The similarities between a prokaryotic and eukaryotic cell is that they both have a plasma membrane, cytoplasm, and ribosomes. The difference is that the eukaryotic cell is usually larger and has a true nucleus. It has other membrane bound organelles.
Answer:
The Caenorhabditis elegans dauer state is a hibernation-like state of diapause that displays a dramatic reduction in spontaneous locomotion.
Explanation:
Mutations affecting the neurotransmitter dopamine, which regulates voluntary movement in many organisms, can stimulate movement in dauers. The movement of quiescent animals is stimulated by conditions that reduce dopamine signaling and also by conditions predicted to increase dopamine signaling.The stimulation of movement by increased dopamine is much more pronounced in quiescent daf-2(−) dauer and dauer-like adult animals.
In C. elegans hermaphrodites, dopamine is produced by eight neurons and signals via at least four dopamine receptors, DOP-1 through DOP-4. In addition, a presynaptic reuptake transporter, DAT-1, removes dopamine from the extracellular space to terminate signaling. In C. elegans, dopamine is best known for mediating the “basal slowing response” in which the animal's movement slows when it encounters food.. Dopamine is thought to be released in response to food and to act on motor neurons to modulate the animal's movement . Animals that cannot produce dopamine fail to slow in response to food and exogenous dopamine slows the movement of animals cultured without food.The response to dopamine in this situation is complex, as the absence of specific dopamine receptors can have either positive or negative effects on movement.

Answer:
The Empire of Great Britain had a "global power," which was also known as a "superpower" concerning resources, influences and geopolitical landscapes.
Explanation:
<em>When it comes to international relations, the power of a country or a nation is very important.</em> It is an inherent goal that many people want. It can be used in many situations such as<em> cooperating with other countries, coercing people to follow a rule, securing the nation and developing the nation, etc.</em>
The Empire of Great Britain was considered, together with USA and the Soviet Union, to have a "superpower." Only the strongest nation possess such power. It was able to control millions of people, which then resulted into a great expansion. <em>The reason behind this is that they had a stricter rule than other nations and people followed it.</em> This made them stronger and while they continued expanding, they were able to acquire more resources.
Bacteria have either DNA or RNA as genetic material. This genetic material must be able to replicate efficiently and accurately in order to make sure that offspring inherit the same genotype as the parent organism. This is possible because of genetic information.
