IPSPs are the result of:
a. decreasing membrane conductance to sodium
b. decreasing membrane conductance to potassium
c. inhibitory neurotransmitter entering the postsynaptic cell
d. neurotransmitter binding to ligand-gated ion channels that are chloride selective
Answer:
d. neurotransmitter binding to ligand-gated ion channels that are chloride selective
Explanation:
IPSP refers to inhibitory postsynaptic potential (IPSP). It occurs when the neurotransmitters released from the axon terminals of the presynaptic neurons bind to and open the chloride ion channels. This allows the entry of chloride ions into the neuron making the inside of the membrane even more negative. This does not allow firing of the action potential. The postsynaptic neuron is said to be hyperpolarized. Therefore, IPSP results from hyperpolarization of postsynaptic neurons by the opening of ion channels such as chloride channels.
Answer: homeostasis.
Homeostasis is the regulation of the functions of some internal conditions as reaction to changes in the environment.
For example, although the external temparuture changes the matabolism is capable to keep the temperauture of the body constants through homeostasis.
That does not happen with the cold blooded animals. If you put a small frog very close to a hot ligthed bulb, its blood will not be able to keep it cool and it will dry completely.
Answer:
D
Explanation:
Males have testes while females have ovaries
They contain Chlorophyll so the answer would be D! Hope this helps! ^-^
Answer:
Explanation:
The melting point is the temperature at which any substance melts i.e changes its state from solid to liquid.
Melting is a phase change from solid to liquid.
- Melting point is a temperature value or number.
- Melting is phase change from solid to liquid.
- Melting usually occurs when temperature is added to a body.
- The melting point of all pure samples of a compound is the same as it is an intensive property.
- Melting is physical change of matter.
