Answer:
Using no light
Explanation:
A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results of that specific group.
Using no light would be the control group in this experiment because the experiment is testing the effect that light has on the growth of bean plants.
hope this helps!
Answer:
chloroplasts and mitochondria.
Explanation:
Chloroplasts and mitochondria are the organelles capable of ATP production by photophosphorylation and oxidative phosphorylation respectively. Chloroplasts are the site for photosynthesis. The light reactions of photosynthesis include splitting of the water molecule in presence of sunlight and transfer of electrons from PS-II to PS-I via electron carrier. During electron transport, a proton gradient is created which in turn drives ATP synthesis.
Mitochondria are the site for aerobic stages of cellular respiration. Glycolysis and Kreb's cycle, the first and second stages of cellular respiration produce NADH and FADH2 during the redox reactions. These reducing powers are oxidized by giving their electrons to the terminal electron acceptor, the oxygen molecule.
Electrons from the reducing powers are carried to oxygen molecules via a series of electron carrier proteins embedded in the inner mitochondrial membrane. During electron transport, an electrochemical gradient is created which in turn drives the ATP synthesis.
Based on the study of soapberry bugs and based on the conditions in which studies have been done, it can be concluded that the Soapberry bugs with shorter beaks had a selective advantage in Central Florida because they were better able to feed on Goldenrain fruits.
