In eukariotes, cells that have a neculeus, the dna is found in the neculeus, not the cytoplasim so that is false... I dunno if that is what u were asking...
The answer is; A
When an impulse from the motor neuron reached the neuromuscular junction, the voltage-dependent calcium channels are activated and the neurotransmitter released from the presynaptic cleft. When the neurotransmitter binds to their receptors on the sarcolemma, the muscle fibers become depolarised; the calcium is released from their vesicles. The Ca2+ ions are important in the power stroke because they bind to troponin. Upon binding calcium, troponin moves tropomyosin away from the myosin-binding sites on actin. Powered by the energy from ATP molecule, the myosin is able to bind on the actin and slides over the actin filament.
Answer:
I think the answer is B
Explanation:
Because using logic on this situations is best idk
Eukaryotes are organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes. Eukaryotes belong to the domain Eukaryota or Eukarya.
