Chemistry
1 answer:
Elenna [48]3 years ago
8 0

Answer:

18. E. 0%

19. D. 25%

Explanation:

Question 18:

Let's use "B" to represent the dominant allele of "light blue skin", and

"b" for recessive "light green skin".

Squidward => BB - light blue skin

Squidward's bride => bb - light green skin

When they cross, they will have the following offsprings:

(BB) × (bb) - Parent

(Bb) (Bb) (Bb) (Bb) - Offspring

All the offspring would be light green skin. The dominant allele of light green skin will express itself over the recessive allele.

Therefore, the chances of Squidward and his bride having light green skin is 0%

Question 19:

Squidward's son => Bb - light blue skin

Squidward's son's bride => Bb - light blue skin

(Bb) × (Bb) - parent

(BB) (Bb) (Bb) (bb) - offspring

They will have the following offspring:

BB and Bb - light blue - 75%

bb - light green - 25%

Chance of having offspring with light green skin is 25%

How can iodine ( Z = 53) have a higher atomic number yet a lower atomic mass than telluriurn ( Z = 52)?
Leokris [45]

Answer:

Iodine have higher atomic size than tellurium because of the presence of more number of protons and lower atomic mass than tellurium because of the presence of lower number of neutrons.

Explanation:

Atomic number of an element is the number of the protons present in the element.

Atomic mass is the sum of a protons and the neutrons which are present in the nucleus of the atom.

Iodine has higher atomic number than tellurium because it has more number of protons than the tellurium.

On the other hand, iodine has lower atomic mass than tellurium because it has less number of neutrons in its core.
