4. Root cells of plants take in some minerals from the surrounding soil by spending energy. After the plant obtains enough minerals to maintain health, the plant will
continue to absorb minerals from the soil. Which reason best explains why root cells
need to spend energy in order to transport some minerals into cells?

Solar energy causes water to evaporate into the atmosphere. how does that water vapor become a cloud? a) as the water vapor goes higher in the sky, the air gets cooler. the cooler air causes the water vapor to condense. b) as the water vapor goes higher in the sky, solar energy causes it to condense around particles of dust. c) as the water vapor goes higher in the sky, the air gets warmer and the water vapor begins to condense. d) as the water vapor goes high into the atmosphere it turns to ice and that's what forms clouds.
