To create the healthiest Helianthus annuus plants, the right amount of sunlight, water, and the nutrients are needed. In this case, the low nitrogen was the one that showed the best results in growth in order to grow Helianthus annuus plants. This lab experiment teaches us about how important the proper nutrients are to plant growth in order for them to grow healthy and have the best
The first hypothesis of this lab was proved false. The first hypothesis of the red light making plants grow the fastest was wrong because the blue light filter made it grow an inch to an inch and a half taller than the red. In the experiment with lettuce, the plants under the red light grew to be 11 centimeters, while the plants under the blue light grew to be 12 centimeters. In the second experiment, plants under the blue light grew to become 14.5 centimeters, while the plants under the red light grew to be 13 centimeters. The second hypothesis, which said that the green filter would make plants grow the slowest, was both correct and incorrect.
Since the data will be checked every day around the same time, the data will be constant, which allows validity and reliability to the experiment. Also, there would need to be a large enough sample to have a statistical significance to determine if the age of a seed actually affects the germination period. Lastly, the pots would need to be bigger and less seeds would be put into the pots. This would help the seeds grow at a proper rate because they would not be competing for resources. Conclusion The data displayed that more seeds in the new pots germinated much quicker than the pots in the old pot; therefore, the age of a seed does affect the germination
The green represents control or Jar 1, the orange represents the smaller jar or Jar 2, and purple represents the larger jar or Jar 3. EVIDENCE FOR COUNTERCLAIM: However, it could be the amount of air exposure that affected the population and not jar size. Jars 1 and 2 had the same amount of air exposure, and their populations remained more similar than Jar 3 throughout the experiment. On the other hand, Jar 3 had about 2 more days of air exposure than the first 2 jars, which may be why Jar 3’s population was so high. This is also supported by the fact that in the late stage of the experiment, the jars had been covered for so long, and that could be why the populations decreased so significantly.
• Data may not be reliable due to slight differences in time of day when seedling was measured which was not completely controlled. Recommendations: • Use marker which does not harm the plant to show exact position of leaf width to be measured each time. • Conduct experiment as season begins and finish experiment at end of season thus avoiding seasonal changes as well as increasing time period allowed to conduct experiment. • Set a specific time of day as to when to measure the plants and perhaps at the end of a day in order to allow continued growth during that particular
These problems have happened in the past like specific incidents in 2008 and 2012, but the company has gotten better by removing the products that included these chemicals. However many people prefer to use a fertilizer that is made up of ingredients that the consumer can trust. Miracle Gro can be healthy and safe for plants if you use the organic fertilizer form. The Organic Choice Miracle Gro product is an alternative store bought fertilizer that is better for the plants and the
Pesticide have become very common in ring for crops but they inadvertently kill of or at the very least repel bees. This again stops the bees from doing their job of pollinating and stops them from getting the food they need to survive. The community can help bees survive by employing a few tactics. One tactic alone will not cure the bee population degradation but it can help boost the bee population. One local and more personal tactic would be to have a “bee garden” that consists of flowering plants that bees like which include apples, oranges, lemons, limes, cucumbers, carrots, and cantaloupes.
Another error could have been that the alcohol was poured straight into pea mixture and was mixed in with the pea and water mixture instead of forming a layer on top of the mixture. This affected the results as alcohol is less dense than the water and pea mixture so the DNA should rise through to the alcohol layer, but without the alcohol layer there will be no movement of DNA. To minimise this in the future, it is recommended that you hold the test-tube on an angle and gently pour the alcohol down the side of the test-tube. Another error could be that the stirring time of five minutes for the meat tenderiser wasn’t timed. This could affect the results as if the meat tenderiser isn’t properly mixed in it could mean that it hasn’t being able to break down the nucleus to release the proteins and even if it has done that it could not have broken down the enzymes that break down DNA that escapes the nucleus.
Other organic foods and liquids are usually good for diluting the nitrogen. Some things are not good for countering these things like vitamin C is not very good in this case. Other things you can do are to look into other fertilizers that don’t have a lot of nitrogen or you could try to make your own healthy beneficial fertilizer. You could also just coat your grass with some of the substances that help dilute the nitrogen. Putting some apple cider vinegar in some natural fertilizer or to spray it on the grass could help.
There would not be an argument to why people should find solutions for CCD and protecting honeybees from parasites, but someone could argue on the effects of reducing pesticide use. Pesticides are major part of keeping crops from getting eaten by insects. Farmers uses many pesticides on their crops If the world can limit pesticide use, destroy parasites, and help reduce CCD, it will be a much better resolution so we can keep honeybees. The solution that has been presented is the best solution possible. Using pesticides more will not outweigh the existence of honeybees.
