To ensure genetic continuity during cellular growth and repair, dna makes exact copies of itself through what process?
a) duplication
b) replication
c) transcription
d) translation

Answer : The correct answer is -

B) Replication.

DNA replication is a mechanism of formation of two DNA molecules by using single molecule of DNA ( which is double stranded).

In this process, two strands of original DNA are first separated and act like template strand, using which enzyme DNA polymerase adds dNTPs ( deoxyribonucleoside triphosphate) in the direction 5' to 3', which is antiparallel to the direction of template strand.

By making exact copy of itself (through replication) , DNA ensures genetic continuity during cell growth and repair.

Thus, option B) is the right answer.

youre right there are

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
