Answer:
alleles of a gene separate from each other during meiosis.
Explanation:
Mendel observed that the F1 expressed only one of the alternative variants (in this case, only rounded seeds appeared), while the other variant (wrinkle) disappeared. Mendel named "dominant" the expressed variant. Mendel allowed auto pollination and observed that in the second generation, F2, the other disappeared variant reappeared. Both alternative variants were present in the F2. Mendel named "recessive" the second alternative variant.
Mendel thought that hereditary traits determined by discrete factors were the possible explication for these phenotypes. These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors then separated again when sex cells were produced, giving two types of gametes, each with only one factor.
Mendel concluded that each individual (plant) has a pair of factors (alleles), one for each trait (R and r) and that the pair separates (<u>segregates</u>) during the formation of the gametes. This conclusion is known as the segregation principle (First Mendels´ Low).

Answer and explanation;
-Strong acids and bases are defined as compounds that completely ionize in water or aqueous solution. Weak acids and bases only partially dissociate.
A strong acid will fully dissociate in water to form H+ ions.
HCl + H2O---> H3O+ + Cl-
This reaction is non-reversible. After dissolution, only a very very minute concentration of HCl itself remains in the solution, as most of the diluted HCl has dissolved into ions.
Ka = [H+] [Cl-] / [HCl]
The same applied for bases. The only difference is that the base dissociates to form OH- ions instead.
Strong and weak bases will depend likewise on whether the reaction is reversible.
A strong base will completely dissociate to give more OH- ions.
An example of a strong base;
NaOH + H2O ---> Na+ + OH- + H2O
Kb = [Na+] [OH-] / [NaOH]
