Mitochondria are the energy factories of the cells. The energy currency for the work that animals must do is the energy-rich molecule adenosine triphosphate (ATP). The ATP is produced in the mitochondria using energy stored in food. ... This is a very efficient process for using food energy to make ATP.
A group of tissue that work together is a organ
As the population is possessing two phenotypes of the body color, it must then have at least two alleles for the gene of body color. As diploid (2n), each fly exhibits two alleles of the gene for the body color, one allele inherited from the father and one from the mother.
Therefore, a total number of alleles of the gene for the color of the body in the population is:
2 × population size, here 2 indicates each fly has two alleles of the gene, that is, 2 × 500 = 1000.
Hence, the total number of alleles of the stated gene in the population is 1000.
The answer would be 1,2,3, and 4
