Answer:
The answer that are true are:
1) A: Horses and Mules can be bred but their offspring is typically sterile. This could be an example of hybrid breakdown.
2) C: One species of sea turtle mates during the early spring and a closely related species mates during late spring. This is an example of temporal isolation.
3) D: One species of sea urchins can not fertilize another closely related species because the eggs do not have a receptor for the sperm. This is a good example of gametic isolation.
4) E: Damselflies have sensory receptors that are sensitive to touch (tactile cues). Two related species of damselflies are unable to mate because their touch cues are not compatible. This is a good example of mechanical isolation.

Answer:
The carbon and water cycle I know, but I can't help with the nitrogen cycle. Sorry.
Explanation:
Carbon cycle - The role that plants play in the carbon cycle is that they take in our carbon dioxide and put out oxygen, which we breathe. So we give the plant air and they give us air.
Water cycle - The role that plants play in the water cycle is when it rains, the plants absorb some of the water in their roots, thus making them strong and therefore helping the ground not become a mud hole.
Sorry that I can't help with the nitrogen cycle. But I hope what I was able to help you with helps!
A cubit is an ancient measurement that measures length
the problem with using cubits is that the size may vary so it isn’t precise
the benefits of standardizing measurement is that they are precise and do not vary unlike the cubits
