Experiment Title: Does soil pH affect the color of tomato fruits?
A. Thesis statement: A high soil pH yields red tomatoes.
Set up: 9 pots each filled with soil of varying pH will be used in this experiment. The pots will be assigned into three groups: The control group will contain soil that has a neutral pH, the basic group will contain soil that has a pH greater than 7, and the acidic group will contain soil that has a pH lesser than 7.
The amount of water and sunlight received by the groups should be equal to eliminate other factors that could possibly affect the color variations. By keeping these factors the same, color variation would solely depend on the pH of the soil.
Control Group: It is necessary to keep the soil pH of the neutral group to be exactly 7. By making it neutral, we would be able to know what the natural color is exhibited by the tomato fruits.
The dependent variable in this experiment would be the color exhibited by the tomato fruits. The color exhibited is believed to be dependent on the pH of the soil. By having three samples each with varying pH, it is expected that there will be color variation.
Data Collection:
When the tomato plants bear fruits, determine the color of the fruits produced from each group. Create a table with two columns: the first column would be the group where the fruit belongs and the second column would be the color exhibited. Compare the data gathered from the three groups.
Data analysis:
A scenario which will support your hypothesis would be: the group which contained the basic soil produced red tomatoes. The neutral group produced orange tomato fruits while the acidic group produced yellow tomato fruits. It was found out that the higher the soil pH, the fruit color takes on a redder hue whereas if the pH keeps on going down, the fruit takes on a yellow a hue.
<span>Sheet fractures are accurate fractures defining slabs of rock that range from 0.5 to 10 meters thick. They normally form in sets parallel to the Earth's surface but may form in convex-upward or concave-upward sets. The most popular hypothesis of the formation of sheet fractures is that they are the result of expansion and tangential fracturing consequent on erosion offloading or pressure release.</span>
The fossil record indicates that the earliest hominids most likely originated in "Africa," since this is the location from which humans eventually migrated to other locations.
<span>The correct answer is "Absorption of rainfall by soil."
The hyrdosphere refers to all water on the earth's surface. The geosphere, in this context, refers to the solid parts of the earth (rocks, sand, etc.) Since rain is part of the hydrosphere and soil is part of the geosphere, rain soaking into the soil would be an interaction between the two. The other choices deal with changes in the hyrdrosphere, but there is no interaction with the geosphere.</span>

. Fish need 10 ml of water purifier to survive.
Explanation:
Fish need 10 ml of water purifier to survive because the data of 10 ml and 20 ml purifier is the same so it is recommended to use 10 ml purifier. First the data was same but by recording next week data, it shows slightly increase in the value of tank 2 while in the last week, both has the same value so we can concluded that by using 10 ml purifier is enough for the fish to survive.
