Answer: cola-flavored soda: 2.6

cranberry juice: 2.9

pickle juice: 5.5

Explanation:

The substances given are:

cola-flavored soda: 2.6

cranberry juice: 2.9

dish soap: 7.3

pickle juice: 5.5

seawater: 8.0

lye soap: 13.0

Based on a pH scale, an acidic solution is one that has a pH that is below 7, a solution is neutral if the pH is 7 while a basic solution has a pH of above 7.

Therefore, the acidic substance will be:

cola-flavored soda: 2.6

cranberry juice: 2.9

pickle juice: 5.5

Naily [24]

Not the right subject, but anyway,
233 W * 0.001 kW/W 10.8 hours a day * 365 days a year
= 233*0.001*10.8*365 kW-hours/year
= 918.5 kW-h/year

Suppose two BbCc mice are crossed together. Assuming that the two genes assort independently, what are the expected phenotypes,

Katyanochek1 [597]

Answer:

4 types of phenotypes with phenotypic ratio 9:3:3:1 will be obtained.

Explanation:

The Punnett square diagram for the cross between mice with genotype BbCc & BbCc is attached.

It is clear from the diagram attached that the phenotypic ratio will be 9:3:3:1

The following 9 genotypes will show dominant trait for both the characters i.e. characters represented by B & C genes.

BBCC, BBCc, BbCC, BbCc, BBCc, BbCc, BbCC, BbCc, BbCc

The following 3 genotypes will show dominant trait for one character represented by gene B and recessive trait for other character represented by gene C.

BBcc, Bbcc, Bbcc

The following 3 genotypes will show recessive trait for one character represented by gene B and dominant trait for other character represented by gene C.

bbCC, bbCc, bbCc

The following genotype is the only genotype which will show recessive trait for both the characters represented by gene B & C.

bbcc

Find out the difference of a desert plant cell and the cells of normal plants

FromTheMoon [43]

Plant cells are a form of eukaryotic cells with true nucleus and organelles. Various types of plant cells are -xylem cells, phloem cells ,parenchyma cells, collenchyma cells and sclerenchyma cells. These cells distinguish plants from animal kingdoms.

In desert plants like cactus, they have an exquisite set of adaptations for optimal water management. They have thickened stem tissues with thin-walled parenchyma cells so a lot of water can be stored in stems.
