Hello Wtfiswrongwitmeh, using radiocarbon dating, or carbon dating, you can determine the age
of an organic object from the relative proportions of the carbon
isotopes it contains. Therefore, if you take the fossils form the fossil
record and determine how old they are, you can see how/if they evolved
over time.
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.
Specialized cells are formed when cells differentiate - this is true. When you have stem cells, you're talking about undiferentiated cells with no specific roles in the body. When these cells start differentiating and assuming different roles, they are also becoming specialized.
