Maintaining homeostasis involves many processes. One of these includes the excretion of waste. Our kidneys work very hard to
filter blood of waste products and control how much water is kept in the body. The waste products and water make up urine.
A dehydrated individual would have a concentrated urine that's a darker yellow in color than that of a healthy urine. Why is that?
the liver sends extra urea molecules to the kidney in a dehydrated person
the body reabsorbs the water back into the body, leaving the urine
concentrated
dehydrated urine contains additional ions that cause the urine to have a
different color
the capillaries in the kidney compensate for the water loss by excreting
diluted blood in the urine.

Which statements describe the movement of ocean currents around the globe? check all that apply. strong winds force warm water to sink to the ocean floor. the coriolis effect causes warm and cold water to mix. cool dense water sinks to the ocean floor. warm water replaces cool surface water. wind blowing parallel to the shore causes upwelling of cool water.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.

The average atmospheric pressure on earth is approximated as a function of altitude by the relation patm = 101.325 (1 β 0.02256z)5.256, where patm is the atmospheric pressure in kpa, and z is the altitude in km with z = 0 at sea level. determine the approximate atmospheric pressures at atlanta (z = 306 m), denver (z = 1610 m), mexico city (z = 2309 m), and the top of mount everest (z = 8848 m).
