Briefly describe how cholesterol molecules absence would impact the cells overall function. remember only one cell component can be absent at a time no cell membrane senior skip days.

Absence of cholesterol will affect cellular transport the most as cholesterol is an integral part of the cell membrane.

Explanation:

Cholesterol, an animal sterol, is an important component of the cell membrane. In the membrane, it is abundantly found in regions known as the membrane rafts that are involved with cell signaling in various cellular processes such as cell cycle regulation, immune regulation and cellular transport. Cholesterol also gives the cell membrane its characteristic fluidity that is helpful in membrane transport.

Studies involving the manipulation of cholesterol levels in the cellular membrane have shown a degradation of membrane rafts. Membrane rafts,in the absence of cholesterol, fail to integrate effectively, affecting cellular processes such as membrane trafficking, cytoskeleton organization, and cell cycle regulation.

where is the option.let me know

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
