A classic example of selection in natural populations involves the peppered moth Biston betularia in England. Industrial gases k

illed the lichens and mosses on buildings, trees, etc., and soot deposited on the landscape. Dark-colored moths gained a selective advantage. In this case, one would say that there was selection against the light-colored moths. Which morph, light or dark, would have the highest fitness? (Enter light or dark in the box below.)

Answer:

Dark colored moth

Explanation:

Moths either dark or light live on the bark of the trees. During industrial revolution in England, excessive pollution caused the darkening of bark of trees. Due to this environmental change, some of the light colored moths evolved and turned into dark colored moths. Both bark and moth being dark in color, made the moths untraceable by their predators. While the light colored moths on dark trees were easily recognizable by their predators.

Hence, the dark colored moths possess high fitness.

Nonamiya [84]

Answer:

The cell bodies of sensory neurons that are in clusters of neurons outside the spinal cord are called  ____

The answer is "dorsal root ganglia"

Explanation:

Explanations of some terms

Sensory neurons:

Sensory neurons, also known as afferent neurons, have cell bodies that are located in the dorsal ganglia (also known as  spinal ganglia) of the spinal cord. Most sensory neurons have one axon which is split into two branches, they transmit impulses toward the spinal cord.

Spinal cord:

The spinal cord is a tubular structure composed of nervous tissue housed within the vertebral column, runs from the base of the brain to the lower spine. Spinal cord is a component of the Central Nervous System that serves as information highway the between brain and the body which Integrates and processes information. It can function with the brain and can also function independently of the brain.

Dorsal root ganglia:

Dorsal root ganglia also known as dorsal ganglia originated as bipolar cells. They exists within the peripheral nervous system and they have special nerve cell clusters that aid in transmitting the sensory messages of pain and touch. The dorsal root ganglia receive information from sensory receptor organs and transmitting the information to the central nervous system.
