Answer:
Nowadays energy generation heavily relies on fossil fuels causing environmental challenges. The global biofuels supply has increased by a factor of 8% since 2010, but only comprises 4% of the world’s transport fuels in 2015. The development of next generation of biofuel becomes increasingly important due to the depletion of fossil fuels and in the meantime to overcome challenges for current biofuels production – high cost and low efficiency. The biological production of lipid droplets in oleaginous microorganisms like microalgae, yeast, fungi, and bacteria becomes a promising path to the next generation of biofuels.
The lipid droplet (LD) is a cellular organelle that consists of a neutral lipid, mainly of triacylglycerols (TAGs) and cholesteryl esters, cored with a monolayer-phospholipid membrane and associated proteins. Lipid droplets widely exist in both prokaryotic and eukaryotic cells, could be collected and extracted for biofuel manufacturing. However, this technology is now limited in lab research. Methods to improve the lipid droplet production in oleaginous microorganisms, biomass pretreatment, lipid droplet extraction, industrial scalability are still under development. The experience of liposome manufacturing provides us a solid ground for lipid droplet studies and helps our clients move to a further step of new biofuel development.

Answer:
The cell membrane will fold over a substance or particle until it becomes completely enclosed by the membrane
Explanation:
Endocytosis is when a substance or particle from the outside is captured and engulfed by the cell membrane until it is in the inside.
Stomach contracting to mix foods with enzymes
Answer;
An example of positive feedback loop is;
-When a pregnant woman begins to go into labor, the body sends hormones that increase the intensity of the labor contractions.
Explanation;
-Feedback loops are therefore the process whereby a change to the system results in an alarm which will trigger a certain result. The result will then either increase the change to the system or reduce it to bring the system back to normal.
-Feedback loops are important because they allow living organisms to maintain homeostasis (maintenance of internal environment of the body constant).
-A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction. It moves a system further away from the target of equilibrium, by amplifying the effects of a product or event and occurs when something needs to happen quickly.
A bacterium called Vibrio cholerae causes cholera infection. The deadly effects of the disease are the result of a toxin the bacteria produces in the small intestine. The toxin causes the body to secrete enormous amounts of water, leading to diarrhea and a rapid loss of fluids and salts (electrolytes).
