Answer:
C. Osmosis
Explanation:
Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.
Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.
Osmosis is controlled to a large extent by concentration gradient.
Diffusion on the otherhand is the movement of molecules of a substance from one position to another.
Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.
Answer:
Sexual selection
Explanation:
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Proin consectetur turpis nunc, in congue diam porta euismod. Pellentesque ornare pretium porttitor. Praesent gravida mollis nunc eget malesuada. Vivamus mollis cursus sapien quis sodales. Etiam vel elementum turpis. Nullam ullamcorper imperdiet felis, at tincidunt quam vehicula vel. Praesent pretium risus vitae odio rutrum facilisis. In hac habitasse platea dictumst.
Answer:
80 * 80
6400
Explanation:
It can be done by simple ways but making it 80^2
80 = 75 + 5
so u can use the formula of (a + b)^2

<span>amylase is an example of an enzyme</span>
In biochemical reactions, it is mostly triggered by enzymes. Enzymes are important components in the process that involves metabolism and digestive functions, further, most of these enzymes are proteins.Proteins are biological macromolecule and mostly composed of enzymes. Proteins play a role in the physical make-up of a cell or acts as a cytoskeleton –maintains cell shape and figure. These proteins plays different roles and works with nucleic acids and other macromolecules in the cells including cell cycle, cell adhesion, immune response and cell indicators.
Adenosine triphosphate (ATP) molecules are produced from the breakdown of sugar and are used as an energy source.
<h3>What is respiration explain?</h3>
The physical processes (such as breath and diffusion) via which a living creature acquires the oxygen it wants to make energy and get rid of waste gases include the act or activity of breathing (as carbon dioxide)
<h3>What is importance of respiration?</h3>
The primary goal of breathing is to deliver oxygen to the cells at the a rate sufficient to meet their metabolic requirements. Through the skin's circulation, oxygen is transported from the lungs to the tissues through this process.
<h3>How many types of respiration are there?</h3>
There are two varieties of breathing: The process of aerobic respiration occurs when there is oxygen present. Absence of oxygen results in anaerobic respiration.
