Answer:
evaporation of water is equal to precipitation of water
Explanation:
The hydrologic cycle maintains a balance of Earth's water because evaporation of water is equal to precipitation of water
Answer:
There are two types of photoreceptors in the human retina, rods and cones. Rods are responsible for vision at low light levels (scotopic vision). ... Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity.
I'd say C, because the experiment would consist of cutting the tall plant to see if the trait of now being short (which is actually not a trait, you can't change genes like that, cutting the plant does not alter DNA or genes in any way.). So that would result in controlling for the plant's experiences before pollination. (does that make sense?) Basically they're testing for the plant's ability to pass on its life experiences to its offsprings.
Carbon is released back into the air when a living thing exhales carbon. For example, humans breathe in oxygen and exhale carbon.
