The variable affecting the enzyme action is temperature.
<h3><u>Explanation:</u></h3>
Catalase is the enzyme which acts upon the "substrate hydrogen peroxide", breaking down them into water and oxygen gas. Each and every enzyme is a protein, which has a tertiary structure which is essential for the enzyme action. The tertiary structure of the enzyme provides the site of enzymatic action where the substrate do gets attached for the enzymatic action to take place.
Temperature, or heat, changes the protein structures irreversibly after a certain range. So if the beef liver is boiled, then the enzyme structure gets permanently changed, which is why the catalase cannot breakdown the peroxides, after boiling.
The changes that one can expect to observe as a plant tissue culture develops is the development of new shoots and root.
<h3>What is a Culture?</h3>
This refers to the process in which microorganisms, living matter etc are grown in a specially prepared nutrient medium which are made up of different types of compounds.
In the case of a plant tissue culture, there will be new shoot and root formation due to the presence of nutrients in which the plants are exposed to for its growth and survival.
This is therefore makes changes in the shoot and root be the most appropriate choice.

Um...they become contaminated too, it's just a matter of determining the amount of contamination in the water in ppm & rate of absorption in the organism.
Explanation:
The inbreeding process, are blood crossings between relatives who have a common ancestor. Inbreeding leads to an increase in the frequency of homozygous genotypes and a decrease in the frequency of heterozygotes. We may also note that although changes in genotypic frequencies occur, no changes in allelic frequencies are observed over successive generations of self-fertilization. The main consequence of 2 individuals sharing one or more common ancestors is that they may carry replicas (identical copies) of one or more genes present in these ancestors. And if these individuals mate, they can pass on such replicas to their offspring, generating self-sibling offspring, that is, with two identical copies of the same gene that was present in these common ancestors.
There is about 2 ovaries in a flower.
