Assume the pressure in the lungs is 1.0××1055 PaPaand the air is at a temperature of 300 KK. How many oxygen molecules are in each breath?Louis, Janine, Lamar, and Veronica are conducting a physiology lab experiment where the following question is posed: "Consider a patient visiting a cardiovascular surgeon's office. The surgeon is trying to explain to the patient that he is at high risk for a brain aneurysm (when a blood vessel in the brain "balloons" and eventually bursts). Write down a physical explanation for the cause of a brain aneurysm that the surgeon could use to explain this to the patient." The students write the following responses: Louis: "The blood vessels in the brain are at a higher elevation than the heart and other areas of the body, which means they are subject to greater blood pressure due to the gravitational potential energy stored as well. This increases pressure pushes out on the brain's blood vessels and can cause them to balloon over time." Janine: "When a blood vessel has plaque buildup, the fluid doesn't have as much space to move through, so it must move more quickly. This causes an increase…
- Carbon-14 is radioactive while Carbon-12 is stable. In your body, the ratio of C-14 to C-12 is for every 10,000 C-14 atoms, there are 1 trillion (1,000,000,000,000) C-12 atoms. This is the normal ratio for livings things. In a piece of a sabre-tooth tiger bone, a scientist finds there are only 625 C-14 atoms for every 1 trillion C-12 atoms.How old is the sabre-tooth tiger bone? The half-life for Carbon-14 is 5730 years.This table has results from a flu screening test to determine if a person has influenza virus.

They analyze the fraction of Carbon-14 and Nitrogen-14 atoms in the mammoth. They find that for every 1 Carbon-14 atom, there are 15 Nitrogen-14 atoms. Approximately how old is the mammoth?
- Question 2 1 pts You take a survey that is supposed to measure whether you are an extrovert or not. The score you get on the extrovert survey is a z-score of 2.0. What does that mean about your level of extraversion compared to the average score? O Your score is slightly higher than average. O Your score is is slightly below the mean. O Your score is in the top 10% of scores O Your score is in the top 2% of scores.Can you suggest a possible origin for the helium gas that is part of the Earth's atmosphere?John Snow, an English physician, has observed that disease is becoming more prevalent in a local neighborhood and he wants to know why. He collects information about the local people, including how many family members contracted the disease and where they live. John discovers that the disease is most common in homes located closest to the town’s water pump. John contrives an explanation: that the illness is waterborne and people are contracting the disease from water they retrieve from the town’s water pump. After petitioning the authorities, the handle at the pump is removed. John collects data about disease incidence and finds that occurrence of the disease is greatly reduced. John concludes that the water from the pump was causing the illness. What step(s) of the scientific method is/are missing from Data Table 1? Describe each and propose a way that they might be fulfilled in the scenario?
