The answer is TRUE ( if your doing the true or false thing)
The answer would be: <span>A. Mitochondrial DNA is beneficial in both of these cases
</span>
Mitochondrial DNA or mtDNA is DNA that found in the mitochondrial. Mitochondrial DNA only inherited from mother, so it's relatively unchanged than nuclear DNA that mixed from father and mother.
Mitochondrial DNA has higher mutation rate in animals because it doesn't have repair mechanism like nuclear DNA. These mutations can be used as a clue for how close the relation of an organism to others.
This makes analyzing the ancestral relationship of organisms that closely or distantly related easier.
#1. Typical United States weather patterns show the continental polar air mass moving south toward the Gulf of Mexico. Why does this air mass movement happen?
C) The polar air mass moves south to replace the rising maritime tropical air mass.
#2. Running a mineral across a porcelain plate to see the color it leaves behind on the plate may be described as testing for D) streak.
#3. D. Carbonization preserves soft tissues of plants or animals as a thin carbon film, usually in fine-grained shale sediments.
#4. We can divide natural resources into two basic categories: renewable and nonrenewable. Consider the bar graph of resource usage. If we wanted to reduce the use of nonrenewable natural resources, it would be least important to A) reduce deforestation.
#5. Nicolaus Copernicus was a Polish astronomer who is best known for the theory that the sun is near the center of the universe and that the earth and other planets revolve around it. Copernicus did not believe that the planets were influenced by or revolved due to the sun; instead he believed that the sun was located near the center of the universe and that it was this center which influenced those bodies and caused them to revolve. When this theory was first published, the scientific community did not accept it. Which reason BEST explains the reason for rejection of this theory?
C) It lacked sufficient evidence and explanation.
Hope I helped!!
The trp repressor blocks transcription of the trp operon (B) when the repressor binds to tryptophan.
trp operon or the tryptophan operon codes enzymes for the amino acid tryptophan. The operon is on when the tryptophan is low in amount whereas the operon is off when the tryptophan is low in amount. The operon is an assimilation of five genes.
Repressor is a small protein that is supposed to prevent the synthesis of proteins. It does so binding to the operator gene. Therefore, presence or absence of repressor is a determining factor for an operon to be on or off.
