Answer:
c)polymerase chain reaction (PCR).
Explanation:
Because the paleontologist recovered only a bit of tissue and it is very old, it is very likely that the DNA in the sample is very small and part of it is degraded. Anyway, the paleontologist must first amplify the DNA sample to obtain many identical copies of the specific region of the DNA they want to compare. the above is done through a polymerase chain reaction (PCR).
Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.
Answer:
Gamma-aminobutyric acid (GABA)
Explanation:
Gamma-aminobutyric acid (GABA) is the inhibitory neurotransmitter found in the central nervous system of mammals, especially humans, which is responsible for the regulation of communication between the brain cells, and also implicated in the slowing down of signals as neuronal impulses is reduced when it is activated. This is mostly responsible for the extreme uninhibited behaviors often associated with large alcohol consumption.
True. Anabolism builds complex molecules from simpler ones, while catabolism breaks large molecules into smaller ones.
