Approximately 80% of HIV diagnoses in the USA are among people who become infected through sexual exposure. Thus, of the approximately 40 000 new HIV infections each year in the US, 32 000 are sexual transmissions. Our results indicate that the HIV-positive unaware group contributes disproportionately to these new infections relative to their percentage of the HIV-positive population in the USA.
Dark red and blue-green indicate regions of high photosynthetic activity in the ocean and on land, respectively. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities (energy transformation).
Rating Newest Oldest. Best Answer: Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy, CO2, and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll, the green pigment involved in photosynthesis. The energy transformation that occurs during photosynthesis is solar energy to heat energy. During photosynthesis light energy is converted into chemical energy. 1.Conversion of light energy to chemical energy. 2 .Splitting of water molecules into hydrogen and oxygen.
