Answer:
Yes, our body is made up of four Macromolecules.
Explanation:
Yes, the claim of the student is right that Macromolecules such as carbohydrates, lipids, proteins, and nucleic acids makeup the human body because all the cells are made up of carbohydrates, lipids, proteins, and nucleic acids. We know that our body is made up of cells so we can say that our body is made up of four Macromolecules. For example, our muscles are made up of protein, the fats present in our body are the lipids, carbohydrates are stored in the form of glycogen In liver and nucleic acids are present in the form of DNA and RNA.
Answer:
1.
Explanation:
Atomic mass is protons+neutrons. Atomic number is just protons.
The postsynaptic potential is the membrane potential, which takes place in the neuron present post synapsis (after the chemical synapse). The presynaptic neuron releases neurotransmitter, which causes the firing in the postsynaptic neurons.
The firing of the post synaptic neuron depends on the excitation and inhibition inputs received from the presynaptic neuron. The firing is the resultant of the summation of excitatory and inhibitory potential. In case, the excitatory potential is greater than inhibitory potential, the post synaptic neuron would be excited. in case, inhibitory potential is greater than excitatory potential, then the post synaptic neuron would be inhibited.
Hence, the correct answer is option d.
