Which organelle is the primary site of ATP (energy) production in most eukaryotic cells?
Understanding organelle function is fundamental to cell biology and energy metabolism.
What is the main role of the cell membrane?
Consider the membrane's role in maintaining internal environment and selective transport.
Which base pairs with adenine (A) in DNA?
Recall complementary base pairing rules in DNA structure.
What does Mendel's law of segregation describe?
Basic Mendelian genetics and allele behavior during reproduction.
Which organisms are primary producers in most ecosystems?
Producers form the base of energy flow in ecosystems.
What is the typical outcome of mitosis in a somatic (body) cell?
Mitosis is essential for growth and tissue repair.
Which macromolecule is a primary short-term energy source for cells?
Different macromolecules have distinct biological roles.
What does biodiversity describe?
Biodiversity is a key concept in ecology and conservation biology.
Natural selection is best described as:
Fundamental evolutionary mechanism shaping populations over time.
Which statement best describes viruses?
Basic virology and how viruses differ from cellular life.
What is the primary purpose of PCR (polymerase chain reaction)?
PCR is a cornerstone technique in molecular biology.
If an individual is homozygous for a gene, what does that mean?
Basic genotype terminology.
