Answer:
Cells are the basic structure and unit of life. There are prokaryotic and eukaryotic cells. Prokaryotic cells are very basic, and have no nucleus, few organelles, and are ususally bacteria. Eukaryotic cells are more complex and have nuclei, are larger compared to prokaryotic cells, more organelles, and have emembrane bound organelles. There are plant and animals cells, each have certain organelles that other don't. For example, plant cells have large vacuoles and a cell wall; animal cells have centrioles. Cells are important because they provide strucure for the body, and take in nutrients from food and carry out many important functions, such as protein synthesis, respiration, growth and development, and more. Billions of cells make up a complex organism's body, while a single cell can make up an entire organisms, and carry out all of the needed functions. That's a quick summary of what cells are, and some of the things that they do that make them so important
Explanation:
Regarding human traits, Locke would most likely agree with Aristotle.
There are more areas where Aristotle and Locke's philosophical views diverge than where they concur. For instance, Aristotle once claimed that a person's happiness was just as important to them as it was to their political community. The political understanding of Locke, however, is different because, in his view, a government only assumes responsibility for a portion of the human rights that it is meant to protect in accordance with what people deem to be right. Individuals are therefore given priority because they have rights that are inalienable and shouldn't be manipulated by people to fit their agenda. These and other traditional philosophies have been used to analyze and comprehend early philosophy.

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.
