What is mRNA?
Single-stranded RNAs of the type known as messenger RNA, or mRNA, are used to make proteins. mRNA is created during transcription from a DNA template.
The function of mRNA is to transport protein information from DNA in a cell's nucleus to the cytoplasm, or watery interior, where the machinery responsible for making proteins reads the mRNA sequence and converts each three-base codon into an amino acid that belongs in a protein chain that is expanding.
Therefore, UAU CGU GUA CAU is the mRNA sequence transcribed from this segment.

Different plant species require different amounts of direct sunlight in order to flower. A student designed an experiment to determine the length of exposure to direct sunlight necessary for a specific plant species to produce flowers. The student collected the data below.
0 hours, 0% with flowers
9 hours, 0% with flowers
1 hour, 0% with flowers
5 hours, 90% with flowers
3 hours, 80% with flowers
7 hours, 10% with flowers
Identify the:
independent variable-
dependent variable-
control group-
experimental group-
constant-
Answer:
Independent variable: LENGTH OF EXPOSURE TO DIRECT SUNLIGHT
Dependent variable: PRODUCTION OF FLOWERS
Control group: THE GROUP OF PLANT THAT WASN'T EXPOSED TO SUNLIGHT i.e. 0 hours
Experimental group: THE GROUP OF PLANTS THAT WERE EXPOSED TO SUNLIGHT
Constant: THE SAME PLANT SPECIES
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment. In this experiment, the experimenter exposes the specific plant species to sunlight at different length of time, hence, the LENGTH OF EXPOSURE TO DIRECT SUNLIGHT is the independent variable.
Dependent variable is the variable which is measured in an experiment. In this experiment, the measured/dependent variable is the PRODUCTION RATE OF FLOWERS by the plant species.
Control group is the group in an experiment that does not receive the variable being tested. In this experience, the control group is THE GROUP OF PLANT THAT WASN'T EXPOSED TO SUNLIGHT i.e. 0 hours
Experimental group is the group of am experiment that is exposed to the experimental treatment (sunlight). In this case, the experimental group is THE GROUP OF PLANTS THAT WERE EXPOSED TO SUNLIGHT.
Constants are variables of an experiment that must be kept unchanged for all groups throughout the experiment in order not to affect the experiment's outcome. In this experiment, the constant is THE SAME PLANT SPECIES used,

1- Evaporation:-
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. For more evaporation, the area that surrounds the surface of the water must be less humid i.e. it should not already be concentrated have the water vapors. For the evaporation we need to increase the temperature of the molecules of water on the surface, which is caused by the Sunlight.

Why is a red laser pointer an example of a poor blackbody radiator?
A. It glows less brightly as electromagnetic radiation is released.
O B. It gives off a range of wavelengths of electromagnetic radiation.
C. It gives off only one wavelength of electromagnetic radiation,
D. It keeps the same temperature and gives off no electromagnetic
radiation
A red laser pointer is a poor blackbody radiator because it emits electromagnetic radiation at only one wavelength. So, the correct option is C.
What is blackbody radiator?Depending on its temperature, a blackbody radiator is an object that radiates at different wavelengths. Blackbody radiation is the radiation that a blackbody radiator emits, and it exhibits a certain pattern known as Planck's law.
A red laser pointer, on the other hand, produces a narrow, focused beam of light at a specific wavelength, typically around 650 nanometers. This indicates that, unlike a blackbody radiator, a laser pointer does not generate radiation at different wavelengths. A red laser pointer is therefore a subpar blackbody radiator.
Therefore, the correct option is C.

What role does gene expression play in determining traits on an offspring? Explain your response
Gene expression has been defined as the process where the genes produce proteins and RNA. They determine the traits in offspring as various types of proteins pass from parent to offspring.
What is gene expression?Gene expressions are said to be the expression of the genome products in the cell that undergoes the process of transcription and translation to produce the RNA and protein structures that are responsible for providing the phenotype and genotype.
The genes code for the RNA and protein that regulates the amount and type of proteins to be expressed in the offspring that are passed from a parent through reproduction methods. They are hereditary patterns that vary in some amount to make two individuals different from each other.
Therefore, gene expression plays an important role in determining the trait in offspring.

Human Genome researchers discovered transposons. What are these structures?
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.

You have been provided with a non-polar liquid and are trying to determine whether
it is hydrophilic or hydrophobic. You place one milliliter of the substance into a
beaker filled halfway with water. Describe what will happen next.
Answer:
Explanation:
Non-polar liquids are liquids that have covalent bonds in which the shared electrons are shared equally. The molecules of these liquids are repelled by the molecules of water and hence do not dissolve in water. Thus, non-polar liquid are hydrophobic (water dislike/insoluble in water).
When one milliliter of the substance is placed into a beaker filled halfway with water, the substance will be seen "compact" (not dissolving nor interacting) in the beaker of water.
Polarity is defined as the separation of electric charge in a molecule or having an electric dipole moment due to the difference between negative and positively charged ends.
In the given experiment when one milliliter of the substance into a beaker is filled halfway with water, the substance will be seen as coagulating or not dissolving in the water.
The non-polar are the compounds or liquids that do not dissolve in the water. The non-polar molecules are the molecules, which are attracted to the alike molecules, rather than the water molecules.
The non-polar compounds have covalent bonds, in which the electrons are shared among the atoms of the compound.
The molecules of these liquids are repelled in the presence of water or are hydrophobic. These liquids do not dissolve in water.
Therefore, the liquid is hydrophobic.
