Answer:
D
Explanation:
Bone marrow contains stems cells which then turn into immature blood cells and they mature there. kinda like a school for young blood cells. they also make white blood cells and platelets.
Answer:
So this is just a guess but i think its D but like I said its a guess.
The given statements can be matched as following:
a)The diffusion of water from a high concentration to a low concentration - Osmosis
b)Lowers the amount of energy needed to perform chemical reactions
- Enzymes
c)When you breath O2 passes into your blood stream while CO2 passes out of your blood stream
-Simple Diffusion
d)Involved with, but does not become a part of chemical reactions
-Enzymes
e)Small molecules with no charge can move through semi-permeable membranes by this process-
Simple Diffusion
Explanation:
a) Osmosis is generally defined as the process by which water is transported from a region of Higher concentration to the region of Lower concentration.
b) Enzymes are well known to reduce the amount of energy required or needed for a chemical reaction to take place.
c)The process by which oxygen passes through our blood stream and carbondioxide passes through the other is known as simple diffusion process.
d) Enzymes are ones that actively gets involved in the chemical reaction but they will never become a part of that chemical reaction.
e) Diffusion is the process by which very small molecules that carries no charge moves through semi permeable membrane.
The correct answer is option (D) The active transport and the facilitated diffusion both involve the proteins present in the cell membrane.
Facilitated diffusion transport the large and the charged molecules through the protein transport channels present in the cell membrane. In this case, the solute move from a region of higher concentration to lower concentration and it does not require energy.
Active transports takes place when the molecules move from a region of lower concentration to higher concentration via the membrane protein channels.
Both facilitated diffusion and active transport requires the proteins present in the cell membrane.
