Answer:
The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.
Explanation:
Answer:
D) The hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. In the Calvin cycle, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
Explanation:
Photosynthesis is the process by which plants produce carbohydrates (sugars) from carbon dioxide in the atmosphere and water using the energy of sunlight. The process of photosynthesis occurs in two stages: (i) the light-dependent stage and (ii) the light-independent stage.
Light reactions: In this stage, the hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. Also, the energy storage molecule ATP and the reduced electron carrier NADPH are produced.
Light-independent reaction or Calvin cycle: in this stage, carbon atoms from CO₂ are incorporated into ribulose-5-phosphate and used to produce glyceraldehyde-3-phosphate, a three-carbon sugar using the energy of ATP and NADPH from the light reactions. Essentially, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
the results are that it allows its bonds to be easily broken and reformed, special thermal properties, and gives it unique cohesion propertiesthermal properties meaning it can accept heat relatively easily
The kind of organisms able to grow aerobically on slants or at the top of thioglycollate tubes are called facultative anaerobes and o<span>bligate aerobes. Facultative anaerobes are able to function with or without oxygen. In the presence of oxygen, they are able to produce ATP through aerobic respiration. Otherwise, they shift to fermentation or anaerobic respiration. On the other hand, obligate aerobes are organisms that strictly require the presence of oxygen in order to live and grow.</span>
