C. Dependent variable
The independent variable is what you want to change (ex amount of light given to plants)
The dependent variable is what changes because of the independent variable (ex the height of the plants)
So Independent is what you change, Dependent is what you measure
It's the nucleus or the nucleolus to be exact which produces rRNA which as a structural component of ribosomes.
Hope i helped!
The epithelial cell will have 38 chromosomes
A 2n or 2(19) = 38 chromosomes. This is because n is called haploid number of chromosomes; the number of chromosomes present in the gametes. Epithelial cells like other body cells divides through the process of mitosis; therefore; the parent cells yields daughter cells with the same number of chromosomes (diploid). The other haploid (n) number is present in the gametes which divides by the process of meiosis.
