The best choice is D prokaryotes dont have a nucleus <span />
Answer:Each and every one of us have several roles. Organisms in a community play other roles too. An organism's role within an ecosystem depends on how it earn its nutrients. Organisms collect their nutrients in very different actions, so they have different roles in an ecosystem.
Explanation:
The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.
For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.
Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
Taxonomy is the branch of science that concerns labeling and classifying living things into more manageable groups. This helps scientists better understand certain species and their connections to other species.
The energy released from glucose during this reaction is used and also wasted. Some of the energy is used as work while some amounts are used in other processes or stored for transfer to other organisms. Also, some of the energy is wasted in the form of heat.
Answer:
pancreatic lipase
Explanation:
Enzymes from pancreas involved in triacylglycerol digestion are called pancreatic lipases and they catalyze the partial hydrolysis of triglycerides into a mixture of free fatty acids and acylglycerols. After digestion of lipids, monoglycerides and fatty acids associate with bile salts and phopholipids to form micelles. Micelles are structures that are necessary for the transport the poorly soluble monoglycerides and fatty acids to the surface of the enterocyte. But, micelles cannot be absorbed by epithelial cell, only freely dissolved monoglycerides and fatty acids can. Free fatty acids and monogycerids can just diffuse across the plasma membrane because of their nonpolar nature.
Some absorption (e.g. for cholesterol) may be facilitated by specific transport proteins.
