Scientists are studying compounds in a newly discovered rainforest plant. The plant produces an unusual substance that local people say acts as an anesthetic. If another scientist tests the substance using iodine, the scientist testing for carbohydrates.
The existence of carbohydrates in leaves can be sampled by the Iodine test. When chlorophyll is removed from the leaf by boiling it in alcohol and then placing two drops of iodine solution it turns blue in color which indicates the presence of starch.
The iodine test is a test that is utilized to test for the existence of starch. The mixture of starch and iodine produces an extremely blue-black color.

Answer:
1. The Diet Pills
2. The Height Of the plants
3. The plant being watered with tap water
4. 8 Trials were included
Explanation:
1. An independent variable is the variable that you change
2. The dependent variable is what you are measuring, in this example the height of the plant
3. This is what you use to base your conclusion on. In this test they are seeing if diet pills affect the height of the plants. So a plant with no diet pill is the control
4. The results were taken at the end of the week for EIGHT weeks. 8 Trials.
Answer: A
Explanation: All living organisims use energy
Answer:d.are eventually replaced by electrons from photosytem 11
Explanation:there are two photosystems in the photosynthetic process.PSI and PS II. PS I has a reaction center called P700 because it's chlorophyll has a maximum absorption of 700nm wavelength.PSII has a reaction center called P680nm for similar reason.when an excited electron is transferred to P700,it becomes excited.this electron is passed down from from acceptor to another, until it is used to reduce NADP+ to NADPH.this electron is replaced when P680 gets excited by a photo of light and splits water to release electrons , protons and Oxygen
Answer:
· Fermentation does not generate any additional energy, however, NAD+ is regenerated. In the presence of oxygen, pyruvate is oxidized and acetyl CoA is formed, which feeds into the citrate acid cycle and the complete oxidation of glucose.
