Most women experience their final menstrual cycle around the age of 51. The ceasing of the menstrual cycle is called
menopause, and it signals the end of a woman's reproductive years. It's triggered by a change in hormone levels and
a decline in oocytes. Doctors can perform a test to check a woman's hormone levels to determine if menopause has
occurred. If the woman is in menopause, the test will reveal high FSH levels and low estrogen levels.
How could a decline in the number of oocytes contribute to this change in hormones?

Based on the data in your tables, did the light-colored moths have a higher or lower survival rate after the industrial revolution?

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.

The leopard frog and the pickerel frog are two closely related species. in areas where their ranges overlap, the frogs will remain separate species if they
