Answer:
gene flow
Explanation:
Gene flow, in simple terms, is a transfer of gene from one population to another. Also called as migration, where there is movement of individuals, and the genetic material they carry from one population to another. It also involves successful breeding of these individuals in their new locations. When people with sickle cell anemia were brought into the US, transfer of the gene responsible for sickle cell disease changed the frequency of the sickle cell allele in overall US population.
The right answer is 20 aminoacids per second.
Transcription is a mechanism for synthesizing RNA from DNA.
Translation is a mechanism for synthesizing a polypeptide sequence from mRNA by converting the nucleotide triplet (codons) to amino acids.
So if one amino acid corresponds to three nucleotides. The polypeptide synthesis rate should be 20 amino acids per second for 60 nucleotides per second.
3 nucleotides ==> 1 amino acid
60 nucleotides ==> 60/3 = 20 amino acids.
Answer:
b. The water molecule is polar.
Explanation:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.
Answer: I think that it would be C because blooms are due to eutrophication, which means that there are high levels of phosphate in the water. Phosphate is a main ingredient in pesticides, which can run-off into rivers.
