Answer:
A. by reacting animal fat or vegetable oil with water.
D. by treating animal fat or vegetable oil with hydrogen
Explanation:
Water is insoluble in animal fat or vegetable oil so it makes a layer on the surface of oil. When animal fat or vegetable oil react with hydrogen, it produces solid oil called ghee not biofuels. Biofuel is produced when animal fat or vegetable oil react with alcohol.

DNA structure, function and replication. DNA is a long molecule that consists of two strands of nucleotides twisted together in a long spiral called a double helix, the base-pairing rules describe which bases pair together in a DNA double helix, work together to produce two identical copies of the original DNA molecule=DNA structure; DNA funcution; RNA; replication; transcription; translation; the two strands are wound round each other to form a double helix. The two strands. Are joined together by hydrogen bonds between the bases, before every cell divison, so that one identical copy can go to each daughter cell =because the two strands of a DNA molcule have complementary base pairs, the nucleotide each can be used as a pattern or template to produce a complementary strand together then form a new DNA double helix, identical to the orginal. The enzyme DNA polymerase then moves along the exposed DNA strand

Answer: The hormones secretin and cholecystokinin target the pancreas, stomach, and gallbladder.
Explanation:
The duodenum secretes two additional hormones. Cholecystokinin (CCK), like enterogastrone, is secreted in response to the presence of fat in the chyme. CCK stimulates the contractions of the gallbladder, injecting bile into the duodenum so that fat can be emulsified and more efficiently digested. The other duodenal hormone is secretin. Released in response to the acidity of the chyme that arrives in the duodenum, secretin stimulates the pancreas to release bicarbonate, which then neutralizes some of the acidity.
