Rocks,water,pebbles = Abiotic
Fish =Biotic
Answer:
These structures that protect the sponges from most predators, but not turtles, are spicules.
Explanation:
Sponges <em>skeleton</em> is composed of <em>calcium carbonate and siliceous</em> micro-structures called <u>spicules</u>. Their morphology is so varied that it is used in taxonomy for identification and classification.
There are different kinds of spicules:
- <em>Monoaxonic spicule</em>: needle-shaped, straights or curves
- <em>Tetraxonic spicules:</em> they have four prolongations
- <em>Triaxonic or Hexaxonic spicules</em>
- <em>Poliaxonic spicules </em>
Two terms can be applied to any of these spicules kinds:
- <em>Megaspicules</em>: They are elongated and compose the main architecture of the sponge skeleton
- <em>Microspicules</em>: Variable in shape and size, with ancillary functions
Sponges have few predators thank to the spicule structures and their high toxicity. Many of them are capable of perforating soft tissues and producing urticant substances.
The hydrolysis of triglycerides on a spirit blue agar plate most closely resembles that of beta hemolysis on a blood agar plate.
The hydrolysis of triglycerides on a spirit blue agar plate is used for identifying bacteria based on what organic compounds they can break down, in this case lipids. Spirit blue agar is a medium that contains a supply of lipids. If bacteria have lipase, the enzyme capable of breaking down lipids spirit blue agar will be digested and it will appear as a halos around colonies of bacteria that make lipase.
The ability of bacterial colonies to induce hemolysis (the breakage of red blood cells) when grown on blood agar is used to identify microorganisms. Beta hemolysis is a complete lysis of red blood cells and in the blood agar, that area under the colonies that do the hemolysis appears lightened and transparent.
