Which of these parts of the membrane help large molecules pass through it?
A. Phospholipid bilayers
B. Phosphorus groups
C. Globular proteins
D. Fatty acids

Answers

Answer 1

Answer:

A. Phospholipid bilayer

Explanation:

Cell membrane is a selective permeable structure in all living cells that allows the passage of some molecules and disallows some. This function of the cell membrane is attributed to the PHOSPHOLIPID BILAYER CONTENT of its structure.

The phospholipid bilayer contains both a hydrophobic end (water fearing) and hydrophilic end (water loving). The interaction of the molecules with these regions of the membrane serves as the basis for the movement of molecules across the cell membrane.

Answer 2

Answer:

Globular proteins! The other answer is sadly wrong.

Explanation:

I just took the quiz. Many globular proteins positioned throughout the cell membrane help the large, polar molecules across. These globular proteins in the cell membrane are the membrane proteins.

Also, I accidently put a 1 star on my own answer, but it's correct.

Describe the overall trend in corn yield from 1988 to 2008. How does the trend in corn yield during the time compare to tends for total nutrients and nitrogen?

Answers

The trend in the corn productivity shows an increase from the year 1988 to 2008.

This is because of high yielding varieties of corn, new technology and application of optimum dose of fertilizer and other agronomic activities. The trend in corn yield for the nutrients and nitrogen increases because new high yielding varieties needs more nitrogen as well as other nutrients as compared to local or old varieties so it is concluded that productivity and nutrients uptake increase with the passage of time.

Which of the following correctly describes the function of the cell wall?


The cell wall provides rigid support and protection for the cell.


The cell wall is a network of fibers inside the cell that gives the cell its shape.


The cell wall is a barrier that allows certain substances into and out of the cell.


The cell wall is a series of folded membranes that produces and distributes proteins in the cell.

Answers

the cell wall provides rigid support and protection for the cell

The cell wall is a layer outside the cell membrane and provides rigid support and protection to the cell. So, the correct option is A.

What is a cell wall?

A cell wall is a thick and rigid layer composed mainly of polysaccharides present outside of the cell membrane that protects the cell. A cell wall is a part of a cell but it is not a living component. Unlike the cell membrane, a cell wall is totally permeable in nature.

The cell wall of different kinds is present in plants, fungi and prokaryotes. Animal cells do not have a cell wall.

The cell wall in fungi is made up of a polysaccharide called chitin. This component is also present in the exoskeletons of arthropods.

The cell wall in the case of prokaryotes is made of a polysaccharide called peptidoglycan. Prokaryotes have 2 layers in their cell wall.

Plants contain cell walls made of cellulose. The plant cell wall has 3 layers. These are pectin, cellulose and hemicellulose. It also contains a small number of minerals.

The materials required for the formation of the cell wall are a special kind of polysaccharide called structural polysaccharides. The monomer for these polysaccharides is glucose.

Therefore, the correct option is A.

The atmosphere exerts a force on earth. Why does yhe atmosphere exert pressure on earth?

Answers

Answer:

The atmospheric molecules have energy because they have a quantifiable temperature. It vibrates and circulates, and bumps into other gas molecules. Most of them are elastic, which means that the molecules bounce off more than they stick together. The "bump" is a strength. It becomes pressure when applied over an area, such as your skin or earth's surface.

Explanation:

How much is the pressure of the atmosphere?

Pressures are determined by height (mostly by the volume of water vapor), temperature, and weather. The average air pressure, however, is 14.7 pounds per square inch, 29.92, or 1.01 to 105 paschal in regular conditions at the marine level. At 5 km altitude, atmospheric pressure is just about 50%. (about 3.1 miles).

Why is the Earth's surface under pressure so much higher? It's because the weight of all the air at that location really is measured. There's not much air around you to press down while you are high in the atmosphere. The whole atmosphere is heaped above you on the surface of the Earth. While the gas molecules are extremely light and distant, they are many!

Heterozygous genotype:The presence of two different alleles at a particular gene locus.A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles.Y for yellow and y for green then the heterozygous parent would be - Yy with yellow phenotype

Question 5(Multiple Choice Worth 5 points)(MC)STORIES OF USEFUL INVENTIONS, excerptBy S. E. Forman1911THE MATCHThere never was a time when the world was without fire, but there was a time when men did not know how to kindle fire; and after they learned how to kindle one, it was a long, long time before they learned how to kindle one easily. In these days we can kindle a fire without any trouble, because we can easily get a match; but we must remember that the match is one of the most wonderful things in the world, and that it took men thousands of years to learn how to make one. Let us learn the history of this familiar little object, the match.Fire was first given to man by nature itself. When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set ablaze by a thunderbolt, we may say that nature strikes a match. In the early history of the world, nature had to kindle all the fires, for man by his own effort was unable to produce a spark. The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by natureby a volcano, perhaps, or by a stroke of lightning. These firebrands were carried to the home and used in kindling the fires there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would sometimes be extinguished. A sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble.In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggist had discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the match with which we are so familiar.Which sentence from the text describes a problem with Walker's match that the phosphorus match tried to solve? A. A sudden gust of wind or a sudden shower would put it out.B. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one.C.
