Answer:

1) The structure shown is of a cell membrane. A cell membrane is made up of phospholipid bilayer. The head of the bilayer are made up of phophates and glycerol which are facing outward. The tail is made up of fatty acids which is enclosed in the layers. The cell membrane also comprises of cholesterol and membrane proteins.

2) The cell membrane is semi-permeable. It allows the entry of specific molecules into the cell and exit specific molecules only.

3) The cell membrane helps to regulate the specific entry of molecules into a cell. By doing so, it acts like a filter for the cell and allows the entry of those materials which are required by the cell.

4) Water moves through the cell membrane by osmosis. Osmosis can be described as the movement of water molecules from an area of higher concentration to an area of lower concentration along the concentration gradient.

Where do prions come from?
Musya8 [376]

Answer:

There are prion-like particles in the brain normally, and when these become abnormal they can cause disease. (Ans. A)

Explanation:

Prions are proteins which can trigger normal proteins to fold abnormally, and they are present in the brain. They are causing many types of neurodegenerative diseases in both humans and animals. Which are known as transmissible spongiform encephalopathies.

Prions can enter the brain with the help of infection, also can arise from the gene mutation that encodes the proteins, and sometimes this affects humans by infected meat.

If a person infected from prion disease, it affects central nervous system tissues like brain, eye tissues and spinal cord.
