They help pump blood at a greater distance than Atria can.
Answer:
a. True, b. False, c.True, d. True
Explanation:
a. Base excision repair is started by a DNA glycosylase that recognizes the changes and removes the altered base by cleavage of the glycosidic bond binding the base and the deoxyribose sugar together.
b. Nucleotide excision repair works by a cut-and patch mechanism that removes their heavy lesions, including pyrimidine dimers and nucleotides . Endonucleases are responsible for the lesion of the damaged strand.
c. Nucleotide excision repair is initiated by the proteins namely UvrA, UvrC, and UvrB in Escherichia coli.
-UvrD (helicase II) later removes the damaged strand
-DNA polymerase I (PolI) fills in the resulting gap.
d. DNA glycolases removes the damaged nitrogenous base.
-It leaves the sugar-phosphate backbone intact and thus creating an apurinic/apyrimidinic site, which is commonly referred to as an AP site.
e. Xeroderma pigmentosum complementation group A(XPA)
-This is an essential protein in the nucleotide excision repair pathway.
- It helps to make a pre-incision complex along with other proteins.
The correct answer is letter C. evaporation in the area will decrease. When humans remove vegetation from an area, the water cycle is MOST directly affected on the evaporation side. The evaporation in that area will decrease because there'll be no more plants that will hasten the evaporation process. This will create an abnormality in the water cycle.
In clockwise hemisphere would you find this motion. As shown in picture the arrow is facing toward the south to north east direction.
<h3>
In which direction earth rotates?</h3>
Earth rotation direction is west to east, that appears counterclockwise when viewed from above the North Pole.
Any circle drawn around the earth divides it into two equal halves called hemispheres. There are four hemisphere northern, southern, western, eastern hemisphere on the earth.
