  1. In a Missouri forest food web, oak trees produce acorns eaten by squirrels, which are eaten by red-tailed hawks. What role do the oak trees play?

    Answer: Producers

    Oak trees make their own food through photosynthesis, so they are producers.

  2. Which organelle is the site of cellular respiration in plant and animal cells?

    Answer: Mitochondrion

    Mitochondria break down glucose to release usable energy (ATP).

  3. A pea plant heterozygous for tall stems (Tt) is crossed with a short plant (tt). What percentage of offspring are expected to be short?

    Answer: 50%

    A Tt × tt Punnett square gives 2 Tt and 2 tt, so 50% are short.

  4. Which process allows a population of bacteria to become resistant to an antibiotic over time?

    Answer: Natural selection of bacteria with resistant traits

    Bacteria that already carry resistant variations survive and reproduce, increasing resistance in the population.

  5. Zebra mussels, an invasive species, have spread in Missouri waterways. What is the most likely effect on native mussels?

    Answer: Increased competition for food and space

    Invasive zebra mussels outcompete natives for plankton and attach to them, reducing native populations.

  6. During photosynthesis, which substances are the main reactants?

    Answer: Carbon dioxide and water

    Plants use carbon dioxide and water, with light energy, to produce glucose and oxygen.

  7. Which type of cell division produces gametes with half the number of chromosomes of the parent cell?

    Answer: Meiosis

    Meiosis produces haploid gametes (sperm and egg) for sexual reproduction.
