How does the lens of a light microscope work?
Each concave lens bends light to make the object appear larger.
each convex lens bends light to make the object appear larger.

DNA
Ribosomes
Nucleus
Mitochondria
A scientist discovers a cell that has chloroplasts, cytoplasm, DNA, and a cell membrane. Which statement best describes how the cell could be classified?
The cell is prokaryotic because it has DNA.
The cell is prokaryotic because it has cytoplasm.
The cell is eukaryotic because it has a cell membrane.
The cell is eukaryotic because it has chloroplasts
The endosymbiotic theory provides an explanation for the origin of chloroplasts. Which trait of chloroplasts supports this explanation?
Chloroplasts do not reproduce.
Chloroplasts have their own DNA.
Chloroplasts rely on proteins that are made by the cell.
Chloroplasts are larger than prokaryotic cells.
How is mitochondrial DNA (mtDNA) typing used in forensic science?
A suspect’s mtDNA sample is matched to an unknown sample of nuclear DNA that was found at a crime scene.
A suspect’s mtDNA sample is matched to an unknown sample of mtDNA that was found at a crime scene.
A suspect’s nuclear DNA sample is matched to an unknown sample of nuclear DNA that was found at a crime scene.
