Which of the following statements does not support the conclusion that giraffes are k-selected species?
Trava [24]

The correct answer is C. Newborn giraffes are capable of coordinated walking within an hour of birth, and running within 24 hours of birth.

Explanation:

In biology, k-selected species are species that have stable populations although they do not give birth to multiple offspring at once and individual offspring are mainly big animals that require more time to mature this makes parents invest more time and effort in them to guarantee they survive. According to this, giraffes can be classified as k-selected species because they usually have limited offspring (Giraffes rarely give birth to twins), they seem to mature slowly and offspring requires more care and time (giraffes begin mating at 6-7 years of age) and they are large when they are born (Giraffes are approximately 6’ tall and weigh 150 lbs at birth).

However, the fact "Newborn giraffes are capable of coordinated walking within an hour of birth, and running within 24 hours of birth" does not support the idea these animals are k-select species because this shows rapid maturation and little time and effort invested which is the opposite to k-selected species.

Which is an advantage of genetic engineering?
lys-0071 [83]
<span>Great minds combined with technological advancements have a lead to creations and achievements that would have been impossible. Whatever great scientist of the past has achieved have already been surpassed or improved through modern and innovative ideas and processes. An excellent example of which is the direct manipulation of an organism’s DNA, also known as genetic engineering or genetic modification (GM). Coming from the terms genes and modify, the entire process is something out of a science fiction movie. Well, it used to be that way until the practice was perfected and used in actual applications. Genetic engineering made it possible to add new DNA or alter bad ones.</span>
