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.——————Neurotransmitters are endogenous chemicals that enable neurotransmission. It is a type of chemical messenger which transmits signals across a chemical synapse, such as a neuromuscular junction, from one neuron (nerve cell) to another "target" neuron, muscle cell, or gland cell.
Answer:
B.) The amounts of A, T, G and C in DNA varies from species to species and C.) In any ome species, the amount of adenine closely approximates that of thymine D.) In any one species, the amount of guanine closely approximates that of cytosine
Genome
Explanation:
The genome of an organism is the summation of all the genes in the cells that hold information on how the organism is built and maintained. In higher organisms, the genome also contains non-coding regions that also play a significant role in the cells such as ensuring the integrity of chromosome ends. The genome of a human being is composed of approximately 3 billion base pairs.
The genome of organisms may not necessarily be found in the nucleus of cells, especially in eukaryotes, but in addition can be found even in membrane-bound organelles like the mitochondria and chloroplast.

Hi there!
In order to do fossil comparative anatomy and branching diagrams to explain the evolution of organism, scientists use <u>radiocarbonation </u><u>method</u>.
Explanation:
Carbon-14 can combine with oxygen in the atmosphere to create carbon dioxide, which is then absorbed by plants and makes its way through the food chain. The amount of carbon-14 in living plants and animals matches the amount in the atmosphere, but when plants and animals die, they no longer absorb carbon-14.
Because radiocarbon has a known rate of decay, the scientists can now determine about how long it has been since the plant or animal was alive. <u>The lower the amount of radiocarbon, the older the object.</u>
(Sometimes, C-12 is also used)
Answer:
action force. The push of the first object on the 2nd object. friction. A force that opposes the motion of an object.
