Answer: Option D
Explanation:
Hershey and Chase were the scientist that concluded that DNA is the genetic material which is transferred from one generation to another generation.
Before their experiment, people used to believe that protein is the genetic material.
Hershey and Chase conducted an experiment on bacteriophage where Radioactive phosphrous was transferred along with DNA in the cell.
This proved that DNA is the genetic material that transferred information from one generation to another.
Radiation. radiation is what causes heat, therefore the air would heat from the natural radiation.
I believe carbon dating does work to determine the age of the earth but, the answer might be <u>D</u>. Let me know if it was right.
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.
