Answer:

The distribution of chloroplasts in each algae cell was approximately the same.

The number of bacteria grouped at each wavelength (color) was approximately proportional to the amount of oxygen produced by this part of the algae.

Explanation:

Photosynthetic pigments absorb blue, red and green lights. The wavelength of light that is the most effective in driving photosynthesis is 420 nanometers, which corresponds to blue light.

The wavelength of 475nm and 650nm are most effective in driving photosynthesis.

Reactions that require CO₂ take place in ________.
Alex787 [66]

Answer:

The correct answer is: A) the Calvin Cycle alone.

Explanation:

These reactions happen in cells capable of photosynthesis.

The only out of these reactions that require CO2 to take place is the Calvin Cycle. The Calvin Cycle is a series of biochemical processes that occur in the chloroplasts during photosynthesis. <u>The Calvin Cycle uses carbon dioxide (CO2) and water to produce glucose</u>, which will give energy to the cells.

The light reactions occur during photosynthesis in the presence of light and involving photophosphorylation. The light reaction does not make use of CO2, as it takes solar energy and converts it into NADPH and ATP.

Explain why it is important to create experiments that are reproducable by other people.
spayn [35]

Answer:

Reproducibility is important because it is the only thing that an investigator can guarantee about a study. Contrary to what most press releases would have you believe, an investigator cannot guarantee that the claims made in a study are correct (unless they are purely descriptive) So reproducibility is important not because it ensures that the results are correct, but rather because it ensures transparency and gives us confidence in understanding exactly what was done.

2. Give ONE possible reason, biotic or abiotic, why the population decreased in 1990
klemol [59]

Answer:

availability of resources.

Explanation:

Availability of resources is abiotic factor which is responsible for the decrease in population in 1990 because when the population reaches its carrying capacity so the organisms compete with each other and due to limited resources such as food etc the decrease occurs in population. Infection is also occurs when there is high population due to which death occurs and population of organism decreases.
