14. a prokaryotic cell is being looked at under the microscope and a scientist is watching molecules such as sodium enter and exit the cell
what part of the prokaryotic cell is being looked at under the microscope?
o a. cell wall
b. plasma membrane
c. dna
d. cytoplastic membrane

ANSWER:

The part which is looked under the microscope is the plasma membrane.

EXPLANATION:

The plasma membrane is known as the cell membrane and protects the inter-cellular components from the external environment. The plasma membrane controls and regulates the material which enter and exit a cell.

The plasma membrane comprises of proteins, carbohydrates, and lipids and 'surrounds the cytoplasm of the cell'. The plasma membrane function is to maintain cell potential and helps the 'cytoskeleton' to provide a shape to the cell.  

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

b.have there own function.
