The carbon that plants need for photosynthesis comes from (carbon dioxide gas in the atmosphere)
It should be C! (: Fate mapping because it is used do dermine tissue linage!
While Differentiation is used when one cell type changes from one cell to another.
When it comes to the process an undifferentiated cell is already programmed to become a specific cell type by following a specified path towards cell differentiation.
I hope all is well, and you pass! (: Good luck, rockstar! If you need any further information, let me know. (:
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.

Cosmology is a branch off of astronomy, cosmology is the study of <span>large scale properties of the universe as a whole. Astronomy is the study of celestial objects, such as stars, planets, galaxies, etc. </span>
