If someone pours salt water on a plant that is supposed to receive fresh water, the effects on the plant are swift and severe, beginning with the draining of existing water out of the plant cell.<span> Then, the cell membrane separates from the cell wall in a process known as plasmolysis. Ultimately, the plant shrivels up and no longer thrives</span>

Answer:
The correct answer is option A. "V(D)J recombination is similar to the replicative transpositional mechanism".
Explanation:
V(D)J recombination and the replicative transpositional mechanism are very different biological processes. V(D)J recombination is an unique mechanism that takes place by somatic recombination and results in the highly diverse repertoire of antibodies. On the other hand, the replicative transpositional mechanism takes place when a transposable element is duplicated during replication.

1. C
2. D
Explanation:
In an experiment, which aims at solving a particular problem or answering a scientific question about nature, the scientific method is employed. The scientific method contains the following steps:
- Making an observation.
- Asking a question.
- Formulating a hypothesis
- Testing the hypothesis via experimentation
- Analyzing the results
- Conclusion
According to question 1, the PURPOSE of an experiment portrays what is about to be done in a question format. For example, a purpose can go this: What will be the effect of pesticides on the growth of cowpea?. Furthermore, the PURPOSE helps make a research and state a hypothesis in the next step.
- In the analysis of result, the qualitative or quantitative approach is used. The QUANTITATIVE method involves the use of numbers or numerical data to express the outcome or result of the experiment. By counting or measuring, a numerical data is collected and given a unit depending on what is being measured
