Answer:
Y is probably excitatory and Z is probably inhibitory
Explanation:
- Two neurons communicate with each other generally by releasing neurotransmitters.
- The neuron which releases the neurotransmitter is termed as presynaptic neuron and the neuron to which the neurotransmitter binds to exert its effects is called as postsynaptic neuron.
- Based on the nature of the neurotransmitter released, the presynaptic neurons can either be inhibitory or excitatory in nature.
- The change in the membrane potential of the postsynaptic neurons depends on the total sum of inputs coming from different pre synaptic neurons at a given time.
- From the given situation, the stimulation by X alone is causing deploarization of 0.5 mV which shows that it is causing excitation, and since depolarization is increasing when X and Y are stimulaneously stimulated Y is also excitatory in nature. However the depolarisation is not occurring when X and Z are stimualted together and hence, Z is probably inhibitory in nature.
Answer:I think they would die from not doing anything.
A. It encloses the cytoplasm
He is WRONG
Explanation:
Any atom at the ground state has its orbital levels fill from the bottom (close to the nucleus) – up. The inner orbitals are of lower energy state and fill first because the atoms ‘likes’ to exist in the low energy and more stable state. Only when the atom is in an excited state do some of the electrons in the lower orbital levels shift to higher unfilled orbitals.
