Immunoprecipitation assays are used to determine which of the following? The presence of disease The evolutionary relationship between different organisms The origin of biological samples found at a crime scene. All of the above None of the above Why is hormone human chorionic gonadotropin (HCG) an appropriate material to test for in a pregnancy test? Human chorionic gonadotropin (HCG) is only produced during a pregnancy Human chorionic gonadotropin (HCG) is a cell that is produced by the fetus Hormone human chorionic gonadotropin (HCG) production is lower during a pregnancy All of the above none of the above The doubling period of a bacterial population is 20 minutes. At time \( t=80 \) minutes, the bacterial population was 50000 . What was the initial population at time \( t=0 \) ? Find the stize of the bacterial population after 5 hours. Glucose is produced in the liver by the activation of which receptors? Which of these produces carbon dioxide \( \left(\mathrm{CO}_{2}\right) \) ? alcoholic fermentation both types of fermentation neither type of fermentation lactic acid fermentation All but three spinal nerves have both motor and sensory components. You are conducting a biology experiment and begin with 5000000 cells, but some of those cells are dying each minute. The rate of death of the cells is modeled by the function \( A(t)=A_{0} \cdot e^{-.598 t} \), where \( A_{0} \) is the original number of cells, \( t \) is time in minutes, and \( A \) is the number of cells remaining after \( t \) minutes. How many cells remain after 5,10 , and 25 minutes? Round each answer to the nearest cell.
