This is the basal disc. It is useful in helping the hydrozoans stick to and stay on the rocks around them.
Metamophic Rock :)
Rocks are made up of minerals. There are more types of rocks because rocks can be classified based on how they are formed, such as igneous, sedimentary, and metamorphic rocks. Minerals, on the other hand, are defined by their chemical composition and crystal structure, so there are fewer categories compared to rocks.
Yes, barnacles are living organisms. They are arthropods that attach themselves to hard surfaces like rocks or the hulls of ships, using a cement-like substance. They feed by filtering small particles from the water using their feathery legs.
Yes, barnacles are living organisms. They are marine crustaceans that attach themselves to hard surfaces such as rocks, boat hulls, or even whales, using a cement-like substance. They filter feed on plankton and other food particles in the water to survive.
the dead log is made up of cell.but the rocks are not made up of cell.
Rocks, and the skeletons of dead corals.
Sea creatures that attach themselves to rocks include shellfish such as limpets, mussels, oysters, barnacles.
Barnacles attach themselves to rocks at the shore by secreting a strong adhesive that allows them to firmly grip onto the surface. This allows them to filter food particles from the surrounding water while remaining protected from predators.
Hydras attach themselves using a sticky substance secreted by special adhesive cells called basal discs at the base of their tentacles. This allows them to anchor to surfaces in their aquatic habitat, such as rocks or water plants, while they feed and interact with their environment.
In a rockpool on the seashore, they attach to rocks
By scraping against them.
Mussels attach themselves to rocks and other structures on ocean and lake floors with byssal threads. These strong threads, sometimes called beards, are emitted as a liquid that hardens in the water. Source: http://www.ehow.com/facts_4925405_mussel-facts.html
Nonvascular plants, for instance, the mosses, have root-like structures called rhizoids used to attach themselves to soil, trees, rocks and other structures.
In intertidal zones, space on rocks is often competed for by various organisms such as barnacles, mussels, limpets, and algae. These organisms attach themselves to the rocks and compete for space to maximize their access to sunlight, nutrients, and water. This competition can influence the distribution and abundance of species in the intertidal habitat.
rocks that do not have a layered structure.
No
In some cases the molten rock cools too quickly for the atoms to arrange themselves into a crystalline structure.
