RNAi is a mechanism involved in gene silencing, the process that turns on and off genes. To do that, it is triggered by double-stranded RNA (dsRNA).
The enzyme "dicer" cuts dsRNA into smaller fragments called (a) small interfering RNA. Once these fragments are cleaved, they bind to argonaut proteins and activate the RNA-induced silencing complex (RISC). This complex targets and degrades (a) specific messenger RNA (mRNA). By degrading the mRNA, this process interrupts the gene expression.

What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 100x and an
Whitepunk [10]

Therefore, a 10x eyepiece used with a 40X objective lens, will produce a magnification of 400X. The naked eye can now view the specimen at a magnification 400 times greater and so microscopic details are revealed. More on objective lenses here. Magnification is the ability to view an object as larger.

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:

  1. Mechanical digestion by chewing breaks food down.
  2. During digestion, gastric lipases break down fat into fatty acids and triglyceride molecules.
  3. Gastric lipase digests some triglycerides.
  4. The pancreas secretes gastric lipase into the small intestine, where the majority of fat digestion occurs.
  5. Lipid ­digesting enzymes from the pancreas break down the triglycerides into two free fatty acids and a monoglyceride.
  6. Lingual lipase is secreted from the pancreas and breaks down triglycerides.
  7. With the aid of pancreatic lipase, fats are further broken down into free fatty acids and monoglycerides.
  8. 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!

Alexeev081 [22]
All you need to look through the human body systems you had in the unit and explain how they make you living, rather than dead. What body systems do you have that make you a living human being.
1. Your Cardiovascular system. It keeps your body and cells supplied with oxygen so they can stay alive.
2. Your nervous system. It allows your body to take outside stimuli and allow your brain to process and react to it.
3. Your Digestive system. It allows you to extract the energy from other living things and use it to power your body.
