Answer:
They can infer that it used to be very cold because woolly mammoths and saber tooth tigers used to live in these climates. They might have went extinct because since they are bigger, they didn't have a very big population to begin with, unlike the smaller animals that survived and have now adapted
The target heart rate zone for moderate-intensity aerobic exercise is based on the maximum heart rate which varies with age (decrease with aging). Estimating maximum heart rate can be done by subtracting the age number from 220. So, in this case: 220-32=188
Curtis’ estimated maximum heart rate is 188 beats per minute.
Cellular differentiation is the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types. So I believe the answer you are looking for would be the third one :)
Hope this helps! Please let me know if I'm wrong :)
Removing vegetation and soil, grading the land surface, and constructing drainage networks increase runoff to steams from rainfall and snowmelt. As a result, the peak discharge, volume, and frequency of floods increase in nearby streams. Changes to steam channels during urban development can limit their capacity to convey floodwaters. Roads and buildings constructed in flood-prone areas are exposed to increased flood hazards, in clouding inundation and erosion, as new development continues.
