Psychologists use statistics to assist them in analyzing data, and also to give more precise measurements to describe whether something is statistically significant. Analyzing data using statistics enables researchers to find patterns, make claims, and share their results with others.
When a nerve impulse reaches the end of the first neuron (presynaptic terminal), various neurotransmitters are released from the same, into the area between the two neurons, called as a synaptic cleft. From synaptic cleft, these neurotransmitters are picked up the postsynaptic terminal of the second neuron, which leads to an impulse.
Desity=V/M so you would divide 12.0 by 6 and you would get 2.
The answer is 2.
Tissues
Tissues are somewhat more complex units than cells. By definition, a tissue is an organization of a great many similar cells with varying amounts and kinds of nonliving, intercellular substance between them.
