Question 1 (2 points) A group of medical researchers investigated the effects of a drug called Pressure Drop X on lowering blood pressure in a group of women between the ages of 60 and 80 years old. The researchers did the following experiment and obtained the indicated results: One group of 150 women took a tablet containing Pressure Drop X for 3 weeks - 95 of these women experienced decreased blood pressure by at least 10%. Another group of 150 women were given a tablet with no added Pressure Drop X for 3 weeks - 10 of these women decreased their blood pressure by 10%. What are the controlled variables in this experiment? Amount of Pressure Drop X O Blood pressure The age and gender of the participants The 3 week time period and sample size of 150 The group of women that received the pills with no added Pressure Drop X Save What is the atomic number of an element with 6 protons, 7 neutrons and 6 electrons ? 07 O 13 06 O 12 Which of the following statements about mitosis and meiosis is NOT true? The cells resulting from meiosis are diploid and the cells resulting from mitosis are haploid. Meiosis and meiosis both starts with one cell, meiosis ends with four and mitosis with two. O Mitosis produces new cells for growth and repair, meiosis produces gametes. Mitosis goes through cytokinesis once, meiosis goes through cytokinesis twice. O Cross over happens in meiosis, but not in mitosis. Save Question 6 (2 points) Which organelle contains digestive enzymes that may degrade different kinds of macromolecules?
