But does this have an effect on the plants or are there no differences? In this inquiry it was investigated if there are any effects and how harmful these effects are. Because the plants near the road take a bit too long to grow, there had been decided to work with cress, Lepidium sativum. The inquiry question is: What are the effects of NaCl on cress? Our hypothesis is that the plants won’t encounter disadvantages in low concentrations (up and till 0.20 mol/L), but that they will grow less fast in higher concentrations ( 0.25 mol/L and higher), because NaCl withdraws liquid from plants.
This model could not be altered to include each of these processes because it would require additional items like soil, plants, and a larger jar. 3. How would the “weather” be affected if the water was at a decreased temperature? How would the “weather” be affected if the water temperature were increased? Answer = The weather would be calm in decreased temperatures because you don’t see condensation or evaporation happening when the temperature is cooler.
The results also depict the idea that the shift was beneficial for the plants because they did not reverse the outcome of the pollinator shifts. These pollinator shifts are described as coincidental, meaning that the pollinators’ tongues become longer and as a result, the plants became unable to attach their pollen to these pollinators decreasing the chances of reproductive success, so these plants needed to adapt to avoid an evolutionary dead end. Whittall claims that, "The only decrease in spur length occurred for the smallest
Based on other investigations, vitamins which are made up of organic compounds can help plants grow by providing them with essential nutrients. This time, the researchers tried to use human vitamins. So, in conducting the experiment, first, the researchers labeled the containers of each plant. They labeled the containers: A, B and C. The researchers put all three plants in an area with sufficient sunlight. For three weeks, they watered the plants once a day.
The reason for having a hypothesis-based scientific study is because we do not know the outcome of something. It is similar to many everyday problems in that they are problems because they have not been solved yet, however, a hypothesis-based experiment is different from solving an everyday problem because we do not necessarily have to spend time doing an experiment on everyday outcomes. Some problems are easily solved because we know how they happened and how to fix them. For example, my kids can mix a chemical together and I know to poor it out right away or take it away from them. I do not need to do an experiment on them to know that chemicals are not safe for children.
Although the BWR’s that were built in the 1980’s were advancements on the simple designs of one’s built in the 1940’s, the active systems were the culprit on the flaws within the main designs. The newer ESBWR’s implemented a more passive system inside and outside of the core. Instead of using pumps to implement flow within the core, the ESBWR system uses natural circulation. This will show in the design parameters of each system on the advancements of the BWR design. Although the ESBWR uses none of the active systems that the previous design entails, the power production from the natural circulation, gravity, evaporation, and condensation that the advanced design incorporates is much greater than the previous design.
Compared Rates of Photosynthesis Using Different Light The rates of photosynthesis were compared in different lighting conditions. Two syringes were filled with a bicarbonate detergent solution. Ten leaf diskettes were placed in each syringe filled with the bicarbonate solution and then placed in different lighting conditions. The color of the lights which the syringes were placed were red and white. After the two syringes were placed underneath the lights then results were recorded after certain periods of time.
By having a community garden these families will have access to healthier foods, and in turn can lead to healthier lifestyles and can save money on food. Children will eat healthier and have a more nutrient rich diet. They will eat more fruits and vegetables on a daily basis and this can help lead to a decrease in childhood obesity. Also consuming local produce can reduce exposure to chemicals, fertilizers, and pesticides. Another health benefit of a community garden is the exercise you can get from gardening.
This means that it is expensive and can only be commenced with specialist supervision. The aim with biofeedback is to reduce symptoms associated with stress, such as reducing heart rate or muscle tension. This can be a disadvantage as it does not treat the source of stress. However, it does provide the patient with longer lasting means of dealing with stress symptoms by applying relaxation
The second plant process created from light is photomorphogenesis. This is the effect of light intensity on the plant's individual growth. Some plants need a lot of light to sprout from their seeds, while others initially need little or can even find direct light detrimental to growth. Additionally, light during photomorphogenesis can even affect a plant's circadian rhythms. Lack of sufficient light in this process can often also result in plants that are lacking in normal
