Answer:
The answer is between a or b
but I strongly suggest the option a.
Evolution is the answer
Answer:
The correct answer is- photosynthesis
Explanation:
According to the endosymbiotic theory, an ancestral cell engulfed a cyanobacteria and lived in symbiotic association with that bacteria and over time this bacteria evolved into the chloroplast and the ancestral cell developed into plant cell.
So as cyanobacteria was the first aerobic cell that can evolve oxygen and can do photosynthesis to produce organic food so it could be concluded that the presence of endosymbiotic cyanobacteria provided a cell with the advantage of photosynthesis.
Answer:
C
Explanation:
Ash from the fire helps restore nutrients
Fires clear out the brush along the ground level before they reach the trees, hence clearing the way to prevent larger fires
Eucalyptus and pine only feed after a fire event when the soil is rich
Therefore the odd one out is C
Answer: The correct answer for the blank is-
B) Sugar and oxygen.
Explanation:
Cellular respiration can be described a metabolic process that includes the break down of organic molecule like glucose (a carbohydrate or sugar) to form carbon dioxide and water along with large amount of energy in the form of ATP ( adenosine triphosphates), which is used for driving various cellular processes.
Aerobic cellular respiration involves the presence of oxygen along with glucose.
Thus, sugar and oxygen, being the reactants in cellular respiration is the right answer.
