Somatic mutations are important to the evolutionary process; most cancers result from somatic mutations : True
What is somatic mutations?
Any mutation that happens in a cell other than a gamete, germ cell, or gametocyte is referred to as a somatic mutation because it involves a change in the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells. Somatic mutations are typically not passed on to descendants, in contrast to germline mutations, which can be transmitted to an organism's offspring. Plants, which lack a separate germline, and animals that can reproduce asexually by processes like budding, as in the case of members of the cnidarian genus Hydra, obfuscate this distinction.
The descendants of a cell inside the same organism will all carry somatic mutations, even if somatic mutations are not passed on to an organism's progeny.

Answer:
4/13
Explanation:
If you are looking at a deck of cards, there are 52 cards in the deck. 13 cards per suit and there are 4 suits.
There are 3 face cards and a 10 in each suit. So in total there are 16 face cards and 10s.
So the probably of selecting a face card or a 10 is
16/52 reducing this would give you 4/13

-aminobutyric acid (GABA)</h2>
Glutamate is the primary excitatory transmitter in the central nervous system. Conversely, a major inhibitory transmitter is its derivative γ-aminobutyric acid (GABA), while another inhibitory neurotransmitter is the amino acid called glycine, which is mainly found in the spinal cord.
