A pyramid of energy can never be inverted because energy decreases by tenfold each level. This can't be reversed because energy can't just increase by tenfold. It has to come from somewhere.
Is called autotroph organisms that create organic molecules needed for survival from inorganic sources. this is achieved through photosynthesis (which is light energy) or chemosynthesis (which is chemical energy).
And photosynthesis is when autotrophs capture and convert the light energy from the sun into usable chemical energy (which is their food).
i just answered the same question like 20 min ago XD
Answer:
true
Explanation:
Plants appear green because they contain a pigment called chlorophyll. Chlorophyll absorbs lights; however, the green light is not absorbed but reflected, making the plant appear green.
The antigen-binding sites of an antibody molecule are formed from the molecule's variable regions which are described as so because their amino acid sequences can be different on different antibodies.
The specificity of antibodies is determined by the variable regions found at their endpoints. Antibodies are specialized proteins secreted by B-cells of the immune system. They are also called immunoglobulins. They contain four polypeptide chains that comprise two heavy chains and two light chains to form a Y-shaped molecule.
The variable regions, more specifically the hypervariable regions of an antibody, have a high ratio of different amino acids with the most common amino acids provided in one place. The variable region serves as the antigen-binding site while the constant region found below the variable region is determined to invade the antigen.
Antibodies are preserved in our body to identify the antigen the next time it encounters. They send the signals to the other body parts to reject the antigen and invade it.
