Answers & explanation:

I - False

A sympatric speciation can occur commonly in both animals and plants. Sympatric speciation events are very common in plants because it is normal for them to develop multiple sets of chromosomes.

II - False

Sympatric speciation occurs without geographic variation. When two populations of the same species live in the same area but there is no crossing between populations, sympatric speciation occurs.

III - True

Sympatric species may indeed lead to the formation of new species. Sympatric speciation is believed to be responsible, for example, for the large number of cichlid fish species found in Lake Victoria on the African continent. According to research, this lake was colonized by only one ancestral species.

15. Slaivary glands are stimulated to release digestive enzymes by<br> and<br> of food.
slavikrds [6]

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
