During metabolic reactions, an electron source : a) gets oxidized; therefore you must reverse the reaction you look up in the redox tower.
b) gets reduced; therefore you must reverse the reaction you look up in the redox tower.
c) gets oxidized; therefore you must NOT reverse the reaction you look up in the redox tower.
d) gets reduced; therefore you must NOT reverse the reaction you look up in the redox tower.

a. possible errors

d. new questions

explanation:

predictions and planning happen before. a summery comes after. errors you get after investigation and new questions propose what you can look for in the future.

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint

carbon atoms, hydrogen, oxygen, and nitrogen.

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.
