The answer is molecules can be saturated and it has no rings
and only single bonds, or they may be unsaturated and can contain the rings or
multiple bonds. Unsaturation is the element of rings and multiple bonds. We should remember that saturated
hydrocarbons have two times the number of carbons (N) plus two hydrogen atoms
in them (2N +2).

I think that they look towards the rain forests because there is always new or similar species with in the forests. They might need to see if they can find more to the species and see if they are going extinct. They would do anything to help the plants and animals survive and populate.
How many chapters are in part 1 then I can assist you!
Seeing that our species is constantly evolving, maybe it is starting to get more uncomfortable to walk on all fours.
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.
