Tara's friend, sally, came to school with a cold and sat in the desk next to tara's all morning blowing her nose. at lunch, they went outside to sit in the sun and eat. sally blew her nose again and then gave tara her cookie since she didn't feel like eating it. tara ate it and then carried sally's things back inside for her. several days later tara came down with the cold. at what point was it most likely that the virus infected tara?

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
