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).
<span>Algae bloom or algal bloom is an obvious appearance or rapid
increase and accumulation of millions of algae and tiny plant-like organisms in
the water. The blooms of these microscopic algae or phytoplankton is the result
of abundant sunlight, nutrients, and the right water conditions. These blooms may take place in freshwater and
in marine environments as well. They come in different colors, cyanobacteria
blooms for instance are often blue-green which literally means that blue-green
algae comes to bloom</span>

Answer:
1: 7.8 cm
2: .7 cm
3: 5.55 cm
For the other questions, you have to use a ruler yourself and measure using cm. :)
1 cm = 10 millimeter. To convert, just add a 0 to the end of cm to find the mm (or move the decimal one place to the right.)
For example, 2.6 cm = 26 mm / 5 cm = 50 mm. Hope this helps!
