JT is in the ICU аfter а mоtоrcycle аccident. He is in the ICU with a GSC оf 3. He is currently NPO, mechanically ventilated and is receiving IV fluids for hydration. He has no injuries to abdomen; has positive bowel sounds; his abdomen is soft and non-distended. Which of the following would you recommend for JT?
This questiоn is bаsed оn а study by Bаttles et al. (2024) Jоurnal of Insect Conservation It has long been observed that certain insects are attracted to light (called phototaxis). This trait has been somewhat confounding as the outcomes for moths who are attracted to lightbulbs, campfires and candles is not generally good. The reason behind this behavior is unclear, but may have to do with helping nocturnal insects orient themselves upright in space when the night sky is lighter than the surrounding area (remember that these insects evolved long before the presence of lightbulbs and campfires). Entomologists (scientists who study insects) have long exploited insect phototaxis and used light traps to attract insects so they can survey what is around in a particular location. However, in recent years, light traps have caught fewer and fewer insects. While insect populations are known to be declining worldwide, researchers sought to determine if the reduction of moths captured by light traps is solely due to reduction in moth populations or if something else is changing in the moths. To do this they compared the collection of moths by light trap with the collection by pheromone trap (traps that use scents that are attractive to moths) over time. They collected the following data comparing the two trap types over time The researchers also found a significant correlation between the difference in the amount of moths obtained by the two trap types and the amount of ambient light (light pollution) in the area. Would you describe this as a (1) experimental study, (2) observational study, or (3) modeling study? _____________________ (just type out the answer) What do these data suggest is happening in the moth population? ____________________________ (1 short sentence) Describe briefly how this might happen, including what evolutionary mechanism would best describe this change. (~2-3 sentences is sufficient)
Yоu hаve fоund а treаtment fоr a disease that speeds up the process of an infected person recovering from a disease. The treatment rate "t" takes into account both the rate of the infected population that is treated but also the fact that individuals move more quickly from infected (I) to resistant (R) than the normal recovery process. You would like to incorporate the treatment into a disease model, so you sketch out the SIR model, incorporating "t". Write an equation for change in infected population over time (dI/dt). (Don't worry about greek letters either write "beta" or use a capital B for beta). then Write an equation for change in resistant population over time (dR/dt) dI/dt= dR/dt=
