DNA being placed with DNA polymerase and nucleotides and resulting in new copies is not an opinion or inference because the fact is, new more DNA was found in the test tube after adding the enzymes and nucleotides than before the addition. DNA sequencing of the new copies would have shown that the sequences of the new DNA are identical to the original DNA that was first placed in the test tube. Also, other experiments would have shown that adding other different kinds of molecules or enzymes does not, in fact, produce new strands of the original DNA, nor should it be able replicate the DNA at all.

Answer:

The clue refers to solid data as it was directly witnessed from the experiment. The scientist actually witnessed this data. There was no need for the scientist to make any opinions regarding the information or presume and infer that what would have taken place as he actually witnessed this happening. He witnessed that when DNA was extracted from the cell and was subjected to a test tube with nucleotides and polymerase, the original DNA gets copied.

Do you think that the terms “closest evolutionary relationship” and “most common ancestor” used when describing the relationship
tatyana61 [14]

Answer:

<em>Yes, the above terms will be much similar.</em>

Explanation:

The term 'closest evolutionary relationship' reflects the organism or species which were the closest to different species in a phylogeny.

Most common ancestor also describes the ancestor from which two different organisms might have evolved.

Both the terms 'closest evolutionary relationship' and 'most common ancestor' show the common ancestors in a phylogenetic lineage. Hence, on evolutionary levels, both these terms have similar meanings and are often used to describe phylogenetic lineages.

GABA is the primary neurotransmitter that underlies synaptic inhibition. GABA mostly
WARRIOR [948]

Answer:

b. brings the postsynaptic cell to the chloride equilibrium potential  

Explanation:

Gamma-aminobutyric acid (GABA) is one of the most important neurotransmitters, chemicals that brain cells use to communicate with each other. In fact, it is the most frequent inhibitory neurotransmitter. Inhibiting neurotransmitters decrease the chances that a nerve impulse will be triggered.

The main function of GABA as an inhibitory neurotransmitter is to slow down brain activity. It is also involved in vision, sleep, muscle tone and motor control.

It is widely distributed both inside and outside the central nervous system. It is found in the intestines, stomach, bladder, lungs, liver, skin, spleen, muscles, kidneys, pancreas and reproductive organs.

In vertebrates, GABA leads the postsynaptic cell to the chloride equilibrium potential. Through it, chloride ions flow out of the cell to achieve equilibrium.
