Cnidarians.
Explanation:
Cnidarians are known as the marine invertebrates, and also called as Coelenterata, they belong to phylum Cnidaria. Cnidarians include sea fans, sea pens, corals, hydra, jellyfish, and sea anemones. They belong to four classes: Anthozoa, Cubozoa, Hydrozoa, Scyphozoa.
Cnidarian captures its prey with the help of nematocysts which are thread-like tubes, coiled, and sticky. Nematocysts contain toxin by the release of this toxin corals hunt their prey, and even while they are stuck to the ocean floor.
Answer: Enzymes lower the activation energy found in food molecules
Explanation:
Food substances like yam, potatoes, egg etc are all made of chemical elements bounded to one another by chemical bonds such as hydrogen bonds, covalent bonds etc
During digestion, these bonds must be broken for carbohydrates to yield glucose, protein to yield amino acids.
Hence, added enzymes lowers the strength of this bonds i.e activation energy, by placing them into their active sites, which is equipped to cleave specific bonds
Thus, digestive reactions are quicker in the presence of enzymes than otherwise.

Explanation:h
Explanation:
Volume of a cylinder = 
r² h
Volume of a sphere = 
r³
Volume of cone = 
r² h
Volume of cuboid = l w h
Where:
r is the radius of the body measured
h is the height
l is the length
w is the width
The volume of a body is the space it occupies and it refers to its size.
it is measured in cubic meters or cubic centimeters.
