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.

Answer:
When the virus infects a cell, the RNA genome enters the cell and programs it to make new virus particles. These virus particles are released from the cell and go on to infect new cells. In humans, poliovirus is ingested, and replicates in cells of the gastrointestinal tract.Poliovirus, the prototypical picornavirus and causative agent of poliomyelitis, is a nonenveloped virus with a single-stranded RNA genome of positive polarity. The virion consists of an icosahedral protein shell, composed of four capsid proteins (VP1, VP2, VP3, and VP4), which encapsidates the RNA genome (1).RNA viruses generally have very high mutation rates compared to DNA viruses, because viral RNA polymerases lack the proofreading ability of DNA polymerases. The genetic diversity of RNA viruses is one reason why it is difficult to make effective vaccines against them.
What are his observations? We can’t answer this without knowing his observations if those are the conclusions. Please provide the rest of the information and I can answer.
