Biology Homework Assistance Needed

I’m a student working through a Biology homework set and I’m stuck on a handful of questions. I’ll share the assignment as a PDF; what I need back is a clear, step-by-step solution for each problem along with short, plain-language explanations so I understand the reasoning, not just the final answers. Deliverables 1. One document (Word, Google Doc, or PDF) with every question solved and explained in your own words. 2. A concise summary sheet I can use for quick revision. 3. A brief follow-up chat or message thread if anything is still unclear once I review your work. Please keep all explanations original—no copy-pasting from online sources—and cite any diagrams or references you include. Mention your background in Biology or prior tutoring experience when you respond so I can be confident the help is accurate and reliable.
