What are two important differences between the life cycle of a typical fern and that of a seed plant?
gametophyes is one difference
The Calvin Cycle and the Kreb's Cycle have similarities and differences. First, both cycles start with the same molecule as they end with. The Calvin Cycle starts and ends with a ribulose biphosphate, while the Kreb's Cyle starts and ends with an oxaloacetate molecule. Another similarity is that they both use energy. The Calvin Cyle uses energy to make sugar, while the Kreb's cycle produces energy to give to the next stage of cellular respiration.
they are totally different. the nitrogen cycle is how waste is converted by bacteria into ammonia, then nitrite, then nitrate, which is used by plants, and the plants are eaten, and pooped out. the water cycle is when water in a river goes to the ocean, then evaporates, then is rained onto the ground, then seeps into a river, etc.
