Answer:
Hyperpolarization
Explanation:
At the synapse, neurotransmitters bind to neurotransmitter receptors in the postsynaptic neuron’s plasma membrane. This results in the opening of the ions channels and the flow of specific ions to change the voltage across the membrane. An inhibitory neurotransmitter inhibits the firing of the action potential by making the inside of the membrane more negative. It is called hyperpolarization (inhibition).
It may occur when the neurotransmitter opens the Cl– or K+ channels to allow the movement of chloride ions into the cell while permitting the outward movement of potassium ions to make the inside of the cell more negative.
Answer:
Certainly more than that.
Explanation:
Answer:
(1) Red Blood Cell
(2) Enzymes
Explanation:
(1) Oxygenated Red Blood cells transport oxygen from the lungs through the body using the arteries as a channel of movement to all organs.
(2) Enzymes are proteins that catalyze chemical reaction in the digestion of food so as to break food down into a form which can be absorbed by the body.
The answer is D, sweating.
Homeostasis is where the body uses some mechanisms to maintain a optimum condition for the body to function. These conditions may include body temperature, blood glucose level etc.
Sweating is a mechanism that can help maintain the body temperature. During hot conditions, the sweat glands under the skin surface may produce sweat, which is then released to the skin surface. When the sweat is on the skin surface, they evaporate. During evaporation, heat energy is brought away from the skin as the sweat molecules that have a higher kinetic energy (=temperature) escaped from the sweat drop. The average temperature of the sweat is reduced. Eventually, the temperature of the body is decreased and this help maintain the suitable temperature for the body to function.
Therefore, your answer is D, sweating.
