Answer:

Biofuels have been around longer than cars have, but cheap gasoline and diesel have long kept them on the fringe. Spikes in oil prices, and now global efforts to stave off the worst effects of climate change, have lent new urgency to the search for clean, renewable fuels.

Our road travel, flights, and shipping account for nearly a quarter of the world's greenhouse gas emissions, and transportation today remains heavily dependent on fossil fuels. The idea behind biofuel is to replace traditional fuels with those made from plant material or other feedstocks that are renewable.

But the concept of using farmland to produce fuel instead of food comes with its own challenges, and solutions that rely on waste or other feedstocks haven't yet been able to compete on price and scale with conventional fuels. Global biofuel output needs to triple by 2030 in order to meet the International Energy Agency's targets for sustainable growth.

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!

Goryan [66]

Answer:

initially, collects in the structure indicated by the letter B

Explanation:

Filtrate is formed as fluid is forced through the walls of the glomerulus and, initially, collects in the structure indicated by the letter B.

Urine formed by a kidney collects in the renal pelvis before being drained from the kidney by the urethra and transported to the urinary bladder.

The process by which glomerulus filtration occurs is called renal ultrafiltration. The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron.
