The second membrane protects e.coli (Gram-negative bacteria) against a harsh environment.

The outer membrane indirectly helps stabilize the inner membrane as peptidoglycan layer in Gram-negative bacteria is relatively thin than gram positive bacteria ( they have multilayer pepdtidoglycan )

Answer:

The outer membrane of Escherichia coli consists of lipopolysaccharide, phospholipid, protein and Enterobacterial common antigen. The outer membrane as a layer has a protective function. Several specific functions can be attributed to individual constituents. hope this helps!

True or false?
Vinil7 [7]

Answer:

Explanation:

1. Over time more and more molecules of DCPIP would be decreased by electrons taken from plastoquinone (Pq). This statement is true in the sense that DCPIP is an artificial electronic acceptor which is decreased by taking electrons from plastoquinone.

2.) Water splitting by Photosystem II would occur at higher levels than if the drug were administered without DCPIP. This statement is true.

3.)Events in Photosystem I would occur just as they would in the absence of drug and DCPIP. This statement is false because the drug obstructs the electron transport from plastoquinone to cytochrome B. So the events are abnormal because no protein transfer is involved in this mechanism.

Mosses and ferns differ in their reproductive strategies from gymnosperms and angiosperms in which of the following ways?
In-s [12.5K]

Answer:

The correct answer will be option-A

Explanation:

The Mosses are the non-vascular plants that were developed from the aquatic plants and the ferns are the vascular plants which developed from the bryophytes.

Their life cycle shows alternation of generation and is largely dependent on the water for reproduction mainly fertilization or fusion of gametes.

The male gametes produced in these plant groups are haploid and are released in water which fuses in water with female gamete which is distinct from the higher plant groups gymnosperms and angiosperms where fertilization is mediated by mostly the wind or insects.

Thus, option-A is the correct answer.

just olya [345]
The answer is nutrients.

Nutrients nourish the body by providing it with energy and/or contributing to the body's metabolic processes. Nutrients come from food in the form of carbs, fats, and protein, all of which need to be digested by the body before it can use these nutrients.
