Homework Answers
Actually the process of fertilization is not a one step or single phase process it is a multi phase process and in this processes many proteins as well as enzymes are involved and all this happens invivo in a cascade process.
Now if we can imagine the complexity of this multi-phase cascade process we can clearly realize that this process can not be properly understand from out side.
Another most important part is that the participating cells the male and female gamete (sperm & egg) both are so tiny that er need microscope to visualize them.
So in this scenario it is really difficult to understand what sperm and egg proteins are interacting during membrane fusion of mammalian fertilization.

In the wild, various sperm and egg cells must navigate a complex environment to complete fertilization. There are mechanisms in place at the molecular level to guard against interspecies fertilization, even between very closely related species. Some of these mechanisms involve lock and key functions of interacting proteins. These molecules most likely regulate which type of reproductive isolation mechanism? Please explain. Describe an example of non-heritable variation. Think about the way an organism interacts with its environment and how that...

1. When you look at a pine or maple tree, the plant you see is a _____. 2. The Brazil nut tree, Bertholletia excels (n = 17), is native to tropical rain forests of South America. It is a hardwood tree that can grow to over 50 meters tall, is a source of high-quality lumber, and is a favorite nesting site for harpy eagles. As the rainy season ends, tough-walled fruits, each containing 8-25 seeds (Brazil nuts), fall to the...
