Answer:
The phenotypic ratio of the offspring will be 100% of purple flowers.
Step-by-step explanation:
Mendel's first law states that if two pure lines are crossed for a given character, the descendants of the first generation will all be equal to each other, phenotypically and genotypically, and phenotypically equal to one of the parents (of dominant genotype).
The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.
We represent the possibilities of hybridization using a Punnett square in the attached picture.
Uppercase letters represent dominant alleles and lowercase letters represent recessive alleles.
Homozygous individuals have the same pair of alleles. (AA, aa)
We can verify that all offspring have a dominant allele, therefore all offspring will have purple flowers.

Answer: First half was 24 minutes
Step-by-step explanation:
Let the time taken to finish the second half be y.
Since the student used 2/3 of the second half time to finish the first half, first half = 2/3 × y = 2y/3
The entire exam is an hour which equals 60 minutes
First half + Second half = 60minutes
Note that first half is denoted as 2y/3 and second half is denoted by y.
2y/3 + y = 60
5y/3 = 60
Cross multiply
5y = 60 × 3
5y = 180
y = 180/5
y = 36
Second half took 36 minutes
Since first half is 2y/3, it will be:
(2×36) / 3
= 72/3
= 24minutes
First half took 24 minutes.
True because the center is (2,1) and radius is 2
