Cholesterol is one of the molecules composing the cell membrane. b) makes the cell membrane fluid at room temperature.
<h3>What is the role of cholesterol in the cell membrane?</h3>
The cell membrane is composed of two lipidic bilayers, cholesterol, proteins, and glucans incrusted in between.
Cholesterol is one type of lipid.
These molecules are incrusted in the membrane between the hydrophobic tails of lipids.
Their proportion on both sides of the membrane is almost the same.
Cholesterol is a significant molecule that contributes to the membrane fluidity, separates phospholipids, and interact with membrane proteins regulating in their activity.
The correct option is b). makes the cell membrane fluid at room temperature.

Living in a tropical environment where one learns to orient oneself through a vertical landscape of tall trees and speckled light is part of spatial orientation.
<h3>What is the rain forest zone?</h3>
The tropical rain forest zone is the zone that is known to have a very high amount of rainfall for most of the year. The rain forest zone often has a lot of luxuriant trees that blossom all year round and serve as a breeding ground for many insects such as mosquitoes.
Most of the trees in the tropical rain forest zone are arranged in strata where the tallest trees often form a sort of canopy in the area thereby reducing the light that gets to the pants that are found below and keeping the area cool.
Hence, living in a tropical environment where one learns to orient oneself through a vertical landscape of tall trees and speckled light is part of spatial orientation.

In terms of communication, information is expressed either as the content of a message or through direct or indirect observation. That which is perceived can be construed as a message in its own right, and in that sense, information is always conveyed as the content of a message.
Information can be encoded into various forms for transmission and interpretation (for example, information may be encoded into a sequence of signs, or transmitted via a signal). It can also be encrypted for safe storage and communication.
Answer:
Evidence of metamorphism can be indicated by <u>flat, horizontal</u> layers within the rock.
Explanation:
Metamorphic rocks refer to rocks that are modified with heat or pressure, which change their physical and chemical properties. The main reason behind this modification is the rearrangement of the mineral crystals, which occurs due to their response to the previously-mentioned properties of heat and pressure.
There could be different types of evidence of metamorphism. However, the main evidence can be indicated by the presence of <u>flat, horizontal</u> layers within the rock, also known as foliation, a process that occurs when the pressure squeezes the minerals, leading to a flat, horizontal layer. Then, scientists could analyze the composition of these layers to identify minerals or even fossils within it.
