Please help I will give brainliest and you get 100 points please actually answer the question don't just say something random I beg. 1. Preheat the conventional oven to about 100 degrees Celsius or 200 degrees Fahrenheit. Make
sure it is at full temperature before you begin.
2. Pour 250 ml of water into one of the microwaveable containers and 250 ml of water into one
of the oven-safe containers. Measure and record the temperature of the water; the temperatures
should be the same in both containers. If they are not, refill them with 250 ml of water that is the
same temperature.
3. Pour 250 ml of sand into one of the microwaveable containers and 250 ml of sand into one of
the oven-safe containers. Measure and record the temperature of the sand. The temperature
should be the same for both containers.
4. Place the container of water and the container of sand in the microwave oven and run the oven
at its highest power setting for two minutes. Remove the containers, and measure the new water
and sand temperatures at the same time. Record your readings.
5. Put the remaining sand and the water containers in the preheated conventional oven together.
Heat the two pans for about ten minutes and then remove both containers from the oven. Use
both thermometers at once to quickly measure and record the temperature of the water and the
sand.
6. Make a chart that lists your results. Answer these questions:
a. What was the temperature change of the water and the temperature change of the sand in each
oven? Which material had the greatest increase in temperature for each type of oven? Explain your results.
b. How would your results change if the water was left in the conventional oven longer? Try it.
c. What kinds of foods cook best in the microwave oven, and which cook best in the
conventional oven? Why?

On a typical day, the average adult will take in about 2500 mL (almost 3 quarts) of aqueous fluids. Although most of the intake comes through the digestive tract, about 230 mL (8 ounces) per day is generated metabolically, in the last steps of aerobic respiration. Additionally, each day about the same volume (2500 mL) of water leaves the body by different routes; most of this lost water is removed as urine. The kidneys also can adjust blood volume though mechanisms that draw water out of the filtrate and urine. The kidneys can regulate water levels in the body; they conserve water if you are dehydrated, and they can make urine more dilute to expel excess water if necessary. Water is lost through the skin through evaporation from the skin surface without overt sweating and from air expelled from the lungs. This type of water loss is called insensible water loss because a person is usually unaware of it.

Regulation of Water Intake

Osmolality is the ratio of solutes in a solution to a volume of solvent in a solution. Plasma osmolality is thus the ratio of solutes to water in blood plasma. A person’s plasma osmolality value reflects his or her state of hydration. A healthy body maintains plasma osmolality within a narrow range, by employing several mechanisms that regulate both water intake and output.

Drinking water is considered voluntary. So how is water intake regulated by the body? Consider someone who is experiencing dehydration, a net loss of water that results in insufficient water in blood and other tissues. The water that leaves the body, as exhaled air, sweat, or urine, is ultimately extracted from blood plasma. As the blood becomes more concentrated, the thirst response—a sequence of physiological processes—is triggered. Osmoreceptors are sensory receptors in the thirst center in the hypothalamus that monitor the concentration of solutes (osmolality) of the blood. If blood osmolality increases above its ideal value, the hypothalamus transmits signals that result in a conscious awareness of thirst. The person should (and normally does) respond by drinking water. The hypothalamus of a dehydrated person also releases antidiuretic hormone (ADH) through the posterior pituitary gland. ADH signals the kidneys to recover water from urine, effectively diluting the blood plasma. To conserve water, the hypothalamus of a dehydrated person also sends signals via the sympathetic nervous system to the salivary glands in the mouth. The signals result in a decrease in watery, serous output (and an increase in stickier, thicker mucus output). These changes in secretions result in a “dry mouth” and the sensation of thirst.
