Answer:-
In reaction to the smell, sight, or thought of food, the first hormonal response is that of salivation ( starts making saliva ) The salivary glands secrete more saliva in response to the stimulus presented by food in preparation for digestion. Simultaneously, the stomach begins to produce hydrocholoric acid to digest the food
The salivary glands are glands inside a person's mouth and throat that produce the watery and mucous-containing fluid known as saliva. Saliva is constantly released into our mouth to keep it lubricated and to help us chew and swallow food. There are three pairs of salivary glands: sublingual, parotid and submaxillary
and for the end the main digestive enzymes in your body are : -
1- Amylase, produced in the mouth. It helps break down large starch molecules into smaller sugar molecules.
2- Pepsin, produced in the stomach. Pepsin helps break down proteins into amino acids.
3- Trypsin, produced in the pancreas. Trypsin also breaks down proteins
4- Pancreatic lipase, produced in the pancreas. It is used to break apart fats.
5- Deoxyribonuclease and ribonuclease, produced in the pancreas. They are enzymes that break bonds in nucleic acids like DNA and RNA
The right answer is He is studying oxygen, which can also be found in proteins.
Carbon atoms could also be a right answer if there was a statement...
Sugars, composed only of carbon atoms, hydrogen, and oxygen, are the simplest energetic nutrients. Example to (C6H12O6): If we look at the chemical formula for glucose, we can see that the proportion Hydrogen / Oxygen corresponds to that of water (H2O)
Lipids also consist of carbon atoms (C), hydrogen (H) and oxygen (O), but fatty acids are molecules that are low in oxygen. Example: Linoleic acid C18H32O2
C. A nucleotide base is the polymer of nucleic acids, such as DNA. A gene is the sequence of many nucleic acids and a genome is an organisms full set of genetic info.

Answer:
The correct sequence will be:
1. Action potential arrives at axon terminal.
2. Voltage-gated calcium channels open.
3. Neurotransmitter released into synaptic cleft.
4. Neurotransmitter binds to receptors.
5. Graded potential generated in postsynaptic cell.
6. Neurotransmitter is removed from the synaptic cleft.
Explanation:
The nerve impulses transmission takes place at the junction known as a synapse. At the synapse, the impulse in the form of action potential reaches at the end of the axon terminal also known as the synaptic knob of the presynaptic neuron.
This action potential results in the opening of the voltage-gated calcium channels in the membrane which leads to the influx or inside movement of the calcium ions.
These calcium ions bind to the neurotransmitters which help in the release of the neurotransmitters in the synaptic cleft. The released neurotransmitter binds to the ligand-gated receptors in the membrane of the postsynaptic membrane which leads to the opening of sodium channels.
Due to the influx of sodium ions in the post-synaptic neuron causes depolarization of the neuron and the potential is generated in the neuron.
Thus, the marked sequence is correct.
