Answer:
Water (H2O)
Explanation:
Light reactions of photosynthesis release oxygen as a by-product. In the presence of sunlight, photolysis of water molecules occurs. Splitting of two water molecules obtains four electrons, four protons, and molecular oxygen. The oxygen-evolving complex, also called the water-splitting complex is associated with photosystem II (PS II). Splitting of water occurs in the oxygen evolving complex and the released electrons are passed one at a time to the reaction center of PS II. Therefore, a water molecule serves as a source of oxygen released during photosynthesis.
Answer:
True (if this was a true or false question. Please specify next time. Hope this helps!)
Explanation:
Scanning acoustic microscope
A scanning acoustic microscope is a device which uses focused sound to investigate, measure, or image an object. It is commonly used in failure analysis and non-destructive evaluation. It also has applications in biological and medical research
I'm sorry to use an answer for this, but that last sentence doesn't make sense.
Answer:
Pump Ca+ into the cell.
Explanation:
The pumps are used for the transportation of substances against the concentration gradient. These pumps require energy for the transportation of molecules against the concentration gradient.
The most common pump used for the transportation of calcium ions is the calcium pump. These pumps require ATPase activity and transfer calcium against the concentration gradient. The calcium ions are pumped outside of the cell and not cell inside.
Thus, the correct answer is option (b).
