With sexual reproduction a sperm coming from the male must unite with the female egg. Both are needed for this kind of reproduction, and an offspring CAN'T be formed without both. Unlike asexual reproduction, the offspring of a mammal reproducing sexually is DIFFERENT from both parents, since the offspring is a combination of both the mother and the father.
An easy to remember example I use when thinking about what sexual reproduction is:
the formation of a human child. A mother with her egg and the father with the sperm is BOTH needed. If you think about siblings that come from the same parents (and therefore same gene pool) they are not all exactly identical to each other. Although they may have similar features, they look different and are NOT genetically identical
Therefor for your question the answer is D.

Answer:
C. Large, deep body of water that contains fresh water
Explanation:
Keywords in question: "Freshwater wetland"
Answer A does not have those keywords in the answer. It does not talk about water, it talks about acidic areas!
Answer B does talk about water, but it's not specifically saying anything about freshwater. It talks more about the landscape of the area feeding water into rivers.
Answer C says fresh water at the end of the answer. It's telling you that the body of water contains fresh water. So, this phrase does describe the qualities of fresh water wetland.

Answer:
The most important information in this model he developed is the "filter theory."
Explanation:
Filter theory is a description of desirability planned by Kerchoff and Davies (1962). This concept proposes that individuals advance associations by smearing a sequence of filters, such as resemblance of communal demographic issues and arrogance and complementary of wants to slender down the pool of obtainable candidates. Filter theory is a sociological theory concerning dating and mate selection. It proposes that social structure limits the number of eligible candidates for a mate. Most often, this takes place due to homogamy, as people seek to date and marry only those similar to them.
