The term "albedo" is used to describe the amount of radiation a surface reflects, this is also related to how fast a surface increases its temperature. In general terms, the lighter the surface is the most albedo it has as dark/black bodies absorb all radiation. For example, white snow has an albedo of 80% while dark wet soil has radiation of 10%; also, in the case of water, this has a low albedo (around 10%). According to this, the substance that has a high albedo is white sand as this is a light surface and therefore it is expected it reflects most of the radiation it receives, around 50% (or even more) albedo.
The albedo is the amount of energy that is reflected by a surface. It is determined by the refletivity of that surface. Albedo can range from 0 (no reflection) to a value of 1 (100% reflection). Generally, dark surfaces have a low albedo and light surfaces have a high albedo. Liquid water is considered to have a low albedo, like dark rock and rich soil.
Ventilation is the process which the air moves in and out of the lungs. Diffusion is the movement of gases without the use of energy and or effort by the body. Hope this helps!:)
The correct answer is...Once the enzyme binds to the specific substrate molecule, subtle structure changes occur in the active site, which are reverted when the reaction is over.
<em>The Jan. 21</em> total lunar eclipse will be the last one until May 2021, and the last one visible from the United States until 2022; the most recent total lunar eclipse previous to this one appeared in July 2018.
