Question 3: we have discussed the cell biology of the genetic disease cystic fibrosis (cf). the most common
cftr variant associated with cf is a deletion of a phenylalanine at position 508 in the protein sequence. this
is due to the deletion of a codon in the dna sequence that codes for cftr protein.
a. two healthy parents have a healthy son and a daughter with cf. what is the inheritance pattern for cf?

Awater molecule is polar because there is an uneven distribution of these between the oxygen and hydrogen atoms.

You decide that the introduction should also discuss the extremophiles that are referred to as the archaea. these single-cell organisms are considered "extremophiles" due to their ability to survive and reproduce in environmental conditions that would be hostile for most living organisms. archaea species have been isolated from highly acidic sulfur springs, ocean floor thermal vents with temperatures that exceed boiling, and subarctic ice well below freezing. while still considered to be prokaryotic, the archaea have numerous differences that place them apart from the bacteria. choose the characteristics that separate the archaea from other prokaryotic cells. select all that apply. view available hint(s) select all that apply. archaea lack true peptidoglycan in their cell walls. the morphology of the cell is rigid and is geometric in shape, similar to a sphere or cylinder. the cytoplasmic membrane lipids of archaea have branched or ringform hydrocarbon chains. all currently identified and characterized archaea have been linked as the causative agent to an animal or human disease.

When a person is exercising the body needs to deliver increased amounts of oxygen to the muscles which component of blood ensures that the muscles will receive it
