Answer:
(Q1) An animal is born with a shorter tail. This makes no difference to its ability to survive or reproduce, but as a result of pure luck, the animal survives, reproduces, and passes its shorter tail down to its offspring. Over time, the species develops a shorter tail.
(Answer) genetic drift
(Q2) The process of altering the genome of one species by adding genes from another species in order to gain a beneficial trait is known as
(Answer) genetic modification.
(Q3) Some fish in a murky underground lake have lighter scales than the others. This makes it slightly harder for the lighter fish to escape detection by predators, but most light-colored fish live long enough to reproduce. A natural event separates the dark-scaled fish from their light-scaled cousins, and as a result, a new species of dark-scaled fish emerges.
(Answer) The fish experienced an evolutionary change because of genetic drift.
(Q4) Which scenario accurately describes an example of artificial selection?
(Answer) A farmer intentionally breeds oranges to be more resistant to aphids.
(Q5) Over many generations, there is a good chance that an advantageous gene will be shared by every organism of the same species or that a new species will emerge. These long-term outcomes are called
(Answer) evolution.
