Answer:
35y
Step-by-step explanation:
13.15 ounces of 72% acid and 71.85 ounces of 25% acid are needed
<u>Step-by-step explanation:</u>
Total mass of acid required= 85 ounces
Let the mass of 72% acid be 'a'
Let the mass of 25% acid be 'b'
a + b = 85
b = 85-a
85(40/100) = a(72/100) + b(25/100)
85(2/5) = a(72/100) +(85- a) (25/100)
34 = (72a/100) + (2125/100) - (25a/100)
34 - (2125/100) = (72a + 25a) /100
(3400-2125)/100 = 97a /100
97a = 1275
a = 13.15 ounces
b = 85 - 13.14
b = 71.85 ounces
13.15 ounces of 72% acid and 71.85 ounces of 25% acid are needed
Just count the units and that should give you 7 units.
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:
Option B
Step-by-step explanation:
The number that had never been married will vary in each sample due to the random selection of adults.
This number will vary in each sample to the random selection process but they might or might not be as close as possible to one another after sampling.
