Ap Biology Lab Report Sample

7.The air dried filter paper was then placed on the weighing scale and results were recorded

12.Stir then pour 2.5ml of the enzyme mixture into one of the test tubes not allowing any water from the saucepan into the test tube.

4. After I added the drop that caused the water to flow over, I recorded how many drops stayed on the penny, and I then dried the penny with a paper towel.

The materials that were used to carry out the experiments on the water samples were ten testing kits. We ran 10 tests on all

Introduction We conducted an experiment to see if certain areas in the Daniel Stowe Botanical Gardens, attract certain species of insects. Our group came up with a hypothesis that different type of trees in different locations attracts certain types or certain amounts of insects. Daniel Stowe Botanical is a botanical garden located in Belmont, North Carolina. We chose Danial Stowe, because of its very diverse ecosystem. We thought that since the ecosystems are so diverse that the species of insects should be as well.

6. Now get all 6 of the pipe cleaners that are 21 centimeters in length and place 3 on the upper and lower side. Tape it on now. Not on the foil, but taped and attached to the side of it.

Predominant life fuel resource changed during the body development. ATP is mainly sourced from glucose at fetal phase, then gradually shift to fatty acid metabolism after birth. Studies proved that individuals born with a low birth weight (LBW) have an increased risk of cardiovascular disease in adult life, which glucose transport and related metabolism involved. In this paper, author use the lamb as the IUGR model, tried to find out the effect of changes in the intrauterine environment that result in LBW on key regulatory proteins involved in cardiac glucose metabolism, glucose transport and fatty acid metabolism.

Preview Statement: This daunts involves approximately 14 materials and 15 steps. I will first, go over the materials/ingredients and then cover each of the 10 - 15 steps.

5. It was very challenging to have little to no control over how the photos turn out. Meghan and I had some difficulties putting the photo paper into the chemicals properly, creating a blotchy look to the the photo. Also, somewhere along the line, I did something wrong that created a cloudy look on the photo, which I wish I knew what I did because I would love to learn how to control it, to make it into a cool effect, so thats a happy accident in itself. I was surprised at how difficult it actually was to make a print. Everything that has to be done in advance that takes the time and skill that it does.

3. Volume of water, length of time immersed in water of experimental temperature, surface area of beetroot, position within the beetroot that sample was extracted from (possibly), length of washing

2. Place samples in warm, out of the way place. Leave one sample alone as the control.

On the seventh day, take samples on cotton swabs from each of the 11 beakers and streak them on the remaining agar plates. Do not let agar plate be open for longer than needed, as it may contribute to sources of experimental

5. The weight of each size increment was determined by weighing the residue contained on each sieve. This has be done in a cumulative fashion by starting with the smallest, particles in the bottom pan. After this weight has been determined, the next larger particles was added into the same pan and the cumulative weight was determined.

Step 3 – Sample Preparation: This consists of typically 15 samples being created and tested, each with different asphalt binder content. The samples are tested using the Marshall

The samples were collected in sterile containers and kept in ice box until delivery to the laboratory. Once delivered to the laboratory, the samples were processed for isolation.
