B) the selection for different shaped beaks that best suit different niches
Answer:
The correct answer would be phenotypic variation.
Phenotype refers to observable traits or characteristics of an individual. For example, height, color, shape, et cetera.
Phenotypic variation refers to the sum total of variations in characteristics within populations of the same species.
In contrast, genotypic variation refers to the sum total of variations (such as allele frequency) present in the genome of populations of the same species.
The hindbrain consists of the medulla, the pons, and the cerebellum.
<h3>The hindbrain</h3>
The hindbrain is the portion of the brain that is otherwise known as the rhombencephalon. It is the part of the brain that is located towards the lower back.
The hindbrain consists of 3 main parts:
- The medulla oblongata
- The pons
- The cerebellum
Each component has specific functions they perform. The medulla oblongata is located at the extreme end where the brain connects with the spinal cord. It controls activities such as heartbeat, blood pressure, and respiration.
The pons of the hindbrain work hand in hand with the medullar oblongata for effective breathing. In addition, it is the part of the brain that controls the circadian rhythm of the body.
The cerebellum helps the body to maintain postural balance and adjustments when necessary.
