Giving a ton of you are going to design a clock to represent the different geologic eons throughout earth's history. - research how long each eon lasted. -knowing that each hour of the clock is about 375 million years, determine how many hours each eon takes up on our 12-hour clock. for example, if an eon took 750 million years, that would take up two hours of the clock. -within each eon, identify major events and the types of life that dominated the earth during that time. how you design your clock is up to you. you can use a computer program to design your clock of eons or you can go old school and use poster board and markers.

How many copies of each chromosomes should be present in each of the 4 final haploid versions of gamete?

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.
