Which of the following vertebrates had the chance to become abundant after the dinosaurs became extinct?

A man who has type B blood has children with a woman who has type A blood. A. If they are both heterozygous for this trait, pred

Ivenika [448]

Answer:

The possible blood types of their children are: type AB (iAiB), type A (iAi), type B (iBi), type O (ii)

Explanation:

Blood type in humans is controlled by a gene with multiple alleles. Alleles iA and iB are dominant over allele i but co-dominant. The following blood types are encoded by the following alleles:

Blood type AB - iAiB

Blood type A - iAiA or iAi

Blood type B - iBiB or iBi

Blood type O - ii

According to this question, a man who has type B blood has children with a woman who has type A blood. They are both heterozygous, meaning that the man's genotype is "iBi" while the woman's genotype is "iAi". Both parents will produce gametes as follows:

iBi = iB and i

iAi = iA and I

Using these gametes in a punnet square (see attached image), the following possible blood types are produced in the offsprings:

- type AB (iAiB)

- type A (iAi)

- type B (iBi)

- type O (ii)

AveGali [126]

Answer:

What is the indicator we are using in this titration?

a deep blue indicator

Explanation:

What is the indicator we are using in this titration?

a deep blue indicator

the purpose of grinding the spirulina is to be able to break the cell into smaller particles that can dissolve well in a solution.

when powder spirulina is mixed with silica the cells are easily break even.

Should the ground silica and spirulina mixture be suspended in deionized water, exhibit water, or buffer? Why?

ground silica and spirulina mixture be suspended in deionized water because its dissolved and mixed well in water than any other solvent.

What is the color of the folded phytobilliprotein with the bound cofactor?

A blue color is observed when phytobilliprotein is folded.

How do you expect it to change as you add acid or base?

when a base solvent is use for the solution of silica and spirulina (e.g of base NaOH) is used, the colour obseved will be pale yellow or green color.

when a acidic solvent is use for the solution of silica and spirulina (e.g of base HCL) is used, the colour obseved will be colorless solution.

When a base and acidic solvent is used, it causes a changed in the charge state of the protein and changes the interaction thereby causing unfolding.

Individuals with a genetic defect in phenylalanine hydroxylase require an additional amino acid in their diet which is not an es

Daniel [21]

Answer:

Tyrosine.

Explanation:

Tyrosine is a non-essential amino acid, it is part of proteins and is considered an aromatic amino acid. Its synthesis occurs from the hydroxylation of phenylalanine as long as it contains an adequate supply of this amino acid.Phenylketonuria is a hereditary disease whose main treatment is dietary restriction of the amino acid phenylalanine. People with phenylketonuria may have low levels of the amino acid tyrosine in their blood.Phenylalanine hydroxylase is an enzyme that converts phenylalanine to tyrosine. Deficiency of the enzyme phenylalanine hydroxylase is a congenital error of metabolism.
