- Normal dive (for diving humans) normal breathing dive normal breathing Oz level CO₂ level urgent need to breathe Oz blackout zone high CO₂ triggers breathing 6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in diving humans. • How might the location and slope of the O2 line differ for diving marine mammals such as whales and dolphins? • How might the location and slope of the CO2 line differ for diving marine mammals such as whales and dolphins? • • Draw in predicted lines for O2 and CO2, based on your reasoning above. How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line differ for diving marine mammals? What physiological mechanisms account for each of these differences, resulting in the ability of marine mammals to stay submerged for long periods of time?arrow_forwardHow much ATP will be produced during the following metabolic scenario: Aerobic respiration of a 5mM lipid solution that is made up of one glycerol and an 8-carbon fatty acid and 12-carbon fatty acid.

A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out.
