Even though there are no choices given in this particular question, the principle of osmosis is very easy to understand.
When we talk about osmosis, we are referring to the movement of water from a low concentration to a higher concentration. This is different from diffusion, which talks specifically about the movement of <em>solutes</em> in the solution (from a higher concentration to a lower concentration.)
When an RBC is placed inside a <em>hypertonic </em>solution, the water inside the RBC will go out thereby shrinking the RBC.
Inside an <em>isotonic</em> solution, the RBC will remain the same because the concentrations are equal.
Inside a <em>hypotonic</em> solution, the RBC will lyse or explode because water will move from the solution going inside the RBC.
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.
Because you might have just done something different with the experiment and messed up someway during the test
Answer:
D. Microglia
Explanation:
Microglia are phagocytic, which means that they are cells that can engulf other cells and particles. Microglia protect the CNS by engulfing foreign particles and bacteria. They act also as a clean-up crew that help remove dead cells. They are found in both the brain and spinal cord, which make up the Central Nervous System, or the CNS.
