Answer:
The main factor that causes vasoconstriction is the high concentration calcium inside muscle cells.
Explanation:
When the vessels suffer vasoconstriction, the blood supply is decreased and in this way the heat of the body is maintained. The way this happens is because the blood can no longer reach the surface and therefore decreases outward heat radiation. The main factor that causes vasoconstriction is the high concentration calcium inside muscle cells. There are several factors that cause vasoconstriction, internal or external. Environment is one of the external factors, and what happens to the penguins' feet is an example for it, since they are trying to preserve body heat to survive.
Molecules that have the same chemical formula but have different molecular structures are: Isomers.
Well if your question is meant to be like this hydrolysis is used to break apart complex sugars but on the other hand if your trying to make complex sugars this process is called Dehydration synthesis
Phenotype: Ww, ww
Genotype Ratio: 2/4, 50/50 or half and half
Answer:
a. the RNA polymerase undergoes abortive initiation prior to promoter clearance
Explanation:
In eukaryotes the 3' end of the mRNA is polyadenylated to protect the mRNA from degradation.
In eukaryotes, a modified guanine cap is added to the 5' end of the mRNAd to protects the transcript from being broken down.
Most bacterial RNA transcripts do not undergo splicing.
The nucleosome is the basic unit of chromatin repeat in eukaryotes.
