Answer:

The connection is the common ancestors.

Explanation:

As shown in the question above, Darwin's work generated a map where the lines and forks created an image similar to a tree.

This "tree" linked species and places studied by Darwin. This connection was established by a common connection to all the species that Darwin studied. This connection was the common ancestor that a set of species shared and that was essential for the evolution of species to be understood.

geniusboy [140]

Answer:

c) receptor; control center; effector.

Explanation:

Homeostasis maintains the internal body conditions almost constant. It includes specific cells that sense any deviations of internal or external conditions from the normal range. These cells are called receptors. The sensory information from the receptors is delivered to the control center. The central nervous system mainly serves as a control system wherein sensory information from the receptors is processed. The control center commands muscles and/or glands to perform desired responses to restore the homeostasis. Here, muscles and glands serve as effectors.

For example, thermoreceptors sense the rise of body temperature and the brain (control center) commands sweat glands (effectors) to produce sweat.

Answer:

Neurons.

Explanation:

The nervous system is one of the most important system of the body that coordinates and maintains the other system of the body. The nervous is divided into two main parts -  peripheral nervous system and central nervous system.

Neuron is the structural and the functional unit of the nervous system. The nervous system contains the million of neuron that conducts the information from one part of the body to another. They are held together by the glial cells also know as glue and travels communication through the long distances.

Thus, the answer is neurons.
