Zebra mussels (Dreissena polymorpha) are originally native to Russia. In the mid-1980's, zebra mussels were introduced into the
Great Lake region of the United States where they rapidly reproduced females can produce up to one million eggs per year. In
one zebra mussel population, most of the individuals have dark zebra-striped
shells (genotype aa) occur in 1 of every 10,000 individuals. The solid light-colored shells indicate mussels that are not hardy in
cold water temperatures (<15°C.
In a population of 10,000 mussels, how many individuals would be heterozygous and contain the recessive gene that might
potentially help rid the Great Lakes of this invasive species?

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.
