The right option is; A. Accumulation of lactic acid in the muscles of her limbs

Accumulation of lactic acid in the muscles of her limbs is the reason for this.

During strenuous exercise when the body requires high energy due to insufficient supply of oxygen, the body generates energy anaerobically and there is formation and accumulation of lactate (lactic acid) in the muscle. High lactate levels in the muscle increase the acidity of the muscle cells, and it also cause the disruptions of other metabolites. This result in feelings of painful sensation and soreness in active muscles.

A mistake in DNA replication, in which the wrong base is placed in the growing DNA strand, can have profound effects on the desc
Klio2033 [76]

Answer:

DNA replication is the process in which the DNA is copied and it occurs during synthesis phase of the eukaryotic cell cycle. It begins with an enzyme breaking the bonds between complementary bases in DNA which exposes the bases inside  the molecules so they can be read by another enzyme and used to build two new DNA strands with complementary bases.

Explanation:

The original strand is: TAGCGTT

                                      ATCGCAA

The Mutated strand is: TGGCGTT

                                       ATCGCAA

<em>The replicated strand is: GAATCAC</em>

<em>                                           CTTAGTG</em>

Andrew [12]

Answer:

Fur color that closely matches the eucalyptus bark color

Explanation:

In terms of evolving from land dwellers to tree dwellers, the number of offspring does not matter. Although the ability to run faster is a good evolution for escaping predators, it does not help the koalas evolve to be better tree dwellers (how would you run using only the trees?). Communicating with their peers would be convenient for survival, but it does not help koalas become better tree dwellers. What does help koalas survive better by traveling through the trees is camouflaging with the bark of the tree to hide from predators.
