Biologists use the fluid mosaic model to descfibe membrane structure. Which statements about the fluid mosaic structure of a mem

brane are correct? Select the three correct statements.
a. The framework of a membrane is a bilayer of phospholipids with their hydrophillic heads facing the aqeous environment inside and outside of the cell and their hydrophobic tails clustered in the center.
b. The diverse proteins found in and attached to membranes perform many important functions.
c. Because membranes are fluid, membrane protrins and phospholipids can drift about in the membrane.
d. Membranes include a mosaic, or mix of carbohydrates embedded in a phospholipids bilayer.
e. The kinky tails of some proteins help keep the membrane fluid by preventing the component molecules from packing solidly together.

Answer:A, B, C

Explanation:

A. The arrangement of phospholipids occurs in bilayers with the polar head groups facing both the extracellular and cytoplasmic sides, while the hydrophobic core remains in the center.

The plasma membrane also consists of membrane proteins.

B. Certain integral proteins function as transmembrane proteins that traverse the membrane and create a hydrophilic channel, specifically selective for certain solutes like enzymes, antigens, and hormones.

Peripheral proteins are located on the surface of the bilayer and act as signaling proteins.

C. Membrane lipid bilayers are not rigid or fixed. They exhibit free lateral movement of their components, thus the membrane is fluid in nature. This fluidity facilitates processes like endocytosis and exocytosis.

Describe similarities and differences between jonas's family dwelling and the living area at the annex.
enyata [672]

Jonas finds it fascinating to observe the contrasts and resemblances between his family's home and the living quarters in the annex, particularly regarding the opulent decor and the book collection.

Explanation:

All community members inhabit dwelling, while the Giver resides in the Annex, a compact area attached to the rear of the House of the Old.

In contrast to the dwellings, which are simply furnished without novels or art on the walls, the annex boasts a wealth of books, elegantly designed furniture, and rich textiles.

The interiors of the dwelling serve practical purposes, but they lack vibrancy and visual appeal. The annex includes a buzzer. While dwellings may contain practical books like a dictionary or the Book of Rules, the annex is replete with a variety of other books.

vlada-n [749]

Answer:

The word that is missing is Depletion.

 

Explanation:

Depletion of coral reefs can happen as a result of excessive fishing. The demand for fish increases alongside the growing population rate.

One consequence of unsustainable and unmanaged fishing is that certain fish species may be overfished, potentially leading to extinction.

This creates an ecological disruption, which hastens the decline of the Coral Reef.

Cheers!
