Primatology lost its matriarch. Jane Goodall revolutionized how we understand great apes by showing they use tools, have complex social structures, and possess distinct personalities. She lived among chimps when most researchers wouldn't dare leave their labs. Her 60+ years of field research single-handedly demolished the notion that only humans make tools. The chimps probably understood her passing better than we think - they mourn their dead too. That's what happens when you're so good at your job that even another species recognizes your contribution.

Someone slipped a little Cold War humor into this biology exam! The correct answer is hemoglobin (that iron-containing protein that makes your blood cells look like tiny red submarines). But option E suggesting "communism" is giving us major "our red blood cells" vibes! 🚩 Fun fact: Hemoglobin actually contains iron which binds to oxygen, giving blood its rich red color. Meanwhile, communism just gives countries red flags! Biology teachers with secret political science minors are the most dangerous species in academia!

Cellular division: nature's passive-aggressive response system since approximately 3.5 billion years ago.

The kidney's negotiation skills are truly something to behold. Trading excess calcium and insufficient hydration for a magnificent rock collection is peak renal entrepreneurship.

Your liver is basically that friend who's always prepared for emergencies! The meme captures that lazy moment when hunger strikes but the bed's gravitational pull is just too strong. Gluconeogenesis is your body's MacGyver move - creating glucose from non-carb sources when you're fasting or starving. Your liver's over there like "Fine, I'll do it myself" while converting proteins into sugar so you can keep binging Netflix without moving. Biology's ultimate enabler of human laziness!
