In general, course assignments in BI234 including exams (lecture, lab, final), homework, laboratory activities, periodic journal article readings, and extra credit opportunities, open at _____ and close at _____ on the assigned days, unless otherwise noted. 

I have read the course policy regarding online exam proctoring requirements found on page #6 of the course syllabus and acknowledge that BI234 requires the use of a remote proctoring service provided by the college called Honorlock, to be used with all course exams throughout the duration of summer term 2025. Amongst other things, Honorlock requires students to test using a laptop or desktop computer (no iPads, tablets, or phones), running an up-to-date Google Chrome browser with an Honorlock Chrome extension. Further, students must have an Honorlock-approved webcam and microphone turned on for the duration of the exam, as exams shall be recorded to ensure a high level of academic integrity. Students should test using a stable high-speed internet connection, and are required to present Honorlock with approved institution or government-issued identification. Additional requirements may be requested by Honorlock.

An autosomal recessive allele in dogs results in white spots. If two solid-colored black dogs are mated and produce a white-spotted puppy, what is the percentage chance that their next puppy would also be a white-spotted puppy?   

Briefly share with me why you’re taking BI234 (or rather, why you’re taking microbiology generally). Further, if you’ve taken another course with me in the past, remind me of what course you took and when (and if you’d like, what you enjoyed about the class). 

I have reviewed the course schedule for BI234 found on pages #3-4 of the course syllabus and there are no conflicts with my schedule that might prohibit my ability to participate in class activities as assigned.
