Answer:
Ability to perform locomotion with their legs
Explanation:
Plants and animals are two distinct species of organisms. Plants are capable of using photosynthesis to obtain their food due to the unique structures that can capture light energy in their cells (autotrophic). Animals, on the other hand, are heterotrophic i.e. cannot perform photosynthesis and therefore, rely on other organisms for food.
Since animals depends on eating other organisms to obtain food/energy, their possession of LEGS or ability to LOCOMOTE is very instrumental to their success as non-photosynthetic or heterotrophic organisms. This enables them leave one position in search for food and resources
C. The nervous system sends signals to make muscles move.
I would say B because A doesn’t have a ring to it.
The only independent variable in this experiment is the amount of nitrogen Sarah uses. All of the other variables are dependent on other factor and processes, but Sarah controls the amount of nitrogen that she uses for each plant.
