Explanation:
If a zebra mussel is discovered in a lake in Pennsylvania, then the ecologist would be worried because it is an invasive species. The zebra mussel is native to Ukraine and Russia, but if it has been found in Pennsylvania, than it means that it has been introduced in this area. As an invasive species, the zebra mussel can be very dangerous for the native species in the lake. The invasive species usually are more competitive for food sources than the native species, manage to reproduce quicker, bring in diseases, and the native species tend to not have defense mechanisms for them. This leads to rapid decline or even extinction in the native species, while the invasive spreads out quickly and takes over, resulting in dramatic change in the whole ecosystem.
Answer: The bubbles will form due to the liberation of oxygen gas and white spots will develop on the liver.
Explanation:
The liver is a vital organ, its function is to metabolize the toxins into less harmful metabolites, that are excreted out of the body.
The catalase is one of the enzymes that participate in the metabolic activities of the liver. In the given condition, when hydrogen peroxide and liver were combined. The catalase enzyme breaks down the hydrogen peroxide into water and oxygen. In this reaction, the oxygen gas is liberated, in the form of bubbles and this reaction produces white colored foam which later leaves white spots on the liver.
