Earlobes may be free or attached, as shown in the illustrations below. The type of earlobe a person has is genetically determined. The allele for free earlobes (E) is dominant, while the allele for attached earlobes (e) is recessive. The inheritance of the earlobe trait can be traced over several generations using a family tree called a pedigree. A pedigree for the earlobe trait is shown below. (QUESTION) If female #3 and male #4 were to have another child, what would be the probability of that child having attached earlobes? answers:
1/4
1/2
3/4

Could you elaborate?

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.

Ineed the answers so i can you
