Answer : The correct answer for the blank is -

B. nitrogen bases.

DNA (deoxyribonucleic acid) is considered as the genetic material of living organisms and it is passed from one generation to the next generation.

It is composed of sequence of small units, called nucleotide that is primarily made up of three parts-

Nitrogenous base (adenine, thymine, cytosine, and guanine) phosphate group, and deoxyribose sugar.

One living organism is different from another because of the sequence of nucleotides (and thus sequence of nitrogen bases) present in their respective DNA strands.

DNA is first transcribed into mRNA (messenger RNA), which is then converted into particular protein (according to the nucleotide sequence).

The protien is responsible for specific traits in thr organsim.

Thus, option B) is the right answer.

The process of lipid digestion begins even before you take your first bite of food. Just the smell of food can begin digestive j

ikadub [295]

Answer:

The given statements have been rearranged in the following order to depict the flow of events that account for lipid digestion in the human body:

Mechanical digestion by chewing breaks food down.
During digestion, gastric lipases break down fat into fatty acids and triglyceride molecules.
Gastric lipase digests some triglycerides.
The pancreas secretes gastric lipase into the small intestine, where the majority of fat digestion occurs.
Lipid digesting enzymes from the pancreas break down the triglycerides into two free fatty acids and a monoglyceride.
Lingual lipase is secreted from the pancreas and breaks down triglycerides.
With the aid of pancreatic lipase, fats are further broken down into free fatty acids and monoglycerides.
Products of fat digestion are packaged into micelles and transported to the enterocytes.

The process is started in the mouth. Action of the teeth physically breaks down the food and increases it surface area that allows for better access to it for the enzymes to carry out mechanical digestion. Gastric lipases are those in the stomach, most of the lipid digestion takes place in the small intestine with the help of enzymes secreted by the pancreas and the small intestine itself. After digestion, the final products are taken up by the lymphatic system.

Hope that answers the question, have a great day!
