How can nearly all energy on earth be tracked back to nuclear fusion?
Answer: see if this helps Nuclear fusion seems a great solution for the demand of Energy. It is safe, has infinite fuel, produce a negligible amount of waste etc.There are enormous technical challenges still to overcome, but let’s assume one moment, for the sake of the argument, that we find a way to solve them and the power plant is now “technically ready”.Reading around seems that the cost of such plant will be huge: a lot of material required, complexity in the construction etc. Such construction costs include a very relevant energy price. For instance digging all the material and “transform” them requires a lot of energy. I have the feeling that the energy produced all over the life cycle has the same order of magnitude: i.e. at the end the “net balance” is not so convenient. Considered the huge capital cost the ration “Net energy produce / cost” would be quite poor as well.

What do you think Newton meant when he said, “If I have seen further [than most people], it is by standing on the shoulders of giants”?
Answer:
Newton meant to say that even the biggest scientist had made mistakes and so did he in his experiemnts and that they all learned from each others ideas
Newton intended to imply that even the most accomplished scientists made errors, just as he did in his experiments, and that they all benefited from one another's insights.
What do you think Newton meant?The term is considered to suggest that Newton was working in the context of findings made by previous scientists, either in his own time or earlier.
If I have seen further, it is because I have been supported by giants. Since it occurred in a letter he addressed to fellow English scientist Robert Hooke on February 5, probably in 1675 or 1676, this quotation has been credited to Sir Isaac Newton.
Describing how his innovations (and those of others) were made possible by the fact that they built on earlier concepts and accomplishments.
Therefore, There is no disputing that Newton is the author of this statement.

Examine the words,
impulse, presynaptic cell, neurotransmitters, receptors, postsynaptic cell,
What idea can be described using all the words listed?
The synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.
What is synapse?It is the functional relationship of contact between the endings of nerve cells.
This communicative process between neurons begins with a chemical-electric discharge in the membrane of the emitting cell (presynaptic cell).
When said nerve impulse reaches the end of the axon, the neuron secretes a substance that lodges in the synaptic space between this transmitting neuron and the receiving neuron (postsynaptic cell), in turn, this neurotransmitter is responsible for exciting another neuron.
Therefore, we can conclude that the synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.

Mitosis and Binary Fission are very similar except when comparing the size of the new daughter cells relative to the original parent cell.
True or false?
Answer:
Explanation:
False sorry if it is wrong
Mitosis and Binary Fission are very similar except when comparing the size of the new daughter cells relative to the original parent cell is a false statement.
What is Mitosis?A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase. The cell's contents are often evenly divided into two daughter cells with identical genomes after mitosis.
A cell copies each chromosome during mitosis and distributes one copy to each of its two daughter cells. With regard to our example of an instruction manual, it is crucial that each person receive a duplicate of each page.
Mitosis follows the same pattern. Each chromosome must be delivered to each of our cells exactly once, without any errors, or the cells may have problems carrying out the genetic instructions.
Therefore, Mitosis and Binary Fission are very similar except when comparing the size of the new daughter cells relative to the original parent cell is a false statement.
