Explanation: The egg is a cell that is used to reproduce. It is the very beginning of what will become the embryo and eventually the baby. The sperm fertilizes the egg and contributes 50% of the embryo DNA to the ova (the other 50% of DNA comes from the egg, however sperm only contributes DNA to the egg during the fertilization process whereas the egg has a much more important role). The sperm and egg meet, the egg becomes fertilized and loaded with the DNA it needs to form. The egg provides nutrients needed for the embryo to grow until it is fully gestated.
I think the correct answer is C. Less than 10% of rain falls in a dry desert. Desert biomes are known to be the driest of all types of biomes. It receives very or almost no rainfall. Precipitation in a dry desert is about 250 mm per year.
