Survival of the fittest definition biology
olya-2409 [2.1K]

Answer:

"Survival of the fittest" is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. The biological concept of fitness is defined as reproductive success.

Explanation:

The Darwinian evolutionary theory was created by Charles Darwin.

Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species, overcoming scientific rejection of earlier concepts of transmutation of species. By the 1870s, the scientific community and a majority of the educated public had accepted evolution as a fact.

How does the enzyme telomerase meet the challenge of replicating the ends of linear chromosomes?
maxonik [38]

Answer:

The correct answer is C) It catalyzes the lengthening of telomeres, compensating for the shortening that could occur during replication without telomerase activity.

Explanation:

While replicating, the ends of the chromosomes always lose a part of the ends, therefore, the telomerase catalyzes this growing process, somehow compensating the information that will be lost.
