Answer #1

4. Option D is the right answer. Autotrophs are the organisms which can survive on inorganic nutrients fir example carbon dioxide.

Autotrophs can produce their own food from the substance available in the surrounding in the presence of either light or chemical energy and can obtain food from inorganic sources whereas Heterotrophs are not able to synthesize their own food and address dependent on other organisms for nutrition and they get their reduced carbon from other organisms.

1a. Choose the false statement: Group of answer choices According to their absorption spectra, chlorophylls a and b are not able to absorb those wavelengths of light that coincide with green light. The role of water in photosynthesis is to provide a source of electrons to replace those ejected from reaction center chlorophyll a when it is activated by light energy. When the light reactions are completed (at the end of the Z-scheme), all the electrons excited by the sun...

6. Which of the four stages of respiration does NOT take place in mitochondria A. pyruvate processing B. glycolysis C. Citric acid cycle D. electron transport and oxidative phosphorylation 7. The citric acid cycle is a set of sequential reactions where 2 carbon atoms from Acetyl CoA (that derives from a glucose molecule) are coupled to a 4 carbon molecule. The carbon atoms from Acetyl CoA are released as CO2. Redox reactions and phosphorylation reactions are used to harvest energy...
