The enzyme responsible for adding new nucleotides to a growing DNA chain during DNA replication is RNA polymerase

DNA polymerase

DNA ligase

DNA helicase

B. DNA polymerase

Explanation:

A is wrong because RNA polymerase is an enzyme that synthesizes RNA from a DNA template, doesn't add to DNA chain during DNA replication.

C is wrong because it is an enzyme that joins DNA strands together by catalyzing the formation of a phosphodiester bond.

D is wrong because it unwinds the double strand of DNA.

please give thanks :)

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
