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.
Can you identify what your wanting here like are you meaning an example of cytoplasm are things that you can touch as an example
Answer:
The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. These processes define the two major phases of the cell cycle.
Explanation:
I believe it is B.
Don’t hate me if I am wrong :,)
Answer: Option C..
controls autonomic nervous system and regulates thirst
Explanation:
Hypothalamus controls autonomic nervous system and regulates thirst because it is above the brain stem and it receive autonomic regulatory signals or information , then it then act to integrate and controls autonomic nervous system. The autonomic nervous system help to regulate different types of body functions like sexual arousal, heart rate, pupilatory rate, digestion rate , respiratory rate e.t.c.
