Explanation:
it's a set of volcanoes along a plate tectonic. they are created by a divergent boundary which creates seafloor spreading
Answer:
The chance that their <u>child will not be able to roll his tongue will be zero</u>.
The chances to have a child with tongue rolling ability is 100%.
Explanation:
In complete dominance, a dominant gene completely manifests over a recessive gene. If tongue rolling is a dominant trait, this means that the gene that expresses this trait is dominant over the recessive one that does not allow the person to roll the tongue.
If the gene for tongue rolling is called T, then a person that is homozygous dominant for this trait will have the following genotype: TT. If the person is heterozygous for this trait, the genotype will be Tt. And if a person is homozygous recessive for the trait, this person´s genotype will be tt.
When two homozygous dominant individuals mate, their chances to have a child with tongue rolling ability is 100%.
This is:
Parental) TT x TT
Gametes) T T T T
Punnet Square) T T
T TT TT
T TT TT
F1) Genotype: 100% TT, or 4/4 TT
Phenotype: 100% Tongue rolling capable.
The best answer is B.
DNA is sometimes referred to as the blue print of the cell's information because it is the store house in which all genetic information necessary for the cell's survival and reproduction is kept.
Without DNA, there cannot be any continuation of life and no new generation of organisms. All living cells and organisms are essentially made up of protein in different forms. Apart from water, proteins are the most abundant molecules in the cell and body where they serves as the major structural component and are essential for growth and maintenance. Information for all these proteins is found in DNA. Without DNA, there can be no protein hence no life.
The third choice im pretty sure
i hope this helps!!
