In pea plants, the allele for tall is dominant to the allele for short. Based on the information in the square, how many of the offspring will have a recessive phenotype?

25%

Explanation:

Tt crosses with Tt and you'll get 25% TT, 50% Tt, and 25% tt

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
