Coal, oil and natural gas carbon dioxide (CO2)
Answer:
The correct answer will be option-B.
Explanation:
Cellular respiration is a slow process which produces energy from the oxidation of food components which could be glucose, fatty acids and proteins.
The process proceeds in four steps: glycolysis, link reaction, Krebs cycle and electron transport chain.
The energy molecules are produced when a high energy electron gets reduced and the released energy is stored in the form of energy molecules which could be ATP or energy equivalents like NADH and FADH₂.
These reducing equivalents donate its electrons during electron transport chain where the electrons flow to the last electron acceptor called oxygen.
Thus, Option-B is the correct answer.
Cell membrane (that wraps around the cell doing so)
Answer:
1: sun-->grass-->rabbit-->fox-->hawk
2:ocean/marine ecosystem
biotic: fish, seaweed, plankton
abiotic :water, rocks, sunlight
Explanation:
<span>The correct answer is B. Melting of glaciers. Glaciers are not salt water so adding them to the sea would reduce the salinity of the sea. Similar thing occurs when rivers flow into the sea or the ocean. Evaporating would make it more salty because the water would leave while salt would stay meaning there would be less water and more salt.</span>
