Answer:
Pass information by generating electric signals
Explanation:
Neurons are the fundamental unit of the nervous system. Neurons send information across the body through generation of electric signals called as action potential. There are basically three types of neurons
a) Sensory neurons which carry information from the sense organs in the form of impulse to the central nervous system (CNS)
b) Motor neurons – These carry information from the CNS to the body parts such as sense organs, muscles etc.
c) Interneurons – They are connecting neurons which are responsible for transferring information from one neuron to the other neuron.
Answer:
Option a
Explanation:
Random selection or random sampling from a given population is the most appropriate way, especially in experimental studies. This method is simple and accurate. According to the above-mentioned case, if the researcher selects students randomly for the experimental and control group, then each of them would have an equal chance of selection. Hence, the results would be generalized and not biased.
Answer: D
Reactants are the compounds on the left hand side of the equation where the arrow represents, the reaction from the reactants to the products. Therefore the products are the result on the right hand side. Therefore the answer is D

Well first off, Adaptation, evolution and variation are all causes of natural selection. Which leaves overpopulation.
Therefore overpopulation would be the least likely cause of natural selection.
