if the galaxies are coming toward us, it's bkieshift but it's always galaxies redshifting from us due to galaxies moving away from us
Answer:
Water in its liquid form has a boiling point temperature close to 100°C. As a result of the network of hydrogen bonding present between water molecules, a high input of energy is required to transform one gram of liquid water into water vapor, an energy requirement called the heat of vaporization.
Cohesion is responsible for the transport of the water column in plants. Adhesion is water attracted to other material.
Water has a greater surface tension than most other liquids because hydrogen bonds among surface water molecules resist stretching or breaking the surface.
Specific Heat is the amount of heat that must be absorbed or lost for one gram of a substance to change its temperature by 1*C.
Density is when hydrogen bonds in water expand as it warms and contracts as it cools. The hydrogen bonds keeps the molecules far enough a part to make ice have fewer molecules.

Answer:
A
Explanation:
Channel and carrier proteins are both considered facilitated diffusion. We also know that materials do not like to go against the concentration gradient so we can eliminate B.
