Which thing is also called black gold?
Oil is also known as black gold because of its high value and importance in the global economy.
Which oxide of nitrogen is also called as mixed anhydride?
Nitrogen Dioxide-NO2 is also called as mixed anhydride.
What is methane also known as?
Methane is called a marsh gas because it is formed by methanogenic organisms that can be found is marshes (thus concentrations can be found in marches).
Why petroleum is called black gold or crude oil?
Petroleum is called "black gold" because of its value, versatility, and economic significance, similar to that of gold. It is also referred to as "crude oil" because it is a natural, unrefined oil extracted from the earth, before being processed into various petroleum products.

What kind of organisms are the coral?
calcified rocks \
Are coelenterates unicellular?
No, coelenterates, also known as cnidarians, are not unicellular; they are multicellular organisms. This group includes animals such as jellyfish, corals, and sea anemones, which have specialized cells and tissues. While they may have simple body structures, they are composed of multiple cell types that perform different functions.
What are coelentrates?
Cnidarians, also known as coelenterates, are a phylum of animals that includes jellyfish, corals, and sea anemones. They are characterized by possessing specialized stinging cells called cnidocytes used for capturing prey and defense. Cnidarians have radial symmetry and a simple body plan with a central mouth surrounded by tentacles.
What is the cnidarians string cells?
They are called pneumatocysts. They are the stinging cells used for killing prey, as all cnidarians are predators. They are cells that contain poison, and have little barbs on them to inject the poison with. With some cnidarians, the little barbs are all that you feel because their poison is only strong enough to kill plankton. With other cnidarians, however, the poison in the pneumatocysts is strong and can be deadly. The main purpose of the pneumatocysts is to kill prey, but they are also useful against predators.
What are the few organs that Cnidarians have?
Cnidarians have a simple body plan with a sac-like structure composed of three layers of cells: the epidermis, the gastrodermis, and the mesoglea. They possess specialized cells called cnidocytes that contain stinging structures called nematocysts, used for defense and capturing prey. Cnidarians also have a simple nerve net for coordinating movements and responses.
Why are coelenterates more advanced than sponges?
sponges are made up of individual cells. I dont know about colentrates. They just are what they are. sponges also don't move while coelenterates do.
How do ctenophores differ from cnidarians?
Ctenophores are gelatinous creatures with rows of cilia for movement and lack stinging cells, while cnidarians have stinging cells called cnidocytes. Ctenophores also have a simpler body structure compared to the more complex body plans of cnidarians, which include jellyfish, corals, and sea anemones.
What is an example of cnidarians?
Cnidarians are the group of invertebrate animals which possess stinging cells called cnidocytes. The popularly-known cnidarians fall into only a couple of major groups. The Anthozoans or corals, sea pens, and anemones are sessile--that is stationary in lifestyle. The Scyphozoa or jellyfish are motile (mobile in lifestyle). So, the answer to the question is that anemones, coral, and jellyfish are all cnidarians.
Why soft animals like cnidarians don't live on land?
Cnidarians and sponges receive most of their food from filtering water; they would starve without water. Also, they would most likely crush themselves because of their body weight if they were on land.
How do coelentrate move?
Coelenterates move freely swimming in the water. While some coelenterates are sedentary. For exmple Hydra shows different modes of locomotion like looping, somersaulting, gliding etc. In Aurelia (moon jelly), medusa stages move freely swimming in the water.
What animals belong to the cnidarians group?
It is called a polyp. Some examples are sea anemones and hydras.
Is the coral reef built by mollusks?
No, coral reefs are cnidarians. The reefs themselves are built by coral polyps. Coral reefs are considered cnidarians along with what you and I would commonly refer to as jellyfish. Sea anemones are also cnidarians.
