Multiple Choices. Direction: WRITE THE WORD OF the correct answer.A. Read the description of Jose's science investigatory below. Then Answer the questionsthat follow. Write the word/s of the correct answer.Jose investigated the fungicidal ability of akapulko leaf extracts to kill the fungus that causes athlete'sfoot. To extract the antifungal chemicals in the akapulko leaves, he used different liquids such as distilledwater, ethyl alcohol, coconut oil, and acetone. His investigations revealed that the fungicidal ability of theakapulko leaves was most effective with the use of coconut oil as extracting liquid. He thereforerecommended the use of the akapulko leaves-coconut oil mixture for those suffering from athletes foot. Healso recommended that more study be done on other disease-causing fungi.Jose further improved on his science investigatory project by quantifying the effectiveness ofakapulko leaves in inhabiting the growth of the fungus that causes athlete's foot. With the help of amicrobiologist, he performed the agar disc diffusion method, a laboratory procedure for determining theeffectiveness of an extract from the akapulko leaves to kill fungus. He did several trials to determine theextract's effectiveness by measuring the diameter of the zone of inhibition of extracts against the fungus.(The zone of inhibition is a clear round zone that can be observed in fungus-containing agar plate) The clearzone on the agar plate showed that the fungus was not resistant to the akapulko extract.Jose took several measurements (in millimeter) of the diameter of the zone of inhibition. Then hecompared the numerical data of the control set up consisting of coconut oil as the only inhibitory material. 1. The science activity that Jose carried out does not yet have a research title. What titlecan you give for the investigation?2. What are the are the research problems in Jose's investigation? List the main researchproblem followed by the specific research problems.3. You can derive many hypotheses from Jose's research work. Give at least 5 hypothesiswill show the presence of independent and independent variable.4. Jose would like to show the extent of the effectiveness control setup of coconut oilalone. In addition to the pictures taken of the halo zone of inhibition on the agar plate,how else should Jose shows it effectiveness? What graphs should he use? Note that Josehas to compare he average diameter of halo zone between the experimental andcontrol setups.a lake in 30.0 mins. What was the average speed of the boat in kilometres per hour.?
