Proteins
Nucleic Acids
What structure is found in viruses but not in cells?
RNA
Proteins
Capsid
DNA
What structure is most likely found in both viruses and cells?
Ribosomes
Proteins
Cytoplasm
Vacuoles
Which of the following statements accurately describes a difference between viruses and bacteria?
Viruses are much smaller than bacteria cells.
Viruses have a higher metabolism than bacteria cells
Viruses contain organelles while bacteria cells do not
Viruses reproduce asexually while bacteria cells reproduce sexually
Most viruses have the structural arrangement of
a cell wall surrounding the cell membrane
a capsid shell made from lipids
flagella surrounding the cell membrane
a capsid surrounding a nucleic acid sequence
What is one of the functions of nucleic acids?
Stores genetic information and helps to make proteins
Increases the rate of chemical reactions
Stimulates metabolism in all body cells
Activates secretion of the body's hormones
What evidence best supports the Endosymbiotic Theory, which states that current cell organelles like mitochondria and chloroplasts were once prokaryotic cells consumed by other prokaryotic cells?
Mitochondria and chloroplasts can break away and live on their own without the host cell.
Mitochondria and chloroplasts act as parasites inside the host cell.
Mitochondria and chloroplasts have DNA coding different from the nuclear DNA.
Mitochondria and chloroplasts are both performing the same function.
Based on cell size and complexity, prokaryotic cells would be expected to —
have more ribosomes than most eukaryotic cells
have fewer ribosomes than most eukaryotic cells
be affected more by DNA mutations compared to eukaryotic cells
be affected less by DNA mutations compared to eukaryotic cell
Which structures are found in all prokaryotic cells?
Flattened, stack-like structures which process macromolecules
A continuous, interconnected network of membranes
Small, protein-producing units composed of RNA and protein
Power-producing organelles that convert energy into usable forms
Which statement applies to eukaryotic cells but not to prokaryotic cells?
Utilize mitochondria during energy production
Flow of nutrients and wastes occurs across a membrane
Contain DNA as genetic material
Perform metabolic processes with the help of chemicals
Which structure is not present in a prokaryotic cell?
DNA
Nuclear membrane
Phospholipid membrane
Cytoplasm
Which structure can be found in both eukaryotic and prokaryotic cells?
