1. Which pair of structures best shows that plant cells have functions different from animal cells?
Show answer
Answer: B — Chloroplasts and cell walls
2. One strand of DNA could be as long as a football field if it were stretched out lengthwise. One of the factors allowing DNA to fit inside the nucleus of a cell is its ability to —
Show answer
Answer: C — coil tightly around associated proteins
3. Two plants are crossed, and the traits of height and color are assessed in the offspring. The cross conducted is TTPP × ttpp, where: T = dominant allele for tall height t = recessive allele for short height P = dominant allele for purple color p = recessive allele for white color Which of the following choices correctly describes the offspring?
Show answer
Answer: D — All plants are tall and purple.
4. In an experiment, the height of several plants was recorded daily in millimeters. Which tool would be the most accurate and appropriate for this measurement?
Show answer
Answer: D — Metric ruler
