One type of chicken has three different types of feather: white, speckled (spotted black and white) and black. A speckled chicken is mated with a black chicken. If 8 chicks are born, how many would be speckled?

A)8

B)4

C)6

D)2

I'm going to use the letter W for this

Going by the question, white is the dominant trait.

WW = white

Ww = speckled

ww = black

4 chickens would be speckled because 50% of the punnet square is Ww

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

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
