Eukaryotic cells differ from each other due to their structure and function. Though, two eukaryotic cells could differ in the number and types of organelles they contain.
The myelin sheath is the layer of fat cells that insulates most axons and speeds up the transmission of nerve impulses.
The correct answer is: D) H2O… CO2
Redox reactions are reactions of reduction (molecules tend to gain electrons) and oxidation (molecules tend to lose electrons).
Photosynthesis is a set of redox reactions. In photosynthesis electrons are removed from water (H2O) to carbon dioxide CO2 and then used to turn CO2 into organic compounds.
The first step: Oxygen in water is oxidized (light energy required)
The second step: Carbon in CO2 is reduced; sugar is formed (dark reaction).
During the mature stage this happens because the air becomes more dense.
