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.
The workers can be
protected by "trench box". Trench shields which are known as
Trench Boxes or Trench Sheets as well, are steel or aluminum structures
utilized for securing utility laborers while playing out their obligations
inside a trench. They are generally developed with sidewalls of changing
thicknesses held separated by steel or aluminum spreaders.
Answer:

Explanation:
Difficult children generally caused by the self-entitled feeling that the child have to do or achieve something that they desire regardless of the consequences.
When parents tried to communicate with this type of children, they tend to response with intense answers (associated with stomping and screaming). To handle this, the parents need to take a risk and create some sort of negative reinforcement to discipline the children (does not have to be physical)
Answer:
The correct answer is c.
People who adjust their behavior to best fit the situation are called <u>high self-monitors</u>, and people whose behavior is guided by their personality are called <u>low self-monitors.</u>
Explanation:
Mark Snyder's theory of self-observation tries to explain how we adapt our behavior to the social context and how it is related to aspects such as personality or patterns of social interaction. People who are high self-monitors exercise strong control over their external behavior and the image of themselves that they project socially; more specifically, they adapt to the characteristics of the interaction situation and the interlocutors. On the other hand, those who have a low level of self-monitoring try to maintain coherence between the vision they have of themselves and the one they project to others. Thus, they show consistent social patterns, tend to express their true thoughts and are not constantly concerned with how they can be evaluated.
The correct answer choices should be A.) The maniple was a flexible military unit and C.) The Roman soldiers built roads and bridges. Hope this helped!
