In the nervous system a synapse is a structure that permits a neuron or nerve cell to pass an electrical or chemical signal to another neuron or to the target effector cell
The layers and structures the needle passed through are- epidermis, dermis, subcutaneous layer or hypodermis, connective tissue layer and muscle.
The epidermis is the outermost layer of the three layers that make up the skin, the inner layers being the dermis and hypodermis. The connective tissues connects, binds and separates other tissues or organs. Muscles are soft tissues found in the body. They function to produce force and motion.
The statement that best summarizes Darwin's theory of natural selection is D. Organisms best suited to their environment will survive and reproduce. This is becasue let's say some giraffes have short necks and some long necks and their food is leaves on high trees then the long necked giraffes will survive over short necked giraffes because short necked giraffes can't reach for their food and eventually there will be only long necked giraffes left and they will reproduce with other long necked giraffes and make long necked giraffes.
