Question

Which of the following could be evidence that an organism's growth is influenced by the organism's environment?
The average height of an oak tree in northern Texas is much less than the average height of the same kind of oak tree in northern Indiana.
Two different kinds of grass are grown in neighboring yards. One yard has to be mowed much more often than the other.
Plants grow taller and more quickly when given the right amount of light and water.
A breed of cattle can be made larger by breeding together only the largest cows and bulls
. all that apply

Answer 1

Answers:
- The oak trees in northern Texas vs northern Indiana — Yes. (Same species shows different growth in different environments → environmental influence.)
- Plants grow taller and more quickly with the right amount of light and water — Yes. (Direct effect of environmental factors on growth.)

The other two describe genetic differences or selective breeding, so they are not evidence that growth is influenced by environment.
