In the lab with germinated and dry peas along with glass beads, determining the rate of respiration in each different type of seed was the goal. The hypothesis stated that since the germinated peas were still alive, they would contain a higher rate of respiration needed to remain healthy compared to the dried peas and glass beads.…
An avocado seed is used in this experiment. For this type of seed to start the process of germination, the favorable climate is typically very warm. If someone was to plant an avocado seed and see the quickest results, they should place the seed in the sun. Along with waiting a few days between watering the seed, allowing the soil to dry out. For the seed to germinate properly, the bottom half of the seed will be emerged into water. Once the top of the seed becomes dry it will crack and the exterior brown skin will come…
Hypothesis: The germinating beans will discharge more CO2 than the peas that are not germinating. Materials: 1250 mL respiration chamber Vernier CO2 gas sensor Vernier computer interface thermometer 25 non-germinating kidney beans 25, 24 hour germinating kidney beans 25, two hour warm germinating kidney beans 25, two hour cold germinating kidney beans Paper towels Safety Hazards: There are no need for goggles or gloves within this lab, but be aware of the choking hazard that the beans can cause. Procedure: Gather all materials Prepare a 100 mL beaker of beans/peas with warm water (warm germinating beans/peas), then prepare a 2nd 100 mL beaker with cold water instead of warm water (cold germinating beans/peas)…
Gregor Mendel is an Australian monk, who worked in a garden at a monastery. He experimented with pea plants, and soon became known as the father of genetics. The reason he studied pea plants was because they grow quickly, the traits can be easily observed, and the plant is easy to pollinate. Mendel’s method was to control the pollination of the pea plants and create offspring’s of the two plants that were pollinated together. Using self-pollination and cross pollination, Mendel was able to select plants that had specific traits and observe the traits that appeared in their offspring. The F1 generation is the offspring that is a cross between two parents. The F2 generation is the offspring that is a cross between two individuals in the same F1 generation. A dominant factor is the dominating factor, and the one that masks the effect of the recessive factor for the same characteristic. A recessive factor is one whose effect is taken over by the dominant factor for the same characteristic. Basically, a trait that is controlled by a recessive factor would not appear when paired with a trait controlled by a dominant factor.…
The control plates used in transformation are the LB and second LB/Amp plates marked with a “-“. The control for restriction digest was the ladder. The independent variables are the different cultures of the E. coli, and the +LB/Amp and +LB/Amp/ara plates form the experiment group. The dependent variable is whether the cells glow green under the UV light and whether they are resistant to ampicillin or not. The variables in restriction digest are the other 4 samples. The dependent variable is the length that the DNA fragments travel while the independent variable is the size of the DNA fragments.…

Abstract: This experiment will determine if jumping beans are alive. We tested two groups. Group A and B. We put them in two different areas. Three beans were put in a lit area and three were put in a shaded area.…

Based on the results, the bunchberry plant, with a scientific name of Cornus canadensis, was most frequently seen in station four, the ecotone, and second most in station five, the forest which is most likely in the lower forest since it has a similar environment to that of station four, and third most in station three, the bog. It was not as frequently seen in areas of higher elevation such as the old field. It should be noted that all three locations were very moist which is expected since they receive water from the marsh. Due to its more frequent presence in moist environments, it is predicted that the bunchberry is more adapted to such locations. It is also predicted that sandy soil supports its growth since it was mostly seen in stations four and five which have sandy soil. Within and on the soil, lots of wood could be seen on the ground from remains of trees that were around the bunchberries which lead to a possibility that as the wood remains are buried in the soil, the bunchberry plant is able to use it to build roots.…

3. How does gel electrophoresis work?- Gel Electrophoresis works by first using a gel mold which contains small holes, of which DNA samples are placed. Then, an electrical current is added, making the DNA move. The DNA then moves through the holes in the gel, which the small strands move fastest, therefore sorting the DNA based on size.…
Seeds require moisture to germinate. By presoaking a seed, it strips of the protective layer of the seed and speeds up the rate of germination. But the longer someone presoaks a seed, the greater the chance it has to rot. When presoaking seeds, one should avoid planting them in dry ground due to the risk of the moisture being taken out of the seeds instead of sticking with it to germinate, leaving the seed back to its original state. purpose - There are many factors that affect germination, however this lab will determine how moisture, specifically presoaking seeds will affect germination.…
