Based on the Darwinian Snails lab, Seeley showed that snails with thicker shells

Based on the Darwinian Snails lab, periwinkle snails living in New England 100 years ago had shells that were

Determine whether each of the following events is characteristic of mitosis, meiosis, or both.

The spicy heat of chili peppers is due to a chemical called capsaicin. A biologist gathered fruits wild chili plants in four isolated valleys (A, B, C, and D) and measured their spicy heat. The measurements (concentration of capsaicin) were as graphed as follows. Complete the statements below which refer to these graphs representing the four populations of chilies: According to the graphs (be sure to carefully look at the graphs, especially the axes values): Valley [a1] has the highest average spicy heat.  Valley [a2] has the most variation in spicy heat. Valley [a3] has the largest number of chilies.

A student decides to play the Darwinian Snails lab against the rules and eat both the thickest and thinnest shelled snails equally, with all assumptions of natural selection on (thickness is variable and heritable). After a few generations, the snails will likely

Which of the following is TRUE regarding the mitotic phase of the cell cycle?

What requirement for natural selection does the graph below show about the Lake Wapato stickleback population?

Evolution can occur at different speeds, depending on circumstances.

Isoniazid is an antibiotic commonly prescribed to treat Mycobacterium tuberculosis infections (tuberculosis). The antibiotic becomes lethal to bacteria only after one of the bacteria’s enzymes transforms isoniazid into a poison. Some M. tuberculosis do not have a functional copy of this enzyme and are therefore immune to the lethal effects of isoniazid. However, these resistant individuals grow and metabolize nutrients more slowly. The observation that resistant individuals grow and metabolize nutrients more slowly than susceptible individuals is an example of what?

Final Exam – NO LATE PASSESThis exam covers all of the material from the course.You may reference your notes and scratch paper during the exam; however you must complete the test in the allotted time. Late passes cannot be used on exams.Make sure you have completed the readings, notes, and homework for Chapter 10 and have reviewed Chapters 7-9 prior to taking the exam. There are no retakes for exams.The Final Exam makes up 20% of the total grade for the semester. On this exam, you may have:·        Blank scrap paper,·        A scientific calculator.·        Your notes/readings.You may NOT use a graphing calculator, a cell phone, any internet resource, any person, or any “outside” resource.You MUST upload or show your work for all problems for full credit. You cannot pass this exam without showing your work, even if all answers are correct. Showing work is MANDATORY.What does it mean to show thinking if you are using a rule? Explain the rule, such as if you are using the Law of Sines, then state what the law says as the reason for it. For example, 50=1 is not efficient to show thinking. You should write out the “zero exponent rule – anything to zero power is 1” to show why you put that as the answer.You have 240 minutes plus up to 50% of the time extra to work on the exam. This allows plenty of time to show your thinking for EVERY STEP of EVERY PROBLEM. All exams, including submitted scratch paper, must be received no later than 11:59 PM Alaska time on December 12, 2025.How to Submit Scratch Work: There is an option at the end of the exam to type in work or upload photos. Be sure they are in NUMERICAL ORDER.You may also email your scratch paper in NUMERICAL ORDER to your professor as a single document or link to a SHARED Google Doc.Your assessment is not considered complete until scratch paper showing your thinking has been received.
