Having two copies of the mutated genes cause sickle cell anemia, but having just one copy does not, and can actually protect against malaria - an example of how mutations are sometimes beneficial.
The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.
Hope this helped :)
The spiral usually begins with an increase in demand. The direct effect of this increase is that the producers (of commodities) raise prices to continue to make a profit. It usually begins with a rise in production costs.
Pieces of genes can be inserted into the genetic material of prokaryotes so that they will make the protein products encoded in the genes or copies of the genes themselves
If scientists wanted to learn more about evolutionary history, they would study all but one of these molecules. The biological molecule that would NOT offermuch information about the history of life is
<span>phospholipids
</span>the DNA proteins and nucleic acid will give them alot of information about history of life
so correct option is D
hope it helps
