Answer: The possible genotype for their child is Hh. All the children will be heterozygous for Huntington (Hh).
The possible phenotype for their child is Huntington disease.
Explanation: If H represents the trait for Huntington and h represents normal trait; and if Huntington trait (H) is dominant over normal trait (h), therefore the genotype of the mother who is homozygous for Huntington disease is HH and the genotype of the man who is homozygous normal is hh.
A cross between the man and woman will produce offsprings who are all heterozygous for Huntington disease Hh. Phenotypically, the offsprings will manifest as Huntington disease.

Answer:
An Oc mutation on the bacterial chromosome can affect the expression of structural genes on a F plasmid.
Explanation:
An Oc mutation is a mutation in which operator of an operon is constitutively active i.e. repressor fails to bind the operator which leads to unregulated gene expression.
An Oc mutation do not affect the expression of structural genes on F plasmid because <u>an operator is a cis regulatory element and therefore it can only affect the genes which are located on the same DNA</u>. F plasmid genes are located on the plasmid not on the main chromosome of the prokaryotes while tryptophan or lac operon system is in the main chromosome that is why an Oc mutation will not impact genes on plasmid.
Answer:
notochord, a dorsal hollow nerve cord and pharyngeal slits.
Electron transport chain is found in both cellular respiration and in the light reactions of photosynthesis.
<h3>What is Electron transport chain ?</h3>
- An electron transport chain is a collection of protein complexes and other molecules that couple protons across a membrane with the transfer of electrons
- from electron donors to electron acceptors via redox reactions. a group of proteins in the mitochondria's inner membrane.
- The oxidative phosphorylation process, also known as the electron transport chain.
- Is a collection of four protein complexes that combine redox events to produce an electrochemical gradient that results in the production of ATP.
- Both photosynthesis and cellular respiration take place in mitochondria.

<span>Hemoglobin
is the part of the red blood cell that carries oxygen, and so important for
thriving. In the case of Brian, having 10.4 g/dL hemoglobin is very low. Normal
values for hemoglobin in males range from 13.5 to 17.5 g/dL. The patient has
very serious anema and note he is just 15 months old, and so needs immediate
doctor’s attention. The doctor is likely to order a blood transfusion to
elevate hemoglobin levels and stabilize the patient before ordering tests to
determine cause of anemia.</span>
