mina [271]

Answer:

a) Genes b and c are farthest apart.

Explanation:

Transformation occurs when a competent bacteria cell takes up genetic material from the environment. Usually a donor cell donates its gene fragment  which is then incorporated into the chromosome or plasmid of recipient bacterial cell.

Cotransformation occurs when two genes are taken up together by the recipient. The closer the genes lie to each other, more are the chances of them being taken up together. Contransformation frequency will be higher if two genes are close to each other. Here, cotransformation frequencies between three genes are given. Amongst them, the lowest frequency is 0.0064% which is present between gene b and c. Hence, gene b and c are the farthest apart.

Virty [35]

Answer:

to design an experiment aimed at testing the null hypothesis. Finally, it is required to apply a statistical measure in order to reject or accept the null hypothesis

Explanations:

The scientific method consists in the first place in posing a question that can be used to explain an observation from the real world. This question needs to be subsequently explained by a working hypothesis. In this case, the working hypothesis may be "the poor performance of the students is associated with alcohol intake". Then, it is required to design an experiment in order to confirm or reject the null hypothesis. In this case, the null hypothesis would state that there is no relationship between both groups. The further experiment would consist of testing the performance of the students that consume alcohol versus students that don't consume alcohol. Finally, the results obtained from the experiment must be analyzed by using a statistical measure such as, for example, the p-value, which enables to accept/reject the null hypothesis by assessing the significance level of the results.
