Answer:
Wingless offspring
Explanation:
Complementation is the terminology used for finding difference in the mutation of same or different gene.
Two groups with same complementation have failed to complement each other.
Thus, two wingless flies will have the same genotype i.e “ww”
When two wingless flies are crossed following offspring are produced
ww * ww
ww, ww, ww, ww
All the offspring are wingless too
Answer:
The fourth plant that receives pure water is the control group.
Explanation:
The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, in this case, <em>the different concentrations of salty water that each plant receives</em>. The control group provides a reference point. It must be selected from the same population of the treatment groups. Both groups must be similar in every variable that might influence the results, <u>except for the study treatment.</u>
