is acidic the BTB indicator changes its color into yellow/green. So in this case‚ the water with BTB and carbon dioxide exhaled into the flask creates a carbonic acid. As an aerobic activity increase than the carbon dioxide rate increases as well. 2. By exercising more‚ one’s body requires more energy in their muscles. As the exercise becomes more continual‚ the aerobic respiration is primarily needed. Due to aerobic respiration there is an increase in oxygen intake and more carbon dioxide is released

Introduction: Living‚ microscopic‚ unicellular organisms can be identified as microorganisms. Fungi‚ Protista‚ Bacteria‚ and Archaeans are four kingdoms in the phylogenetic tree of life that consist of microorganisms. Amongst these microorganisms the prokaryotes were the first ones to arrive through evolution. The rest of the life forms as we see them evolved from these simple creatures‚ prokaryotes. The smaller prokaryotes were swallowed by bigger prokaryotes setting the stage for the origin of eukaryotes

Osmosis Lab Report by Evan Gerber Claire Cambron First Lab Report Wednesday 10:30am February 20‚ 2013 Theresa Gburek Abstract The major objective of the experiment was to test the effect of the concentration gradient on the diffusion rate. It was hypothesized that the greater the stronger the concentration gradient‚ the faster the rate of diffusion would be. To test this‚ dialysis tubes were submerged in different concentration fructose solutions. We weighed the tubes at specific
