Answer:
Two different kinds of flasks were used - regular and swan-necked
Explanation:
In his experimental design, Louis Pasteur used tow flasks. One of the flask was regular flask and the other was swan necked. He used these flasks to boil a meat broth. In the swan neck flask, air could enter but microorganisms could not. As a result, there was no grown seen in that flask. In the regular flask, microorganisms could enter and they spoiled the meat. Hence, the two different types of flasks were his experimental design.
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.

The sun heats the land and oceans unevenly, creating areas of upwards and downwards moving air as well as pressure differences. This causes air to flow from one area to another. For hurricanes the sun heats the ocean, causing some water to evaporate. The water vapor powers convection in storms which can then <span>strengthen and organize to form hurricanes. Hope this helps:)
