Answer:
b
Explanation:
Alkenone molecules from phytoplankton are robust enough to survive the effects of weathering and chemical breakdown for 110 million years. Rock layers yield chemical traces of these ancient organisms. Their chemical composition indicates ancient water temperatures.
Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
If Algae is one of the answers it algae
The clear fluid found in whole blood in which the cells are suspended is called <u>plasma </u>however, when the clotting factors are removed, it is now called <u>serum</u>.
Plasma is the frequently forgotten part of blood. White blood cells, red blood cells, and platelets are essential to body characteristics. However, plasma also plays a key function. This fluid consists of the blood components during the frame.
The serum consists of all proteins not utilized in blood clotting; all electrolytes, antibodies, antigens, hormones; and any exogenous substances (e.g., capsules or microorganisms).
Serum does now not incorporate white blood cells (leukocytes), red blood cells (erythrocytes), platelets, or clotting elements.
