Biology teacher jokes

Today my biology teacher asked me what's commonly found in a cell......... And apparently "black people" isn't the right answer.

I was in bio when my teacher asked what would happen if all predators were gone in an ecosystem.

The kid in the back raised his hand and said, "So what IS gonna happen to you?"

My science teacher was talking about natural selection.

At one point, she asked me to name the first person to theorize about it. I said, "Eric Harris." It was on his shirt.

If you don't get the joke, look up "Eric Harris natural selection."

Why did the biology teacher break up with the physics teacher? Because there was no chemistry...

I only got one question wrong on my biology test yesterday.

The question was, "What is most commonly found in a cell?"

Apparently, "Black People" wasn't the right answer.

My biology teacher told us "get out nice and sharp colored pencils." Does she mean as sharp as in the blades I use to cut myself?
