Answer:
1. cerebellum
2. brainstem
3. cerebrum
4. cerebrum
5. brainstem
6. cerebrum
7. cerebellum
Explanation:
The cerebellum is a region of the brain located behind the top part of the brainstem, which coordinates voluntary movements (e.g., posture, balance, coordination, speech). The cerebellum is well known to regulate the balance of the body. The brainstem is a type of automatic control center that connects the cerebrum with the spinal cord. The pons represents a group of nerves that serve as connection between the cerebrum and cerebellum. The pons are located in the brainstem (between the midbrain and the<em> medulla oblongata</em>). The cerebrum is the largest part of the brain and can be divided into right and left hemispheres. These hemispheres communicate with each other by the <em>corpus callosum</em>.

Answer:
d. Some individuals are better adapted to the environment
Explanation:
Kettlewell’s biological experiment, which was conducted in England, was to study the evolutionary changes taking place in trees in relation to the appearance of dark-colored moth.
It was observed that white moths were more common before the industrial revolution. After the industrial revolution, which changed the background of the environment of the moths due to pollution, the moths became easily seen and obvious to predatory birds.
It was discovered that peppered moths were selectively preyed on by birds depending on their body color, which serves as the most important factor that determines if moths can survive predation by blending with the background of their environment. This led to the evolving of moths of their color to blend with the background of their environment, which makes them hide from the birds that prey on them.
Kettlewell was trying to verify the factor in evolution by natural selection, which says, “some individuals are better adapted to the environment”.
