Use what you have learned about celestial navigation to determine your latitude and longitude using the following data: • The date is June 21(this datum gives you the Sun's declination)

• The altitude of the Sun at solar noon is 35.5 degrees and it is in the southern sky (This allows you to calculate zenith distance and using the Sun's declination the latitude of the vessel)

• Your chronometer set for Greenwich (0 degrees) registers the time of solar noon to be 5:00 pm ( 5 hours later than solar noon at Greenwich - use this to calculate longitude keeping in mind the Earth rotates 15 degrees per hour from West to East)

What is your latitude and longitude?

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.

Were you able to observe the nucleolus in any of the cells if so which ones

The small molecule cyclic amp (camp) takes about 0.2 second to diffuse 10 μm, on average, in a cell. suppose that camp is produced near the plasma membrane on one end of the cell; how long will it take for this camp to diffuse through the cytosol and reach the opposite end of a very large cell, on average? assume that the cell is 200 μm in diameter.
