The ph of four different solutions are recorded below which solution is more acidic a. ph=3 b. ph=7 c. ph=10 d. ph=14

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

you know they are heterozygous for a trait because they have it as jj or jj.
