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.
It’s just a black picture for me what is it
Answer:
True
Explanation:
<em>Research that seeks to understand the source of water pollution for given body of what is indeed an example of applied science.</em>
Applied science is a branch of science that deals with the application of scientific knowledge to solve real-life problems. This is as opposed to natural science which deals mainly with the physical world and is largely theoretical. <u>When the theoretical knowledge obtained from natural science is put to real use to solve existing problems, it is termed applied science. </u>
