Question doesn't relate to hypothesis - fix! AP Lab – Cellular Respiration Question: How does temperature affect the rate of cellular respiration in germinating and dry peas? Hypothesis: If both germinating and dry peas are placed in a respirometer and submerged in room temperature water and water with a temperature of 10 °C, then the respirometer with the germinating peas will prove a greater rate of cellular respiration than that of the dry peas in both temperatures of water. Procedure: See lab handout Data: See attached Analysis Questions #1-10 1. Conditions that must remain constant in this experiment include the temperature of the water baths and the volume of peas and beads in the respirometers.
Fern Spore Germination and the Effects of Ammonium Nitrate Name Lab Partner: U-# BSC: 2011L Section: 908 April 10, 2014 Abstract: The effect of 1% ammonium nitrate on Ceratopteris richardii spore germination was tested in this experiment. Past experiments have been done on Botrychium dissectum and they found that when the spores were grown in the presence of ammonium, they had the best growth rates. Also when they had ammonium nitrate present, even more spores germinated compared to when they only used nitrate by itself. They did several tests using nitrate, ammonium, and then a combination of ammonium nitrate. Basing our hypothesis off of this past experiment, I hypothesized that in the presence of ammonium nitrate we should see an increased germination rate of our spores from the Ceratopteris richardii.
b) Circle or highlight the six most common elements found in living things. Do the same thing for the five other elements that are also found in the body in smaller quantities. (1 point) HINT: Think about the symbols for carbon, hydrogen, oxygen, nitrogen, phosphorus, chlorine, magnesium, sulfur, sodium, and potassium c) Explain how humans obtain the energy and matter they need in order to survive. (1 point) HINT: Think about the chemical bonds and what happens to atoms in your body. The food we eat gives us carbohydrates, lipids and other nutrients to carry out the process of life.
are members of the Enterobacteriaceae and are described as non-lactose fermenter, Gram negative, rod shaped motile organism, ranging 0.7 to 1.5 x 2 to 5 μm in size. This genus has 2 species: Salmonella enterica (six subspecies) & Salmonella bongori. The pH, water activity, nutrient and temperature are important for the growth of Salmonella spp. Temperatures of 35-37°C for 18-24 hours on defined media allow its optimum growth. Temperatures 5.3°C for S. Heidelberg and 6.2°C for S. Typhimurium are the lowest temperatures at which growth has been reported.
LB+:There should have been bacterial growth but no blue colonies because there was an anti-biotic acting against it. LB-: Nothing should have happened because there was no bacteria and plasmid given. 3. One of the plates should have no growth and that was the LB- plate. This happened because the plate was given no bacteria or anything to start growth.
Respiration has two main methods anaerobic- takes place in the absence of oxygen and aerobic respiration- takes place in the presence of oxygen. The main stages of respiration are Glycolysis, TCA cycle and Electron Transport Chain. Glycolysis occurs in the cytoplasm of a cell, this process does not require oxygen and begins

The unknown samples are strontium chloride and copper chloride. Some of the errors that might’ve occurred during our experiment could’ve been due to the fact that we didn’t have much time. Therefore, we rushed through the experiment and might’ve not washed the spatula properly before dipping it into a new substance. Due to this, the color of the flames emitted could vary and not be accurate because the different substances could’ve mixed. Lack of equipment could’ve been one of factors that contributed to our errors.
Stevia is all-natural and comes from a plant, unlike artificial sweeteners. Pure stevia leaves almost no accumulation of the substance behind as it's metabolized, and therefore adds no calories to your diet. Researchers concluded that using stevia instead of table sugar on your diet might be an effective strategy to manage food
