what is the function of the structure indicated by the arrow
it oxidizes food to provide energy for the cell.
b)
it contains the cell's dna and controls celu processes
)
it serves as a site for protein synthesis and modification
d)
it is the site of synthesis of both white and red blood cells

Explanation:

B) It contains the cell's DNA and controls cellula processes

The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, as on units called chromosomes. ATP functions as a precursor molecule for more complex nucleotides.

Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good

explanation:

the fossil record provides evidence of a common ancestor to many species.
