Answer:
The correct answer is Zones of tolerance
Explanation:
All living organisms such as fish,plants and animals need water to survive and also the require certain pH level of water in order to be healthy.Its a acid and base balance reaction.Strong acids dissolve into water and its changes water's pH.if water's pH level drops it becomes acidic suppose a fish waste ammonia releases and dissolves in water to form harmless ammonia ions,carbon dioxide ions and hydrogen ions even some limestone also rises pH level and water becomes more basic.To make the tank water alkaline, add some corals and aerate the tank water by fixing an air pump so that excess of carbon dioxide eliminate out and water pH level comes to neutral this is the reason water becomes slightly alkaline and the fishes are able to reproduce.
The answer is D. Coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons which support and protect the coral polyps. Most reefs grow best in warm, shallow, clear, sunny and agitated water. @wiki Hope this helps and if your feeling generous give it a rate, thanks and brainliest because it would really help me get virtuoso and I would appreciate it ;)
Cell walls made of cellulose are present in plant cells. Human cells (skin, fingernails, muscle, etc.) do not have cell walls. Both plant and human fingernail cells have ribosomes and mitochondria. There are no cilia on either of the cells. Therefore, answer C is correct. Hope this helps! :)
