Answer:
Two plates pushed together create a convergent fault. If one plate is oceanic and the other continental, the edge of the oceanic plate will be pushed down. When two plates move away from each other they create a divergent boundary. When this happens under oceans, new ocean floor is created.

Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae. Nutrients can run off of land in urban areas where lawn and garden fertilizers are used
Explanation:
The domain Eukarya evolved from the unicellular organisms, and the proof of this can be derived from the endosymbiotic theory. According to this theory, the organelles, such as mitochondria and chloroplasts were previously free-living organisms. This is supported by the fact that the mitochondria and chloroplasts have their own DNA (deoxyribonucleic acid).
Hence, the answer is 'Option C - mitochondria and chloroplasts have their DNA.'
Question: If they aren't hermaphrodites, can they still be male and female at the same time?
Facts: Different snails reproduce differently, but most snails are "hermaphrodites." Being a hermaphrodite means that any given snail can be both male and female at the same time. This can make it a lot easier for snails to reproduce and quickly make a whole lot of snails! Some hermaphrodite snails do not need another snail to reproduce, but can make more snails all by themselves (this is called asexual reproduction). Other snails are hermaphrodites but still need another snail to reproduce (this is called sexual reproduction). There are also some snails that aren't hermaphrodites, but are either male or female, and must find a snail of the opposite sex to breed with.
