Answer:
True
Explanation:
When the resting potential of the membrane is changed, the membrane becomes either more negative inside or less negative. This small deviation from the resting potential is called graded potential. A graded potential occurs when a stimulus triggers opening or closing of the mechanically gated or ligand-gated channels present in the plasma membrane.
For example, the presynaptic neuron releases neurotransmitters in response to a nerve impulse. The neurotransmitter binds to receptors present in the plasma membrane of the postsynaptic neuron and triggers the opening of the ion channels to allow the inflow of particular ions to flow. The flow of ions changes the voltage across the membrane. This change in membrane voltage is a postsynaptic potential and is a type of graded potential.

Answer:
uaa
Explanation:
An anticodon is a trinucleotide sequence localized in the transport RNA (tRNA) that binds via complementary base pairing to the codon in the messenger RNA (mRNA) during protein synthesis (translation). Thus, the tRNA anticodon binds with its complementary three-letter mRNA codon during translation in order to add a specific amino acid to the growing protein. Generally, the anticodon sequence positions 34–36-nt of the tRNA that reads its cognate mRNA codon sequence via Watson–Crick base pairing.
If Dr. Taylor's CVA had occurred in the same region of the right cerebral hemisphere, the thing that would have been different about her symptoms is the cerebral cortex. The cerebral cortex is said to be an essential part of our brain or the most important part of our brains.
Answer:
Friedrich Miescher discovered nucleic acids in blood cells.
Nuclein was discovered by Friedrich Miescher in 1869
Explanation
In the somewhat early 1880s Albert Kossel further purified the substance and discovered its highly acidic properties. Then he later discovered the nucleobases. In 1889 Richard Altman creates the term nucleic acid. Friedrich Miescher was the first scientist to ever isolate nucleic acid.
