Title: The effect of ethylene production on the unripe banana when are stored together with pear in a bag. Hypothesis: Ethylene is a plant hormone released as a gaseous state into the air by rapidly growing tissues and it affects the surrounding fruits. Iodine solutions bind to the starch of the plant by forming a dark complex. So the darker the fruit, the lesser the content of starch which means the fruit is unripe and vice versa. The lighter color of fruit represents a more ripening status of fruit. Variables. Independent variable: Concentration of ethylene. Dependent variable: Conversion of starch into sugar (ripening of fruit). QUESTION: DESCRIBE 2 CONTROL VARIABLES IN THIS EXPERIMENT: WHAT IS THE METHOD?

Control (describe at least 2): A total of 8 bags will be made, Bags 1-4 will be the control group and 5-8 will be the test group. Put 1 unripe pear in each of the control bags. Seal each bag and one unripe pear and 1 banana in each of the test bags and seal them. Place all the bags together and record the observations from the initial appearance to the…
The herbicide Glyphosate (Roundup) kills plants by inhibiting an enzyme needed for synthesis of phenylalanine. Deprived of phenylalanine, the plant cannot make the proteins it needs, and it gradually weakens and dies. Although a small amount of glyphosate is deadly to a plant, its human toxicity is quite low. Suggest why this powerful herbicide has little effect on humans.
Phytochrome, plays an important role in flowering in many plants. It can also be used to determine when lettuce seeds germinate (shown in the figure below Which scenario(s) above produce large amounts of the active form of phytochrome? A B A & C B & D
Beans increase or decrease the turgidity of Pulvini cells to change the orientation of leaves. In order to raise the leaf blades to a horizontal position (as in the right side of the picture) pulvini cells at the junction between petiole and blade import sugar and potassium ions to increase their Yp from .30 Mpa to 0.67 Mpa. The pulvini cells are at equilibrium both before (leaf held more vertically) and after (leaf held horizontally) moving with an interstitial fluid that is not under pressure and has an unchanging osmotic potential of -3.31 Mpa. What is the osmotic potential of the Pulvini cell when the leaf blade is horizontal?
A team of researchers investigated the effects of phosphorous availability and light intensity on an angiosperm species. Seeds of the angiosperm were divided into four equal groups. Groups 1 and 2 were exposed to 200 µmol, and Groups 3 and 4 were exposed to 500 µmol. Groups 2 and 4 also received a phosphorous (P) solution. After 20 days, all plants were weighed, and the average dry weight of each group was calculated. The results are in the table below. Group Group Group Group 1(200 |2(200 l3 (500|4 (500.
Four species in the Chenopodiaceae were found to have one cell C4 photosynthesis. Givee 3 biochemical properties that could establish that these are C4 plants rather than C3 plants. For each property, describe and explain the test result or data you would expect if the plant is C4 rather than C3.
Addition of meat in the diet which contains heme could increase the absorption of iron from plant sources (non-heme) such as vegetables. How about individuals who practice vegetarian diets? How can these individuals increase the absorption of iron from plant sources? Give reasons why iron from the animal-based sources is better than the plant-based sources in terms of absorption?
Plants often produce waxes on the surface of their leaves to prevent dehydration and protect against insects. What structural feature of waxes makes them suitable for this function?
In a photosynthetic investigation, a student measured the following pH of the stroma and the inner thylakoid compartments of spinach leaf cells at the conclusion of the experiment. Source of Fluid pH (mean) Standard Error of Mean (SEM) Stroma 8.2 0.75 Inner compartment of thylakoid 5.6 0.35 Make a prediction for the pH levels in the plant if it closes its stomata for an extended period of time. Justify your predictions.
Aside from sweet corn, provide some example of plants that has high in sugar content but low in starch based on its chemical properties.
Brewing beer and the determining how to increase ABV involves understanding a little chemistry. Beer is produced with 5 basic ingredients grains, yeast, hops, and water. Grsains contain sugar which ferment into alchol and carbon dioxide. The system of equation that results is: 6x=2z+w 12x+2y=6z 6x+y=z+2w Where x is the number of sugar molecules, y is the number of molecules, z is the number of ethanol molecules and w is the number of dioxide molecules. If 8 molecures of sugar are used the determine the number of ethanol and carbon dioxide moleucles that would be the result _______ ethanol molecules, __________ carbon dioxide molecules
