Answer:
Explanation:
a. Flame cells: In the certain freshwater invertebrates such as rotifers some flatworms, there is presence of special excretory. A flame cell works as a kidney that removes waste materials.
b. Ocelli: These are the organs present in most of the arthropods. These are light detecting organs consists of a single lens and several sensory cells which detect movements.
c. Toxicyst: It is a specialized cellular structure present in some protozoa which are used to capture prey.
d. Nematocyst: It is small elongated capsule present in the members such as Hydra, jellyfish, sea anemones of phylum Cnidaria. Each nematocyst has a coiled, hollow, usually barbed thread. The thread contains poison and used to kill prey.
e. Colloblasts are a cell present in the tentacles of the ctenophores of the phylum Cnidaria. It has of a coiled spiral filament which are used to capture prey.

Continental crust is defined as having higher concentrations of very light elements like K, Na, and Ca, and is the lowest density rocky layer of Earth. Its average composition is similar to granite.
The crust, with an average density of around 2.6 grams per cubic centimeter (g/cm3), is less dense than the mantle (average density of approximately 3.4 g/cm3 near the surface, but more than that at depth), and so it is floating on the “plastic” mantle. Earth's interior layers are ordered by density. The densest layer is the solid metal inner core, the mantle is of intermediate density, and the least dense layer is the lithosphere, particularly the continental lithosphere Earth's Crust. “Crust” describes the outermost shell of a terrestrial planet. Earth's crust is generally divided into older, thicker continental crust and younger, denser oceanic crust
