Answer:

Explanation:

In gene transfer, researchers introduce a foreign gene directly into cancer cells or into surrounding tissue. The goal is that the newly inserted gene will cause the cancer cells to die or prevent cancer cells and surrounding tissue from funneling blood to tumors, depriving them of nutrients they need for survival.

In a recent experiment, anti-bacterial hand sanitizer was compared to hand soap. Students washed their hands using the sanitizer
kramer

Answer:

B) The conclusion is not valid; there were fewer bacteria cultures on the soap plates

Explanation:

In a recent experiment, anti-bacterial hand sanitizer was compared to hand soap. Students washed their hands using the sanitizer or soap and warm water for two minutes; then they dried their hands with a paper towel. The standard of comparison was rubbing hands vigorously for 2 minutes in warm water, without any soap or sanitizer, and then drying with a paper towel. The sanitizer advertisement claimed to kill bacteria more effectively than any soap. After washing, hands were swabbed and then the swab applied to a culture plate and incubated. Finally, the bacterial cultures were counted and recorded in the data table. Students concluded that the hand sanitizer was most effective in killing bacteria. How would you respond to the students' conclusion?

                 Hand Washing Test Hand Washing Test

Treatment                                 Bacterial cultures (#/plate)

Warm water                                           24

Hand sanitizer                                       28

Soap A                                                    12

Soap B                                                    13

The above table should have been included before the question. From the table we can conclude that

B) The conclusion is not valid; there were fewer bacteria cultures on the soap plates

Which also means that the sanitizer is not as effective as warm water. it is the least effective solution to kill bacterial.
