After examining the fossil record, scientists have determined that scorpions today are much smaller than their extinct ancestors
BabaBlast [244]

Answer: C. scorpions have changed as a result of natural selection

Explanation:

The text tells us that scorpions today are now smaller than they were in the past. This means that the scorpions have changed since then i.e. they have evolved.

The primary reason for evolution is natural selection which refers to a situation whereby only the organisms that are better adapted in their species survive.

The conclusion that can be drawn from this research therefore is that we have smaller scorpions today because they stood a better chance of survival than the larger ones and so survived whilst the larger ones died out.

"the medulla, the pons, and the cerebellum are three main parts of the ______."
MA_775_DIABLO [31]

The medulla, pons, and the cerebellum are three main parts of the hindbrain.

Brain is the centre of the nervous system. It is enclosed in the skull cranium. The primary regions of the brain are the forebrain, midbrain and the hindbrain. The forebrain consists of the cerebrum and diencephalon. The midbrain is a small tubular region between the forebrain and the hindbrain. The hindbrain is made up of the medulla oblongata, pons and cerebellum.

Cerebellum is the second largest portion of the brain which helps in maintaining the body's equillibrium, coordinates muscular movements and body posture. Pons is the structure located in the brain stem which relays impulses from medulla to cerebellum and vice versa. Medulla oblongata is the lowest part of the brain stem controlling involuntary reflexes and has the respiratory and cardiac centres in it controlling respiration and heart beats respectively.
