The data which has been collected from the Garlic sprouting experiment proves to be inconclusive; however this is not to say that the data was not informative, or did not have influence on the questions being asked in the lab. The lab question states “Do insecticides and pesticides used on Industrial Garlic negatively impact the rapidity of growth of sprouts; in comparison to Organic Garlic?”. In answering this question, growth must be studied through time period, and quality of length. When looking at the data from Table 1, it can observe that on May 12 Industrial Garlic grew 1 sprout more than Organic did and on May 17 the Industrial Garlic grew 5 more sprouts than Organic did. However by May 20, just 8 days after initial growth (on May 12), the Organic Garlic has grown more by 7 sprouts. From the point forward, it seems as though Organic Garlic continued to out-sprout Industrial Garlic, until you look at May 25, the last data collection day. At this time you realize that Industrial Garlic had 31 sprouts but Organic Garlic only had 29 sprouts. Looking at Graph 1, we can see that both Garlics have an overall growth trend, in which Organic Garlic seems to start off slower, and grow more exponentially toward the end of the data collection period, but between May 20 and May 24 the data looks as thought it would have started to crash, if growth were to be continuously monitored after the 20 day time period. Industrial Organic seems to have a similar trend, yet the growth in Industrial Garlic seems to climb in sprout count less rapidly than the Organic brand did. It can also be observed that although the Industrial band Garlic dips significantly on May 19, it continues to rise once again for the rest of the time period. This indicat...

...ic did. As said in the discussion, the data proves to be inconclusive due to multiple factors like sunlight, data collection, and period of data collection. The relationship between the dependent variable, quantity and pace of sprouting and the independent variable, brand of Garlic; Industrial versus Organic for this reason is inconclusive in terms of answering the original question asked or proving the hypothesis to be correct or incorrect. In the research, the top 3 most used pesticides on Industrial Garlic were noted. If the data had shown Organic Garlic to yield more growth quicker this would have induced that the common chemicals used in Industrial Garlics cause a stunt in growth of the plant. However this was not the case. A lot of evidence from poor data collection and a negligence of time usage provided an indefinite answer to the stated lab question.
Our control theoretically should have had a higher germination rate than the .5% concentration, but it had a 30% lower germination rate, or 3 beans. We noticed the beans without natron were noticeably healthier and had longer and larger sprouts than those with natron. Additionally, experiments conducted by our peers suggested that the control produced a higher germination rate than those exposed to Natron. This led us to believe there were bad beans in the control group that caused the lower germination rate rather than Natron aiding the growth of the beans. We are doubtful that it was error on our end that caused the failure for we were very meticulous. With the outlier aside, we noticed that as we added Natron at higher concentrations led to less beans being sprouted. From .5% to 1% there is a huge drop off as it goes from 80% germination rate to a 0% germination rate. Based on the data .5% is preferred concentration for exposure, however we cannot confirm this for sure. In future experiments we would use 50 beans in a larger petri dish with the interval going up .1 percent from 0% to 1.5% (15 total petri dishes, 750 total beans). This would allow us to more precisely find where the drop off occurs and the larger bean count would give us a more accurate germination rate. Based on the LC50’s of Anubis (.1) and Natron (.675), Anubis is more toxic as the LC50 is lower, and therefore it requires a smaller dose to have a 50% death rate. Based on this data Natron is a preferred solution for a herbicide for agricultural use because of the higher LC50. However, it should be noted that using Natron will negatively affect the growth of
What is a pesticide?A pesticide is a chemical substance used to kill pests, especially insects. A pesticide is also refered to as a biocide. Most pesticides are applied in spray form but occasionaly you will see pesticides that are in powder or pellet form. Pesticides are used on a variety of things, anything from crops like corn, barley, and wheat, to plants like petunias, marigolds, and rhodadendrons, which are usually found in small gardens greenhouses, and even in your backyard.
Going into details of the article, I realized that the necessary information needed to evaluate the experimental procedures were not included. However, when conducting an experiment, the independent and dependent variable are to be studied before giving a final conclusion.
Have you ever thought about how your fruits and vegetables are grown? How about which ingredients are put into bug sprays and insecticides to ward off those pesky insects? Look no further because author Rachel Carson looks deep into the many environmental issues caused by pesticides and herbicides in her New York Times best-selling novel, “Silent Spring.” “Silent Spring” is a collection of studies which were performed in an effort to educate others about the harmful things occurring everyday to their foods and every-day environment in hopes of giving them a wake up call. This novel is thought by many to be a revolutionary novel that forced people to take notice of the harm being caused in their world, many of which people were unaware of. After discovering the results of these chemicals, it really makes one wonder, is the luxury of being insect free really worth all of the consequences?
Culinary garlic is one of the most medically studied herbs today. it has been cultivated since the Neolithic period around 10,000 BC. This bulb has flavored the food of hunters and nomads after the discovery of its intensively robust flavor. The summarians (2600 BC-2100 BC) were actively practicing the healing powers of garlic, and some believe the summarians to have introduced garlic to China, from where it later spread to Japan and Korea. However, some taxonomists believe garlic to be endemic to China. Records have indicated that the medicinal respect for garlic was not fully appreciated in regions of India, China, as well as in southern Europe. The summarians had been using garlic for some time before others caught on to its medicinal success.
Each Biology 108 section planted these pots and the data from every section was to be combined for an overall data sheet. Our group in section 6 had the role of planting 5 of the experimental pots with the assigned number of wheat seeds or mustard seeds or both.

A question commonly associated with the word insecticides is, what are they? Well I have the answer, insecticides are chemicals that are used to eliminate insects. In the agricultural industry, insecticides are classified into different categories,and the most used is carcinogenic. A carcinogenic insecticide is a substance or agent producing or causing cancer. This is just one of the reason that I believe there are more cons then pros when dealing with a insecticide.. When I was a kid , I can remember my parents taking me and my brother an apple orchard and picking apples. I couldn't wait to eat them until I got home, but we couldn't eat an apple because of what insecticides could be on the apple
Pesticides are used daily throughout all types of places. In rural areas, farmers are applying pesticides on their crops to protect them from the devastation that some insects can have. In urban areas families are using pesticides to protect their houses and their children from pests. There are many different sections of pesticides. Fungicides kill fungus, herbicides kill plants, rodenticide kill rodents, larvicides kill larvae, and bactericides kill bacteria. When people use pesticides, they feel as though their houses and children are protected. Many people don’t see the down fall of using such harsh chemicals. Exposure to harsh chemicals can send your body in a downward spiral.
We used wheatgrass were 40 wheatgrass seeds, two empty pots, soil, and water. We first added soil for both pots and 20 wheatgrass seeds in each pot. My partner and I decided that we label pot one experiment which is “sugar and water” and pot two control which is “water” only. The experiment was for almost four weeks we had to make sure both get the same room temperature and water, so we can see the results after this amount of time. Both pots had same room temperature so both can have the same amount of sunlight also, the same amount of water which is a glass of water from the sink once a week. In the experiment pot we added a glass of water with one teaspoon of sugar and the control pot glass of water. Every week we used to see both pots grow almost the same. At the end of the experiment, my partner and I measured the length for both plants and we recorded the average for each plant, so we can know the rate of growth
Today people are using pesticides and hormones in many of the items that we use each day and it’s affecting our society in various ways. Pesticides are used in many different ways including: keeping insects away from plants, controlling weeds, and controlling the spread of diseases to plants. Hormones make animals grow faster and/or produce leaner meat for food. Although some people believe that pesticides and hormones should be used to help crops and livestock, they can be very harmful to others as well as the environment.
These days and even way back when, we do not know what is in our food! I feel it is a human right to know what’s in our food especially when we are the ones paying whole price for these meals or groceries.

The term “organic” is almost everywhere in modern society, whether it’s used to promote a product or it’s debated on whether it really benefits the human diet. Organic food is heavily debated on as it appears more and more in local grocery stores and farmers markets begin to populate, it raises questions such as “Is organic food better than food grown with pesticides and biologically engineered genes?” and “Are there benefits to eating organically over foods grown in any other way?” In terms of what data and results show in research may help lead to answers to most of the heavily debated issues throughout discussions on organic food.
In addition, since bacterial growth is affected by many other factors such as pH of the medium and age of the bacteria, these factors must be kept constant throughout the experiment to ensure the accuracy of the results.
