Answer:
True
Explanation:
Water freezes faster than alcohol due to lower freezing point.
Water takes less time to freeze than alcohol but can absorb a large amount of heat with only a small change in its temperature. Alcohol has -114.7 degrees Celsius of freezing temperature whereas water has freezing point of 0 degrees Celsius.
The given statement is true. Water freezes faster than alcohol. Due to its lower freezing point than alcohol, water freezes more quickly.
Why water freezes faster than alcohol?Alcohol takes longer to freeze than water, but water can absorb a lot of heat with just a slight change in temperature. Water has a freezing point of zero degrees Celsius, but alcohol has a freezing point of -114.7 degrees Celsius.
Because water molecules must be forced to move more quickly within the water in order for the temperature to rise, water is more able to absorb heat than many other substances. As a result, water freezes more quickly than alcohol.
Therefore, The given statement is true. Water freezes faster than alcohol. Due to its lower freezing point than alcohol, water freezes more quickly.

D) It is used to break down DNA molecules.
Answer:
used to separate mixtures of DNA, RNA, or proteins according to molecular size
Gel electrophoresis is used for the separation of genetic material present in the cell such as DNA, RNA and even proteins. Thus, the correct option is A.
What is Gel electrophoresis?Gel electrophoresis is a technique which is used to separate the genetic material such as DNA fragments, RNA and proteins on the basis of their size and charge. Gel Electrophoresis involves running an electric current through a gel containing the molecules of interest in it.
The principle of Gel electrophoresis is that the DNA or protein sample to be separated is loaded on to a porous gel placed in an ionic buffer. On the application of electric charge, each of the molecules having different size and charge will move through the gel at different speeds and therefore separates out.
Therefore, the correct option is A.

Biology which statement applies to cholesterol?
A. It is hydrophobic and found on the outside of the phospholipid biyaler
B. It is hydrophilic and found inside the phospholipid bilayer
C. It impacts membrane fluidity.
D. It is transported in association with glucose in the blood.
The true statement about cholesterol is that; " It impacts membrane fluidity."
Cholesterol is one of the steroids in the body and serves as a constituent of many hormones. Cholesterol consists of a hydrophilic and a hydrophobic part hence it is able to interact both with aqueous and nonpolar environments.
Cholesterol impacts membrane fluidity in the sense that it regulates the direction of membrane fluidity. At high temperatures, cholesterol raises the membrane temperature whereas at high temperatures, it intercalates between phospholipids thereby preventing stiffening.

Explanation:
Pls give brainliest
A seashore would experience more weathering than the desert. This is because of the gust of wind on the cliff of the mountain.
What is Weathering?
Weathering can be considered as the breaking down or dissolving of rocks and minerals on the Earth's surface. Once a rock or mineral has been broken down by the process called erosion, it transports the small bits of rocks and minerals away from each other. Water, acids, salt, plants, animals, and change in temperature are all the agents of weathering and erosion.
A cliff along the seashore would experience more weathering, because of the gust of wind from the shore line. This will surely weather out the mountains, including the waves washing out the rocks and minerals.
