A scientific experiment is conducted to test if calcium can affect gene regulation. Scientists hypothesized that high levels of calcium would interact with the proteins Cs3 and Gfy, which in turn would increase the transcription of genes F4597 and BC392. The experiment procedure is summarized below.
  1. Isolate the genes F4597 and BC392.
  2. Create a vector within yeast cells containing the two genes
  3. Culture yeast cells
  4. Grow yeast cells in different growth mediums- one medium lacking calcium (plate A) and one medium with supplemented calcium (plate B)
Q. What might it suggest if both plates were found to have no gene activity?
  • a)
    An outside variable is suppressing the gene activity and masking the results of calcium. 
  • b)
    There was contamination at one or several steps in the experiment that prevented the yeast from growing.  
  • c)
    None of the statements could be reasons for no gene activity within the plates. 
  • d)
    All of the statements could be reasons for no gene activity within the plates. 
Correct answer is option 'D'. Can you explain this answer?

All of the possible statements are situations that could exist within this experiment. It is very possible contamination took place. If the vectors were not done properly, then the genes might even be in the yeast cells, which would show up as no gene activity. It is also always possible an outside factor not addressed in the experiment is interferring with the results.

Directions:Read the passages and choose the best answer to each question.PassageStudents wanted to test the effects of nutrition on the growth of guinea pigs. Two experiments were conducted using different feeds and vitamin supplements. For both experiments, four groups of 10 guinea pigs each were given a different type of feed over an 8-week period. Each group received the same quantity of food and was provided with fresh water daily. The guinea pigs were measured and weighed weekly. The guinea pigs in each group had an average starting weight of 50 grams (g) and an average starting length of 20 centimeters (cm).Experiment 1Group 1 was fed a high-protein feed (Feed P).Group 2 was fed a grain-based feed with vitamin supplements (Feed Q).Group 3 (control group) was fed a grain-based feed without supplements (Feed R).Group 4 was fed a grain-based feed without supplements plus fruits and vegetables (Feed S).The results and average measurements are recorded in Table 1 below.Experiment 2Group 5 was fed a high-protein feed plus fruits and vegetables (Feed V).Group 6 was fed a grain-based feed with vitamin supplements plus fruits and vegetables (Feed W).Group 7 (control group) was fed a grain-based feed without supplements (Feed X).Group 8 was fed a grain-based feed without supplements plus fruits only (Feed Y).The results and average measurements are recorded in Table 2 below.Q.If the students added vitamin supplements to Feed V for a new group (Group 9), what might the result be after 8 weeks?

Scientists studied a species of termites and looked at their foraging habitats across the United States. The termite’s population in a given tree was measured by the level of decomposition within a tree due to the termites eating the bark. The experiment also kept track of the level of shade tolerance for each species of tree. For the species of trees in this experiment, shade tolerance fell into two main categorizes- shade tolerant (ST) and intermediate shade (IS). Lastly, they recorded the average amount of rainfall in that given month for the species location being observed. The chart below summarizes the data. Scientists hypothesized that the level of decomposition would be highest in tree species with a higher average rainfall. In addition, they hypothesized trees allowing more shade would allow for more termites, and in turn more decomposition.Q.Based on this experiment, the optimal foraging habitats of termites can best be described as __________.
