Fireflies flicker and flash as they dart through their mating dances, all the while transforming a lovely summer night into a magical evening. While the bioluminescence that allows these insects to glow and gain the moniker “lightning bugs” creates wonder in humans, it is a not-uncommon feature in the animal world, especially for fish and other marine species.
National Geographic defines bioluminescence as light that occurs from the reaction between two chemicals within a living organism: the compound luciferin and either luciferase or photoprotein. The ability to produce light is not just a flashy feature; bioluminescence can give the animal a competitive advantage. For example, deep-sea vampire squids eject glowing mucus to startle predators, and hatchet fish use light-producing organs to adjust reflections off their bodies, masking themselves to prey who are hunting them from below. Other animals that glow or flash to get ahead at sea and on land include plankton, coral, and glowworms.
For decades, scientists and medical researchers studied bioluminescence in nature and have adapted fluorescent genes as biomarkers for many applications. That is how GloFish found their way into home aquariums across the country.
Answer:
<h2>D. Negative attention bias</h2>
Explanation:
The way a persons perception is affected by various factor in their attention is called attention bias.
It is a person's failure to consider alternative possibilities when occupied with existing thoughts. As it happens in smokers, they have attention bias for the cues and warning about smoking around them as their brain alters their reward sensitivity.
Similarly Rachel is also biased and only focused on the negative critique instead of positive comments so she is engaged in negative attention bias.

1. ANSWER: The Code of Hammurabi
Hammurabi set up the "Code of Hammurabi" with 282 laws and where the famous phrase "an eye for an eye, a tooth for a tooth" came from. Although this code is actually more complex and less sinister-sounding than the phrase (which is not a direct quote, by the way), this legal system is meant to protect everyone abused, offering just compensation to everyone harmed.
In this system though, the accuser has to be the one to bring the accused to trial.
2. ANSWER: He wants to protect the abused.
Since Hammurabi was ruling a very diverse set of people, he set out to find a set of universal laws to govern everyone. He tapped legal experts to collect previously existing laws and examine them until he formed the Code with 282 laws.
Quoting Hammurabi directly, he said that he set out these laws "to make justice visible in the land, to destroy the wicked person and the evil-doer, that the strong might not injure the weak."
3. ANSWER: The laws influenced future cultures.
The Code of Hammurabi is often attributed as the first set of written laws to be uncovered. Although this may not be the case as there are older laws that were uncovered, being recognized as the first set of written laws often led leaders of future cultures to adopt the system, making these leaders lead the way Hammurabi led.
