Answer:
Eggshells are made of calcium carbonate. If you soak an egg in vinegar the eggshell will absorb the acid and break down, or dissolve. The calcium carbonate will become carbon dioxide gas, which will go into the air.
Explanation:
It will bounce.
I believe that it is testable because you can do it at home.
Independent variable is vinegar.
<span>My pea plant has an unknown genotype for flowers, whether it has two dominant traits for white flowers (WW) or one dominant and one recessive (Ww) leading to white flowers; therefore I am doing a testcross in order to determine the genotype of my pea plant. The best plant to do this with is one that has a phenotype of purple flowers (ww) - that is, it is homozygous for the recessive trait.
If I use a homozygous recessive plant, I know exactly what its genotype is. I don't have to worry about whether it's got one or two dominant alleles; I know that at least half of my alleles are going to be the recessive w.
This makes identifying the offspring's genotype very simple. If I find that the offspring have at least some purple flowers among them, I know that my original plant had to be Ww; that is it had to have one dominant and one recessive allele for the flower color gene. If, however, all of the offspring are white flowers, I know that my original pea plant had both dominant alleles (WW).</span>
Answer: The probability is 100%.
Explanation: The chromosome X is related to gender. A man carries two different chromosomes (XY) and a woman carries two similar chromosomes (XX). The offspring of a couple will inherited:
- If it is a boy, he inherites the chromosome Y from his father and X from his mother;
- If it a girl, she inherites X from her father and X from her mother;
In the question, the woman is color-blind, which means she carries the recessive alleles: 
The man, on the other hand, is normal, so his X-linked genotype will be: 
.
Now, since they have a daughter, she inherited her double X from each of her parents, which means she inherited one 
from her mother and one 
from her father.
So, the daughter's genotype can only be heterozygotic in other words, the probability is 100%.
This will be of good assistance
