Introduction:
The process of digestion is defined as the breaking down of complex substances consumed through the diet into smaller substances to get energy. The digested and absorbed nutrients are also stored in different forms in the body which can be used by the body later on. The undigested food is removed out of the body through the process of excretion. The digestion process starts in the mouth and every region of the gastrointestinal tract contributes to the whole process.
Answer to Problem 6A
Correct answer:
The correct answer is option (B) the duct leading from the liver and gallbladder is blocked.
Explanation of Solution
Explanation/justification for the correct answer:
Option (B) the duct leading from the liver and gallbladder is blocked. The digestion of fat majorly occurs in the small intestine and with the help of bile. Bile emulsifies the fat and thus assists in fat digestion. Bile juice is produced in the liver and is stored in the gallbladder. It is also transported from the liver directly into the small intestine through a duct connecting the liver, gall bladder, and intestine. Therefore any blockage in this duct may prevent the entry of bile in the intestine and thus fats will not be digested. So, the correct answer is option (B).
Explanation for incorrect answer:
Option (A) the sphincter at the bottom of the stomach is not allowing bile to pass into the small intestine. The digestion of fat majorly occurs in the small intestine and with the help of bile. Bile emulsifies the fat and thus assists in fat digestion. Bile juice is produced in the liver and is stored in the gallbladder. It is also transported from the liver directly into the small intestine through a duct connecting the liver, gall bladder, and intestine. The sphincter at the bottom of the stomach allows the passage of chyme and not for bile. So, this is an incorrect option.
Option (C) the person is secreting excess bile. The digestion of fat majorly occurs in the small intestine and with the help of bile. Bile emulsifies the fat and thus assists in fat digestion. Lack of bile results in the indigestion of fat but excess bile will lead to watery stool or diarrhea. So, this is an incorrect answer.
Option (D) the stomach is not acidic enough for the digestion of fats. The digestion of fat majorly occurs in the small intestine and with the help of bile. The acidity of the stomach and enzymes in the stomach majorly digests proteins and not fats. So, this is an incorrect answer.

Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…arrow_forwardQuestion #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:arrow_forward

Select your answers for both dose and interval. Hint: It may be helpful to think about this problem using an example such as food. How would you eat if you wanted to maintain very steady hunger/satiety levels without changing your total caloric intake? Options: A. Dose; Increase dose B. Dose; Decrease dose C.
