Answer:
The correct answer is- It is used to produce glucose molecule
Explanation:
Photosynthesis is a process in which light energy is captured by chlorophyll which is then used to convert carbon dioxide and water into glucose. Oxygen is also produced as a by-product in this process.
The light energy is used to split water into oxygen, hydrogen ions and release electrons from it. The electrons pass through many electron carriers through photosystem II and I and ultimately reduce NADH+ to NADPH which is used in the Calvin cycle to produce glucose.
Therefore glucose is produced by the help of light energy captured during photosynthesis.
Answer:
The correct answer is A)
To limit the potential flooding damage that could result if an earthquake happens and the dam spills over
Explanation:
According to the text, seismic risks are very high for dams in that region. One of the reasons is that some of the dams were built many years ago when civil engineers didn't have information about what an earthquake could do to dams.
Citing an occurrence that happened in 1899 as an example where thousands of people were killed as a result of a failed dam, it is feared that should same reoccur, the loss may be more because about 300,000 people occupy the flood zone along the Alameda Creek below the dam.

Explanation;
Soil erosion is the wearing away of a field's top soil by the natural physical forces of water and wind or through forces associated with farming activities. Preventing top soil erosion is critical in agriculture; this is normally done using various measures such as Planting grass and shrubs, mulching, avoid soil compaction among other methods.
