Using a computer that is running Microsoft Windows or Macintosh OS 10.1 or higher, go to http://chemcollective.org/activities/vlab/67 and use the “Making Stock Solutions from Solids” application to make the following solution: 250 mL of a 1.5 M solution of Sodium Hydroxide (NaOH) To complete this assignment, follow these steps: Calculate the mass of the solid needed to make the solution. Practice preparing the solution using the simulation in “Making Stock Solutions from Solids.” Use the solution viewer to verify the target concentration. After verifying, reset the application by removing all material. Use the Screencast-O-Matic tool in Studio () in the menu below to record your screen while creating the solution. Explain the preparation process during the recording.

The researchers ran an experiment with the following methods and data to test the hypothesis that male redback spiders willing allow themselves to be eaten by their female mate in order to provide more nutrition to the female that she can pass along to eggs. Method: A male and an unmated female were put into an empty 4×4 plastic container for 30 minutes. Researchers recorded whether the male and female mated and whether the male was eaten. Females were then maintained in standard conditions until laying their eggs. Egg sacs were then weighed and the number of eggs per sac was counted.   Male was eaten Male was NOT eaten     N Median N Median P value Egg sac mass (mg) 9 198 13 179 0.082 Number of eggs per sac 9 256 13 249 0.526 Use this information to answer the next question about science variables.

A patient that is 34 weeks gestation reports heavy bright red vaginal bleeding. She denies any trauma but has been sexually active recently.  The patient is afebrile and denies abdominal pain. Vital signs are R 24, P 118, BP 80/50. The paramedic should have a high index of suspicion for what complication and what is the treatment?
