Predict how the synaptic configurations of homologous pairs of chromosomes might appear when one member is normal and the other member has sustained a deletion or duplication.

a.
The deletion or duplication of any chromosome region will most likely be detrimental for its synapsis with a normal chromosome.

b.
There will be point-for-point pairing in all sections of the chromosome located between the centromere and the region of deletion or duplication. The rest of the chromosome will show no pairing.

c.
There will be point-for-point pairing in all sections of the chromosome located between the end of the chromosome and the region of deletion or duplication. The rest of the chromosome will show no pairing.

d.
There will be point-for-point pairing in all sections that are capable of pairing. The section that has no homolog will loop out to form a deletion or compensation loop.

Hey me with this one❤☺❤ how do you say that a cell also has a life span and death like an organism? give one example.

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.
