Answer: The postsynaptic cells has many synapses with many presynaptic neuron.
Synapse can be defined as a structure that
allow neuron to send a chemical or electrical signal to another neuron.
However, postsynaptic potential is a temporary change in the electrical
polarization of the membrane of a nerve cell and they are known to be receiver
of neurotransmitter message.
Answer : An atom with 7 protons, 6 neutrons,
and 7 electrons has an atomic mass of 13 amu.
Explanation:
As we are give that,
Number of protons
7
Number of electrons =7
Number of neutrons =6
As we know that,
Atomic number =Number of protons = Number
of electrons =7
Atomic mass = Number of neutrons + Atomic
number
Atomic mass = 6 + 7 = 13 amu
Therefore, the atomic mass is, 13 amu
As humans plants also need oxygen to breathe they only take in carbon dioxide to do photosynthesis.So they wont do photosynthesis at night and so they only need to breathe. even though their stomata are closed at night some oxygen can go inside. and this is how plants breathe when their stomata are … Enzymes change carbon dioxide to glucose.
