Answer:
D. Enzymes open the DNA strand, remove a segment of DNA from the strand that contains the damage, and resynthesize the correct DNA sequence.
Explanation:
From time to time, the DNA gets exposed to certain chemicals or radiation that damages it. However, the cell has a DNA repair mechanism in place called NUCLEOTIDE EXCISION REPAIR (NER).
NUCLEOTIDE EXCISION REPAIR (NER) is one of the DNA repair mechanisms in which certain enzymes open the DNA strand, remove a segment of DNA that contains the damaged gene or nucleotide bases, and resynthesize the correct DNA sequence using the pair of the damaged one.
Answer:
A compound contains atoms of different elements chemically combined together in a fixed ratio. A mixture is a combination of two or more substances where there is no chemical combination or reaction. ... Mixtures contain different elements and compounds but the ratio is not fixed nor are they combined via chemical bonds.
Explanation:
Potassium is just below the sodium in periodic table in s group !
so the valence electron of sodium and potassium is same and that is 1 !
Answer:
Along the Kuroshio Current, because it is carrying water north towards melting ice caps
Explanation:
The ocean currents have the tendency to be faster when they are warmer, and to be slower when they are colder. The reason for this is that the warmer water is less dense, thus it can move more quickly, while the colder water is denser, thus heavier, so it moves slower. The Kuroshio Current moves from the lower latitudes toward the higher latitudes. As it does, this ocean current is becoming colder and colder as it gets closer to the higher latitudes, so it is becoming denser, heavier, and because of it slower. Another thing that will contribute to this current's slowing down are the melting ice caps because of the climate change, as they will make the water even colder, and the Kuroshio Current will come across this cold water, so it will decrease its speed significantly.
i think its a hidden virus i hope this helps
