Ascientist is studying the inheritance of two characteristics in plants: red flowers (rr and rr) , which are dominant to yellow flowers (rr) , and green leaves (gg and gg) , which are dominant to yellow leaves (gg) . she crosses a double heterozygous (rrgg) with a double recessive (rrgg) , and expect to see a 1: 1: 1: 1 ratio in the offspring. instead, she sees these results: genotype rrgg rrgg rrgg rrgg predicted outcome 500 500 500 500 actual outcome 900 900 100 100 which phenomenon would she hypothesize accounts for the pattern she sees? crossing-over respiration cytokinesis independent assortment

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
