The effect of a catalyst is to increase the speed of the reaction, this is the speed at which reactants, A and B, are consumed, ant the product, C, is produced.
Given that when C is produced the solution bubbles, the bubbles are an indication of progression of the reaction.
The greater the speed of reaction, the earlier the reaction will end and the earlier the bubbles will stop.
So the student can identify the catalyst because the bubbles will stop first.
Answer: <span>The test tube that stops bubbling first contains the catalyst.</span>
Answer:
Selection may be defined as the process of selecting the more favorable species than the less favored one and can adapt in the environment. The selection increase the chances of survival of the organism.
The genetic variation hidden means the variation is not visible in the population and present in the form of heterozygotes in the population. This genetic variation can be expressed by the recombination of the heterozygotes in the population.

Explanation:
Answer:
Answer b) The result of the experiment identifies that the color of the egg donor branch (parent) prevailed and assigned the color of the offspring.
-The female parental branches that were pure green or pure white had children of pure green or pure white, respectively.
- The female parental branches that were variegated allow to obtain the three types of offspring.
It is evident that the chloroplast shows maternal inheritance.
The branch that is pure green will produce eggs with green chloroplasts that will give rise to a pure green offspring. Thus, a pure white branch will have offspring with ovules with an exclusive content of white chloroplasts and will give rise to a pure white offspring.
If a branch is variegated, it is combined, some with only functional chloroplasts, some with only non-functional chloroplasts, and some with a mixture of chloroplasts. All three types of cells can give rise to ovules, leading to green offspring, white offspring, and variegated offspring.
