The molar ratio of sodium acetate to acetic acid in a buffer solution with a pH OF 5.76 is 10:1. Assuming the total buffer concentration is 2.2 X 10^-2 mol/L, how many grams of sodium acetate (m.w. 82) and how many grams of acetic acid (m.w. 60) should be used in preparing a litre of the solution?

Trait is encoded by  genes that are expressed in only one sex . In domestic chickens, display a feather pattern in male and female

Genotype                        Male phenotype           Female phenotype

HH                             hen feathering                      hen feathering

Hh                         hen feathering                            hen feathering

hh             cock feathering (plumage pattern )         hen feathering

If cross between Hh and Hh. what is probability of their progeny with cock feathering

In goats, a beard is produced by an autosomal allele that is dominant in males and recessive in females. We’ll use the symbol Bb for the beard allele and B for the beardless allele. Another independently assorting autosomal allele that produces a black coat (W) is dominant over the allele for white coat (w). A cross allowed between BBbWw (male) X BBbWw (female). What is proportional of female progeny will beard with black coat?
