C.
The skeletal system provides structure to the human body.
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.
Answer:
D
Explanation:
D is the only option where the cause of the pollution is not something man-made.
When Charles Darwin considered wings of birds, apart from his famous proposal he also predicted that fossils will be found with structures that are intermediate between early and modern form.
Answer: Option C
<u>Explanation:</u>
Charles Darwin was basically referring to transitional Fossil while considering Wings of bird. So what are transitional fossil? They are the fossil remains of both the ancestral group and the descendant group.
Since we don’t have enough record of the fossils, it is very difficult to know the accuracy of transitional fossil. However, we do have some record of fossils from which we can gather enough evidence of how the fossils where earlier and how it evolved over a period of time.

Explanation:
A classification or division essay groups objects, people, or events into categories by the characteristics that they share. Usually the writer begins with a group of people or things and then separates them into subgroups or types. There are a several steps to writing an effective division or classification essay.
