If a seed is planted, it has a 85% chance of growing into a healthy plant.

BigorU [14]

You can manipulate the number to make them easier to handle

3 and 1/3 times 12=36+4=40
6 and 1/4 times 12=72+3=75
so is 40=100% then wha is 75
40 and 75
divide by 2
20 and 37.5
multiply by 5
100 and 187.5
100=100% and 187.5=187.5%
187.5-100=87.5%

87.5% increase

Please I'm in urgent need of help. what must be added to make (1/4)x^2-(2/3)xy a perfect square?.

Ipatiy [6.2K]

Answer:

$\bigg(\frac{2}{3} {y} \bigg)^{2}$

STEP BY STEP EXPLANATION

$\frac{1}{4} {x}^{2} - \bigg( \frac{2}{3} \bigg)xy \\ \\ = \bigg(\frac{1}{2} {x} \bigg)^{2} - 2. \bigg(\frac{1}{2} {x} \bigg)\bigg( \frac{2}{3} y \bigg ) + \bigg(\frac{2}{3} {y} \bigg)^{2} \\ \\ = \bigg(\frac{1}{2} {x} - \frac{2}{3} y\bigg)^{2} \\$

To make $\red{\bold{\frac{1}{4} {x}^{2} - \bigg( \frac{2}{3} \bigg)xy}}$ a perfect square we should add $\purple{\bold{\bigg(\frac{2}{3} {y} \bigg)^{2}}}$

Purple flower color is dominant to white flower color. If pure-breeding purple flowering plants are crossed with pure-breeding w

Kruka [31]

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.
