The answer is 3. both of the parents have these dominant genes
The main signal in small intestine for pancreatic bicarbonate ion secretion is Secretin.
When food from the stomach with acidic medium enters duodenum(first part of small intestine) it stimulates the lining of duodenum cells to release the hormone secretin.
This hormone travels via bloodstream to pancreas and stimulate to it to release bicarbonate ions.Now these ions enter duodenum and neutralise the acidic medium.
This results in the optimum pH for the enzymatic action to take place thereby promoting final digestion of protein.
The population of beetle will increasingly become green, with subsequent generations, until it becomes the dominant phenotype. This is because the green beetles will be able to camouflage with their environment and avoid being preyed on by the birds as compared to the black beetles. Therefore, the green beetle will have a high chance of reaching the reproductive stage and passing its genes to the next generation as compared to the black beetle.
Space is filled with nothing.
Space is the absence of matter.
Hope this helped
