What Is Anthozoans?

The American colonists were justified in waging war and breaking away from Britain. In fact, they had every right to fight against the British. They were justified because of unjust laws and a parliament of tyranny.

Five negative developments have occurred since the removal of prayer from public school. Academic achievement has plunged (including SAT scores). There has been an increased rate of out-of-wedlock births, leaving single mothers to struggle to survive (Starr, 2014). Illegal drug use has gone rampant. The amount of juvenile crime has skyrocketed. Lastly, behavior in school has drastically deteriorated. William Jeynes, a professor at California State College, says “ so we need to realize that these actions do have consequences” (Starr, 2014). These negative developments have occurred since the Engle v. Vitale case of 1962.

In conclusion, coral is a single; it’s made up of thousands of ploys. Which secrete the limestones that attaches to rock or ocean bed and keeps them in the places where they came. That’s why if we stop the main cause of this--fishermen-- we’ll be able to see the coral reefs. The central idea of the article, “ Ingenious Coralbots May Help Restore Coral Reefs”, is that humans should stop taking the coral reefs from their

A coral structure is actually made up of hundreds - thousands of tiny little animals all growing together as a colony. These polyps are the makers of the coral reef and have accumulated over thousands of years to make up the largest living structures in the world. The anemones, which go along with the corals, are typically partnered with clownfish. In this relationship both animals work together in order to benefit each other. The anemone will provide protection for the clownfish, while the clownfish provides food for the anemone (seasky).

Coral reefs exist all over the world and are generally known as being one of the most diverse, intricate and beautiful of all existing marine habitats. They have many varying structures which are developed by algae and are symbiotic with various reef building corals which are referred to as, zooxanthellae (algae). There are many other factors such as, coralline algae, sponges and other various organisms that are combined with a number of cementation processes which also contribute to reef growth, (CORAL REEFS, 2015).

Coral reefs are wonderful places in the ocean they can be found in shallow water where it is warm and unpolluted. Funny thing is even though they look like plants they are living organisms. There are many kinds like lettuce coral, fire coral, and leather coral. There is also a lot of sea life like cuttlefish, manta ray, and reef whitetip shark. Speaking of sharks, the coral reef is also where many sharks feed.

One of the most diverse and biologically rich marine ecosystems is the coral reef. Almost every ecosystem has a greater purpose, coral reef are no exception. For instance they serve as barriers for hurricanes, and other catastrophic storms, their chemicals treat diseases, and one of the most important function is they are a major source of food for humans. But that is just the benefits for humans, they provide shelter and food for numerous organisms, such as fish, turtles, dolphins, and several other marine life.

Coral reefs are the most biodiverse ecosystem on the planet. There are more than 25,000 known species of organisms and countless others that have yet to be identified (Helvarg, 2000). Reefs thrive on the shallow edge of tropical seas, most often on the eastern edge of continents along warm water currents that brush the coasts. Reefs cannot live in cold waters and are limited by ocean depth and available sunlight. Coral is the foundation of the reef community, providing a three-dimensional structure where thousands of species of vertebrates and invertebrates live and feed. Some species of coral are hard, while others soft. Some are branched, yet others are compact and rounded. Coral is made up of large

China’s one-child policy was implemented in 1979 by Deng Xiaoping to limit China’s population growth, under the belief that overpopulation would inhibit its economic growth (History of the One-Child Policy). The policy restricted couples to only have one child, unless they were of an ethnic minority (Pong, 168). It was later amended in 2002 to include allowing two only-child parents to have two children, and allowed rural families to have another child if the first was a daughter (China’s One-Child Policy). On October 25, 2015, the Chinese government repealed the one-child policy in favor of a two-child policy because of the massive gender imbalance that it had caused (Taylor). Principally led by the much reviled establishment of the one-child policy, China’s abundance of males compared to females dramatically altered the demographics of the country, leaving millions of men unable to have a family, damaging the traditional cultural aspect of the Chinese family (Brooks). The disproportion originated from a traditionally boy-favoring Chinese culture and the future economic support a boy promised, while widespread use of ultrasound technology caused a decrease in births of girls (Brooks). Although successful in its goals of limiting population growth, the one-child policy, because of the Chinese cultural and economic support boys provided, had the unintended consequence of creating a gender imbalance, resulting in

Corals are proven to cure serious illnesses such as cancers and heart diseases. By providing this information to tourists they will be more careful and respectful to the life saving coral reefs. This will impact us, our community, and almost everybody's family along with people who has been diagnosed with cancer or has cancer. We hope that you think about our surrounding

First, I am going to talk about the importance of coral reefs. Coral reefs are some of the most diverse and valuable ecosystems on Earth. They are home to 4,000 species of fish, 800 species of hard coral, and hundreds of other species. Scientists believe that there are another 1 to 8 million unidentified species (NOAA). According to the National Oceanic and Atmospheric Administration, new drugs are being developed from

They protect against coastal flooding, wave damage, storm surges, wave damage, and also they provide homes for lots of fish.. Coral reefs are dying because of the increase in ocean acidification that is caused by the increase of CO2 in the atmosphere. Coral reefs may stop growing if the CO2 concentration levels are high which is expected over the coming decades according to the article. Coral reefs are also vital for people and business. In the article it was reported that more than 30 million small-scale fisherman and women depend on coral reefs for their livelihoods, specifically in Indonesia where fish supported by the reefs provide the primary source of protein.

Consisting of less than 1% of the world oceans, the coral reefs are ancient animals comprising of thin calcium carbonate deposits within the photic layer. Aside from its biologically diverse ecosystems, coral reefs are major source of food for millions and provides habitats and nursery areas for many marine organisms. Coral reefs also act as a physical buffer to protect the coastlines from tropical storms and erosion. In addition, many local communities rely on coral reefs to generate an income through activities such as fishing and diving. However, 75% of the coral reefs are under threat from induced impacts of humans and climate change (Burke, et al., 2011). This essay looks at the human impacts constantly being inflicted on coral reefs.

     Coral reefs are one of the oldest types of living systems on earth, and certainly one of the most spectacular (Goreau, 1987). They are massive underwater structures formed by the limestone skeletons of tiny invertebrate animals. Reefs house a greater diversity of body forms, chemistry, and animal phyla (thirty-two compared to the eight that inhabit the most biodiversity ecosystems on land). Phyla comprise the second largest category of living things, after kingdoms.

Polyps are the individual animals that make up the coral colony. They are essentially a round animal with a mouth in the middle and a ring of tentacles around the mouth. The tentacles possess stinging cells (called nematocysts) and can be used to sting, paralyze, and catch prey. They also share a communal skeleton that is made up of calcium carbonate (CaCO3). The calcium carbonate is collected from the water column, and in a closed system (like a fish tank) this must be dosed daily. Proper levels of calcium and alkalinity are essential for overall health of the reef.
