Answer:
The correct answer would be C. The tortoises provided evidence that different species have adaptations suited to their particular environments.
Darwin observed that how different environment on different island lead to the development of different species as a result of adaptations and natural selection.
For example, tortoise inhabiting well-watered islands which used to have short and cropped vegetation had developed a dome-shaped shell.
In contrast, the tortoise inhabiting the arid islands had developed saddle-shaped shells. It is because they needed to stretch their necks in order to reach branches of cactus and other vegetation available in the area.
Consequently, they developed long necks and high peak to the front edges of their shells. It made it possible for them to stretch their heads vertically.
Answer:
yes
independent - temperature
dependent - amount of sugar dissolved
Explanation:
When water molecules are heated they move faster and collide more with the sugar molecules. These collisions transfer energy to the sugar molecules. Energy is needed to break bonds. The bonds holding the sugar molecules together or more likely to be broken.
The amount of sugar dissolved is dependent on the temperature of water.
