Biology – Ms. Bartels Due Monday October 21st Limitations on Cell Size Research Question: What is the correlation between surface-to-volume ration and ion exchange and how does this relate to cells? Evaluation of Method and Results: Errors/ Limitations: | Suggestions for improvement: | Impact on Results: | Precision - Human error –cutting cubes freely‚ resulting in very different sized cubes‚ especially for the 1cm x 1cm x 1 cm cubes. All the cubes also had slightly diagonal edges. | One

REVIEW SHEET EXERCISE 2 Skeletal Muscle Physiology NAME: Jasmine Young LAB TIME/DATE: 1. Define each of the following terms: • motor unit - A motor unit consists of a motor neuron and all of the muscle fibers it innervates. • twitch - Skeletal Muscle twitch is the mechanical response to a single action potential. It has three phases known as the latent‚ contraction‚ and relaxation phase. • threshold - the threshold is the minimal stimulus needed to cause a depolarization of the muscle plasma membrane

Comparing Plant and Animal Cells Hypothesis: I predict I will see the following organelles when observing a plant and animal cell under a microscope: the cell membrane‚ cell wall‚ nucleus‚ and the endoplasmic reticulum. Frog Blood: Analysis: 1. The shape of the frog blood cell was in a circle‚ or oval. The edges were a little irregular‚ but it could still be identified as‚ basically‚ a circular shape. 2. The cells were produced by an animal‚ a frog. 3. The cell wall was not present
