Answer:
Transposon is a fragment or sequence of DNA that can move unregulated to any point in the cell genome, leading to a phenomenon called transposition.
Explanation:
Transposon is the name of what was previously known as jumping genes, being a DNA sequence capable of moving freely within a DNA molecule. A transposon can produce mutations by translocation, altering the total amount of nucleotide in DNA molecule.
Genetic changes that are linked to evolutionary processes can be due to the existence of transposons, since they can even induce chromosomal changes.
Next, Rodrigo performed the same test with different amounts and different concentrations of the ammonium chloride solution. For each set of measurements, he found the lowest temperature reached by the bottle of water and calculated the total temperature change. The table below summarizes his results.

Rodrigo wants to find more ways to improve his latest design. Which of the following should he try?
(CHOOSE ALL THAT APPLY)
A - a more concentrated solution
B - a less concentrated solution
C - better insulation
D - less insulation
E - a greater amount of solution
F - a lesser amount of solution
Temperature measures the average kinetic energy of particles of the substances. Therefore, the correct option are option C,E that is better insulation and a greater amount of solution.
Temperature is used to measure degree or intensity of heat of a particular substance. Temperature is measured by an instrument called thermometer.
Temperature can be measured in degree Celsius °c, Kelvin k or in Fahrenheit. Temperature is a physical quantity. Heat always flow from higher temperature source to lower temperature source.
We can convert these units of temperature into one another. The relationship between degree Celsius and Fahrenheit can be expressed as:
°C={5(°F-32)}÷9
To improve his latest design Rodrigo should use a better insulation and a greater amount of solution.
Therefore, the correct option are option C,E.

Answer:
Better insulator.
A greater amount of solution
Explanation:
Answer: C) carbon dioxide and water.
Explanation:
It should've ranked coupled with the release of energy. Because carbon dioxide and water are released into the atmosphere as byproducts of cellular respiration couple with the release of energy.
