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:
Force of repulsion.
By decreasing distance and increasing charge on both objects.
Explanation:
Force of repulsion is present between two negatively charged objects due to their same charge. if both charges are opposite to one another so it exerts force of attraction on one another. If we decrease the distance between two negatively charged objects so they exerts more force of repulsion on one another or by increasing power of charge on both objects also increases force on one another.
The question is incorrect. The correct question is as follows:
Nerve cells, the basic elements of the nervous system, have a cell body that contains a nucleus. Physically held in place by glial cells. They have the ability to communicate with other cells and transmit information across relatively long distances
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.
