Answer:
The correct answer is : the female chromosome
Explanation:
- According to the question, it is mentioned that R is a dominant allele, responsible for the red eyes.
- RR is a genotype for Red eyes.
- A fruitfly has a diploid genotype which means each trait is represented by a pair of chromosomes.
- In the above question, the dominant red eye colour trait is represented by the pair of chromosomes RR.
- Therefore, XX must represent another trait.
- By convention, a pair of X chromosomes (XX) represent a female and a combination of X and Y chromosomes (XY) represents a male.
- Given XX genotype represent a female fruitfly chromosome.
Answer;
The nucleus.
Explanation;
-The nucleus is the cell organelle whose function resembles the function of the brain in higher animals.
-The Nucleus is the largest organelle in a cell. It contains a dense structure called the Nucleolus and is surrounded by the Nuclear Envelope.

Answer:
4
Explanation:
the ocean covers 70% and land covers 20%
The answer is A. point mutation which does not change the amino acid. A point mutation is a mutation of gene in which a single nucleotide is changed from the sequence. In this case, the amino acid was replaced by the same amino acid in which there will be no effect on the product of the sequence. This will not alter the replicated DNA, Product that will be produced will be essentially the same.
Funny thing is idk this one but I need the points lol :)
