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.

A student made a model of a cell. First, she filled a clear plastic bag with gelatin.
Ksivusya [100]
B) the model does not show that cells can contain smaller structures inside.

This is true because only a rubber ball was added, indicating that only a nucleus or any one organelle is present in a cell. However, the cell contains more than one organelle from the nucleus, mitochondria, Golgi apparatus, smooth and rough endoplasmic reticulum, ribosomes, and more.

Another possible answer would be D since they model does not show the process of cellular respiration where cells undergo this process to create ATP in the mitochondria.
