Which of the following filter set ups makes a more valid experiment and why?

• separate filters for each of the three tanks, because this ensures a higher quality of water for

each tank

• one filtration system for all three tanks, because this makes filtration a controlled variable
• one filtration system for all three tanks, because this reduces the workload for the researcher
• separate filters for each of the three tanks, because this adds another variable to be tested

and analyzed for inclusion in the experiment's results

Answer:

one filtration system for all three tanks, because this makes filtration a controlled variable Question 8: 65) Which of the following is the muscular action that moves a part of the body away from its median plane?

• pronation
• supination

Answer:

abduction

• bronchioles > alveoli > bronchi > larynx > pharynx > lungs
• mouth/nose > bronchi > bronchioles > alveoli > lungs > trachea
• alveoli > bronchioles > lungs > bronchi > trachea > larynx > pharynx > mouth/nose

Answer:

mouth/nose > pharynx > larynx > trachea > bronchi > bronchioles > alveoli Question 10: 20) Which of the following is the location of fertilization in the females?
