In this lab, your hands represent an enzyme (), toothpicks represent the substrate , and the broken pieces are the products . The goal is to see how fast you can "catalyze" the reaction of breaking toothpicks. Core Data Trends

"Science isn't about memorizing the answer key, Leo," Henderson whispered, glancing at the doorway. "It's about explaining why the data is broken. Good job."

Below is a comprehensive guide to the answers, data trends, and conclusions for each of these labs. 1. Toothpickase Enzyme Lab Answers

It was the day of the "Predator-Prey Simulation," universally known among the sophomore class as the Toothpick Lab.

Demonstrate surface tension and detergents.

Co-dominant (RY creates an orange fish) but recessive to green. Common Lab Answers Toothpick Fish - Genome Sciences Education Outreach

Model allele segregation (using broken vs. whole toothpicks as dominant/recessive).

| Question | Expected Answer | |----------|----------------| | What is the independent variable? | Time (or number of toothpicks remaining) | | Dependent variable? | Number of toothpicks broken | | Controlled variables? | Type of toothpick, breaking method, time intervals | | Why use toothpicks? | Easy to break, cheap, visual model of particles | | What does breaking represent? | Chemical reaction or enzyme action | | Rate at start? | Fastest (high substrate) | | Rate at end? | Slowest (low substrate) | | Graph shape? | Curved, leveling off |

"Okay, let's review," Henderson said, walking to the whiteboard. "Based on our data, which color was the 'fittest'?"
