Answer:
A biological membrane can be described as a membrane which encloses a cell. It separates a cell from the outer environment.
The main components of a biological membrane include proteins, lipids and carbohydrates. The carbohydrates either attach to lipids forming glycolipids or they attach to proteins forming glycoproteins.
The structure of a biological membrane constitutes of phosphate heads and tails which are made of fatty acids. The membrane contains a phospholipid bilayer.
Answer:
In gases and liquids, heat is usually transferred by convection, in which the motion of the gas or liquid itself carries heat from one place to another. ... If you boil water in a kettle, the heat is transferred through convection from the fire to the pot.
Depends on how you separate it
Answer:
See explanation
Explanation:
We know that water begins to expand at 4°C. This is generally referred to as the anomalous behavior of water.
The implication of this is that ice has a greater volume than water. Thus ice is less dense than liquid water.
n-butyl alcohol has much less density than water. This accounts for the fact that water upon freezing breaks the bottle while n butyl alcholol leads to a container with concave walls.
Hence the density of ice is much higher than the density of n butyl alcohol.
