer that makes up the plasma membrane has hydrophobic tails and polar heads that face each other to repel water.
The membrane that divides the inside of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and it is present in all cells.
A cell wall is affixed to the plasma membrane on the outside of both bacterial and plant cells. The plasma membrane is made up of lipids and proteins, much like every other cellular membrane.
Therefore, the phospholipid bilayer, which creates a permanent barrier between two aqueous compartments, is the membrane's basic structural component.
