Answer:

The fluid mosaic model was proposed by the Singer and Nicolson in 1972 which stated that the plasma membrane is composed primarily of phospholipids with other molecules like cholesterol, glycolipids and proteins.

Due to the presence of these molecules, the plasma membrane appears like a mosaic of molecules in which the proteins are either present in the embedded in the plasma membrane called " integral proteins" or proteins are attached at the surface known as " peripheral proteins".

Thus, the Fluid mosaic model comprises of the proteins also which forms the second major component of the plasma membrane.

The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components —including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character. The mitochondrial inner membrane contains 76% protein and 24% lipid.

I think there is an answer that might be helpful. Well, you may copy and paste if necessary: The story commence in Boston in 1773. Johnny Tremain, a fourteen-year-old silversmith’s trainee worked for Mr. Lapham, an elderly silversmith, and reside in his house with Mrs. Lapham, the silversmith’s daughter-in-law, and Mrs. Lapham’s four daughters. Johnny is diligent, helpful and he is a leader in the household. Dove, a senior trainee, dislikes him for this which at times make him pick up a quarrel with johnny. From the onset of the novel, the devout Mr. Lapham encouraged Johnny to study a Bible verse about the peril of pride.

Later on, John Hancock, a wealthy merchant, went to place an order for a ornamental sugar basin to go along with his current silverware. Johnny is fascinated by the work on the current set and is amazed to know that Mr. Lapham produced it in his youth. Since Mr. Lapham is aging and is not as skilled as before, Johnny needs to help him to produce the sugar basin.

That partucular night, Johnny started walking on the Long Wharf with Cilla and Isannah, the two youngest Lapham daughters.

Johnny carried his shape of the sugar basin to Paul Revere, a master silversmith, for his opinion. Mr. Revere offered him some ideas on how to make the basin more attractive. Johnny is in a rush to have the finishing work done to the handle before it Mr. Hancock is set to collect it on Monday, so with the aid of Mrs. Lapham, he works on it on Sunday (of which he ought not to do since it is the Sabbath). Dove and Dusty Miller, the younger apprentice, are ought to help Johnny. But on the other hand, they are upset by his arrogant behaviour so they give him a fractured crucible to place the melted silver in. Initially, The prank ought to be a daft rational joke to humble Johnny a little, but he spatter melted silver all over himself and seriously burned his hand. Mrs. Lapham Mrs. Lapham employs Gran’ Hopper, a midwife, to take care of Johnny, but she couldn't keep his hand level so it twist in on itself and turn out to be hopeless. Johnny can never be a silversmith now.

Which of the following is a direct benefit of biodiversity?

IRISSAK [1]

improved soil fertility

Explanation:

One direct benefit of biodiversity is improved soil fertility. Biodiversity is the variety of plants and animals living in a particular ecosystem.

A soli is made up of organic matter. Organic matter is the remain of dead and decaying plant and animal materials in the soil.

Organic matter is a very important soil component.

Since plants and animals eat up plants which takes nutrients from the soil, there must be a way to replenish these vital soil materials.

The more biodiverse an ecosystem, the better its chance of adding more nutrients to the soil as they decay.

Why are "red tides" red?Why are these tides seen at some times and not others? What algal division would be most likely to produ

Nesterboy [21]

The red tides are caused because of the algal blooms, which discolor the ocean's water. These tides are red because of the presence of the pigments known as phycobilin. The blue phycocynin and red phycoerythrin contributes to the red color of these tides. The chlorophyll a contained in most of these algae are seen only when the algal blooms although at other times they are still present but deep in the ocean where they cannot be seen.

The green tides will be produced when the green algae, chlorophyta, blooms. These algae obtain energy from the sun for photosynthesis.

Rapid digestion of a cell by its own lysosomes is called

Xelga [282]

When the lysosomes of a cell rapidly digest the cell itself, this process is known as autolysis. This self digestion process helps in the decomposition of the dead cells. The cell is dismantled by its own lysosomes, which digests the remains of the dead cell. It is an essential process in the life cycle of a cell. This self digestion of the cells is extremely important for the new cells to grow.

Hence, the correct answer is 'autolysis'.
