Unit Essential Question: How do species change over time and should we intervene? For your project you will argue whether humans should intervene on the behalf of threatened species OR let nature take its course. Use the following table to organize what you learn throughout the tasks, so that you may use it for your culminating project. For each activity, be sure to include answers to ALL the questions provided. Task 2: Evidence of Look back at the fossil record that you created after Task 1. Draw in a pretend common ancestor at the beginning of your fossil record and a pretend modern species also related to this common ancestor. (Feel free to copy & paste what you used for Project Organizer Task 1.) What similar anatomy or embryological development might your species have with this Change Over Time 0 related species?​

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
