Mitochondria
Nucleus
Chloroplast
Endoplasmic Reticulum
Reasoning - These are specialize Organelle which function in each part of doing their duty require the layers to keep it separate in maintaining certain materials they receive within the cell.
Answer:
B
Mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well Because prokaryotes are haploid, such a mutation immediately become part of the genetic makeup of the cell unlike eukaryotic diploids where a normal second copy of the gene usually protects the cell from the potentially lethal effect of such a mutation.
