Answer:
Approximately 20,500 genes
Explanation:
The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.
Answer:
a. similar environments and specific traits increased their chances of survival
Explanation:
I eliminated b because of the statement "caused exactly the same mutations." Considering that mutations are entirely random, this would be highly unlikely. Choice a. fits better with the concept of convergent evolution and natural selection. If they evolved in different environments, they would have adapted in diff. ways and thus had diff. body structures.
The alcoholic fermentation process is used to produce beer and wine.

Answer:
Explanation:
The crust below the oceans is thinner than the crust below that continents.
This crust is called oceanic crust. It is predominantly made up of mafic magma which produces basalt and other mafic rocks when they cool and solidify.
The oceanic crust is generally thinner than the continental crust below the continent.
The oceanic crust is about 5-10km thick.
Continental crust is about 30km thick.
In terms of density, the oceanic crust is denser than the continental crust.
