Short Answer
16. the type of soil in which each seedling is
planted
17. independent variable: type of soil used;
dependent variable: height of plant;
constant: type of seedling used
18. qualitative
19. Answers will vary. Possible answers: In ten
days, a tomato seedling will grow taller in
potting soil than it will in either sand or
clay.
20. The experiment lets you plant the seedlings
in different types of soil and compare the
height of the plants.
21. adaptations
22. Birds with a particular shape or size of beak
must have been successful because the beak
allowed them to eat particular foods in their
environment. Those birds were more likely
to survive and reproduce and pass on the
beneficial trait.
23. Bird B; because it eats cactus
24. Bird A; because it eats insects
25. They would not compete for the same foods
because each is adapted for a different type
of food: finch A eats insects; finch C eats
seeds; and finch D eats buds, leaves, and
fruit.
