The given statement is True.
Sea corals are found deep inside the sea and oceans. They can survive in the shallow water. Deep sea corals can be found in groups or else can be found individually in water. They belong to phylum cnidaria and they live for thousands of years. They are found deep inside and if not disturbed in their habitat they can live long.
Meiosis.
Meiosis results in four cells of the original, each with a halved amount of chromosomes, you could say.
"The frog's back legs are what do most of the work during jumping and landing. A frog's front legs are his shock absorbers when he lands a jump.Aquatic and semi-aquatic frogs live most of their lives in the water or near it. Swimming is an essential skill and leaping is mostly done on level surfaces or for dives. Because the frog's habitat relies on these kinds of movement, the back legs have developed to be much larger than the front legs. <span>Some frogs live in environments where the front legs are just as important as the back legs and are about equal in size. Tree frogs use their front legs heavily. If you watch a tree frog leaping through branches, you can see him reach out to his target with his front legs and feet to take hold of a surface, then draw his back legs onto it. In the case of tree frogs the front and back legs split the work of locomotion almost equally." (animals.pawnation.com).</span>
Eutrophication is the input of excessive nutrients into fresh surface waters. Nutrients can cause algal blooms. Some of these algae can be toxic, and algal death can also result in anoxic conditions, leading to fish deaths. Some indicators of eutrophic conditions can be high measures of important nutrients such as phosphates and nitrates. Another indication of eutrophication can be high concentrations of algal cells. Finally, low dissolved oxygen can indicate eutrophic conditions.
