6th: )If a soil sample is 60% sand particles and has 30 million particles of soil, how many of those soil particles are sand?After answering the question and hearing some of your presentations from our lab, we reviewed our work from Friday, took a look at some soil samples, then went on to Section 3, which is due for homework tomorrow.
7th: ) What is the difference between cellular respiration and breathing? Cellular respiration is a chemical process by which cells produce energy from food. Breathing supplies oxygen for cellular respiration and removes the carbon dioxide produced by cellular respiration. After the review, we continued into Chapter 4, on into Section 2. We also learned more about the microscope, and how it works. For tomorrow you need to complete your concept map and pictures of cellular respiration.
