<span>Amino acids are
weak acids that have at least 2 pka values. They have two titratable protons
that composed of alpha carboxyl (-COOH) and alpha amino (-NH3+), but some amino
acids have a third titratable protons with ionizable groups in the R side chain.
In addition, the structure of amino
acids in peptides and proteins are determined by the charges of the titratable
group and by the R group. </span>
B. widely accepted as true. It can be supported by results that are repeatable. It is widely accepted as true, but not proven as a fact.
Mesophyll cells<span> (both palisade and spongy) are packed with chloroplasts, and this is where photosynthesis actually occurs. </span>Epidermis<span> also lines the lower area of the </span>leaf<span>(as does the </span>cuticle<span>). The </span>leaf<span> also has tiny holes within the </span>epidermis<span> called</span>stomata<span> (H-light green).</span>
There'll be a decrease in health risks and problems, for one.
The correct answer should be <span>biosphere, atmosphere, and geosphere
Soil belongs to geosphere just like the nutrients, the carbon dioxide belongs to the atmosphere, that is the air, and the plant is a living being which is why it belongs to the biosphere.</span>
