When a muscle cell contracts some myosin heads bind to actin molecules as other myosin heads release from actin molecules.
Muscle contraction occurs when the thick filament and the thin filaments slide over one another in a series of repetitive events.
Oh wait, I know which one you are talking about. The answer would be D. The G2 Phase. Hope this helped! :)
The punnett square is attached to this.
The other possibilities are AB, BO, and AO.
All of them have 25%.
Answer and explanation;
-Aba is a suitable replacement because Aba and Cys have approximately the same sized side chain and are similarly hydrophobic.
-However, Aba cannot form disulfide bonds so it will not be a suitable replacement if these are required.
-Alpha-Aminobutyric acid is biosynthesized by transaminating oxobutyrate, a metabolite in isoleucine biosynthesis.
in the earth's atmosphere is made up about approximately 78 percent nitrogen and 21 percent oxygen.
