Bio 111-102 Homework #1‚ Lab 1 assignment My group examined the correlation between standing height and leg length in centimeters for ten of our classmates. Our supposition was that there would be a direct relationship and similarity between standing height in centimeters and leg length in centimeters. Therefore‚ our hypothesis was‚ if leg length increases‚ then standing height will also increase. 1) The steps for the scientific method are: • An observation is made • A question

Bio Lab Report Title: Gram-Negative and Gram-Positive contamination in yogurt. Introduction: There is bacteria that is beneficial and harmful in the human. Yogurt was choosed to be the best example that contains this bacteria. What happens to be the difference between these two types of bacteria‚ and how are they harmful? The bacteria is considered “Gram-Negative‚” and the substance is considered contaminated when there is more negative bacteria than positive bacteria. This will prove or disapprove
