Answer:
When red blood cells are placed inside pure water they normally swell up and eventually explode. Red blood cells in pure water swell up because the pure water enter in the red blood cells by mean of osmosis. The water molecules are able to enter the red blood cells because the salt concentration inside the red blood cells is more than that of the pure water.
As water continue to move inside the cells, the cell swell up and eventually burst because the internal pressure inside the cell is greater than the external pressure, therefore the cell membrane become ruptured and eventually burst.
Answer:
c) degree of myelination of the axon
Explanation:
Axon conduction velocity can be defined as the speed at which an electrochemical impulse propagates down an axon.
Factors that determines the rate of conduction velocity are:
- axon diameter-larger diameter axons have a higher conduction velocity
- sheeth-a myelin sheath increases the rate of impulse propagatio
Different types of neurons will have different speed of propagation because of their different properties and because different types of information are sent.
Answer:
the correct answer is c i just tuck the text
Explanation:
A. True
variation of reproduction produces diverse life forms and allows organisms to evolve complex characteristics over billions of years.
Adenine and thymine are complementary bases, as well as cytosine and guanine. Complementary bases bind always with each other, and never with another base. Cytosine and guanine are joined together by 3 hydrogen bonds and thymine with adenine with 2 hydrogen bonds
