Biology 10 Vinegar Eel Lab Adam Dorner 1) The most toxic metals were silver‚ lead and iron‚ all killing the eels in under four minutes‚ with silver taking only 1 minute and 40 seconds to kill the eels‚ and only 13 seconds to make the eels stop forward motion. Strontium wasn’t effective as after 5 minutes of exposure to it‚ the eels hadn’t died or stopped forward motion. 2) a) The accepted toxicity varies from metal to metal. The accepted toxic level of lead is 0.0012 parts per million‚ however

Part 2: Effects of Environment on Mitosis. Experimental Hypothesis: If we put onion root tips in IAA solution then the rate of Mitosis will increase. Null Hypothesis: There will be no difference Part 1- Post Lab Question If a cell contains a set of duplicated chromosomes‚ does it contain any more genetic information than the cell before the chromosomes were duplicated? No‚ because if it is duplicated‚ it would have the same number of chromosomes unless there was a

The Origin and Evolution of Life on Earth Why do we start the discussion of biology with a discussion of geology? Here are some reasons why one would do this: * All life on earth is linked to geology; likewise‚ many surface geologic features and processes have been influenced by life on earth. The origin and early evolution of the earth are especially important when looking at the origin and early evolution of life on earth. * Life chemistry had its origin with the elements available to

Exercise 4 Lab Report (3) Individual: Prepared blood slide (a.) Compare red and white blood cells - what cellular features are present in white cells but not in red blood cells and vice versa? Include a digital image of the blood cells present in the permanent dry. Red Blood cells carry hemoglobin inside of them which helps carry oxygen from the lungs to the rest of the body. Hemoglobin is what gives blood cells the red pigmentation. The amount of blood cells present in the blood give it

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

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
