Answer:
Phospholipid bilayer.
Explanation:
The plasma membrane (also known as the cell membrane or cytoplasmic membrane) is defined as a biological membrane that separates the interiors of a cell from its external environment.
The plasma membrane has a function that protects the cell from its external environment, mediates cellular transport, and transmits cellular signals.
It is composed of a lipids bilayer (phospholipids and cholesterol), (phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group) with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules which hence, regulates the movement of substances in and out of cells. Plasma membranes is very flexible in order to allow cells change form example, red blood cells change shape as they pass through narrow capillaries.
If you want to see something in fine detail, you should focus the light the cornea. The lens works together with the cornea to focus light correctly on retina.
When light hit on retina special cells called photo receptors turn the light into electrical signals. The lens are the clear part of eyes behind the iris that help to focus light and image on retina to see something clearly.Lens is the important part of eye when it comes to focusing light so that we can see perfect clear image.
The retina is the most sensitive part which can effect by more light because retina convert incoming light into electrical impulse.

The part of the cns sent a signal to help prevent Jamal's fall was the cerebellum
<h3>How does the cerebellum act in balance?</h3>
Balance and posture are the responsibility of the cerebellum, which coordinates body movements, uniting and articulating muscle movements so that they keep the body balanced and maintain its posture.
With this information, we can conclude that the part of the cns sent a signal to help prevent Jamal's fall was the cerebellum

Skeleton is what the connective tissue uses to stay part of the body. Without the skeletal system we wouldn't be able to move our muscles.
