The answer is A. True
Which of the statements below is true about the alleles for eye color in fruit flies?
A)
The alleles for eye color produce the same phenotype.
B)
The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly.
C)
Changes in the sequence of DNA bases in a gene do not contribute to genetic variation in the fruit fly population
Answer:
The correct answer would be B) The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly.
The amino acid sequence of any protein is determined by the codon sequence of the mRNA which is in turn determined by the nucleotide sequence of the DNA.
Thus, if the nucleotide sequence of the DNA is changed, it will result in the change of amino acid sequence of the protein.
It may result in the change of the structure as well as the function of the protein.
Thus, if the sequence in the gene is changed slightly, it would not result in the production of protein required for a red color trait.
Hence, the eye color of the fruit fly would change to white.
Part I
In extension to measuring the amount of light that enters the eye, the pupillary light reflex presents a helpful diagnostic tool. It provides for examining the uprightness of the sensory and motor functions of the eye. if your pupils didn't shut suddenly when abruptly disclosed to light, you'll get a tremendous shot of light (simultaneously with UV rays and other possibly dangerous rays) to your retina, which can severely mess up your vision.
Part II
Without it, we would go blind. If there is not sufficient light and the pupils do not dilate, a small number of light will pass to the retina and the image will be damaged.
Answer: Ionic Bond
Explanation: A metal and a non-metal bonding together create an ionic bond.
To modify the model of a given animal cell into a plant cell, it is required to add the cell wall around the cell membrane. It is also mandatory to construct large vacuoles in the cytoplasm with cell organelle chloroplast.
Plant cells may be defined as the type of eukaryotic cell that are the basic unit of life in organisms of the kingdom Plantae such as green plants, photosynthetic algae, etc.
The diagram illustrates the animal cell and asked to modify this into the plant cell. So, there is a requirement to add or edit this cell with plant cell organelles and its characteristics like cell wall, presence of chloroplast, large central vacuoles, etc.
Therefore, it is well described above.

Answer:
To show the structures of a plant cell, add a cell wall around the membrane and increase the size of the vacuole inside the cell. Draw green ovals to represent chloroplasts.
