Based on the investigation, the inference that can be made about the result is that catalase activity increases with warm temperature.
The liver usually contains an enzyme known as catalase that is capable of breaking down hydrogen peroxide into water and oxygen gas. The bubbles observed in the beaker during the investigation represent the oxygen being evolved from the breakdown of the hydrogen peroxide by the catalase in the liver sample.
At room temperature, a moderate number of oxygen bubbles were observed. The number of bubbles increased with increased temperature as a result of placing the beaker in a warm water bath. At a lower temperature brought by placing the beaker in an ice water bath, no bubbles were observed.
Thus, we can effectively conclude that the activities of the catalase enzyme in the liver increased with a moderately increased temperature.

4. Evaporative cooling can be defined as the process of removal of the latent heat from a surface by the evaporation the evaporation of a liquid from there, which results in the reduction of the temperatures. This technique is used for cooling the homes in the dry and hot areas, such as South Carolina. The dry and hot surrounding there makes it easier for the water to evaporate when it passes through the evaporative coolers, making the surrounding air cooler.
Hence, the given statement is true.
5. When the outside temperature is as high as 83 degree Celsius, while the relative humidity is 66%, , it is likely that the sweating will take place, and the water will be evaporated from the skin, making a person feel cooler.
Hence, the given statement is true.
Answer:
Whales are mammals and do not have gills, so they cannot take the dissolved oxygen that is in the water and turn in into a oxygen that they can breath.
