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:
The offspring will show the dominant trait 100% if it has the dominant allele in its genotype (ex. Rr and RR will always exhibit the dominant trait or phenotype).
Explanation:
A:) In cellular respiration, the carbohydrates from food are disassembled into glucose molecules. Then, this glucose is used to produce energy-rich ATP molecules. In most eukaryotic organisms, cellular respiration takes place in the mitochondria of cells.
He recognized and named Oxygen as well as hydrogen.
As motion accelerates it produces heat, as heat of an object increases or decreases, affects its potential to be moved
