People in living in areas with steep mountains actually has an advantage when it comes to agriculture because there is already a free and vacant space that can be used to plant crops. In order to develop thesemountains into an area where planting is easily done, the people can create a stair-like structure on the edges of the mountains where they can plant crops that will be used daily and even sold in the market. This practice will be a very good strategy to make use of the steep mountain which is the only available natural resource at the time.<span>

Answer:
The correct option is b) motor output of the spinal cord
Explanation:
Motor neurons, also called afferent neurons, drive impulses from the brain and spinal cord to the receptors (eg, muscles). They are the motor output component of the spinal cord.
The spinal cord is a cord of nerve tissue that runs inside the spine. It conducts the nerve impulses that arrive from the receptors to the brain, and the responses with the motor orders from the brain to the effector organs. Thus, the brain receives the information and can develop an order that modifies the reflex response given by the spinal cord. A spinal nerve has two nerve roots: a motor and a sensory root. The motor root has nerve fibers that carry signals from the spinal cord, to the muscles to stimulate contraction and produce muscle movements, the fibers are efferent as they leave the medulla to the periphery through the anterior roots of the spinal nerves.
The answer is; C
It is caused by the recessive allele because the parents appear normal but are carriers of the disorder (meaning they are heterozygous for Pseudohypertrophic muscular dystrophy). Only when the offspring is heterogenous recessive do they display the disorder.
The disorder is also sex-linked because it tends to affect only boys. This means that the disorder is probably coded for by alleles in the Y- chromosome that determines the male sex.
