what is concentration gradient
change in concentration from one location to another
Does cellular respiration absorb or release energy
releases
what takes place during metaphase
chromosomes align in the middle
what is homeostasis
regulation and maintenance of the internal environment: temp, fluids, salts, pH, nutrients, and gases
what are the 3 parts of a nucleotide
