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).
Photosynthesis is the process of using (energy, eggs) from (light, chickens) to synthesize (sugars, corn) which then. can (store, eat) this energy. Photosynthesis requires (light, horse) energy, carbon dioxide, and (water, snow cones) to make glucose (sugar), oxygen, and water.
