The avian
kidneys are divided into units called lobules and as the two avian kidneys of
birds do their work or function, most of these birds excrete nitrogenous waste
known as uric acid from the blood, which reduces water loss but requires more
metabolic energy to produce nitrogenous waste.

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.

Depending on the institution, substance-abuse treatments may vary in regard to duration and phases. Generally, treatments for substance abuse consist of four phases:

- Abstinence - first phase: This stage is one of the most difficult ones as the person usually exhibits a variety of emotions associated with depression, sadness, anxiety because of the withdrawal of the drug. <u>During this phase, they received psychological help to prevent any relapse and to </u><u>become more stable</u><u>, that is, to </u><u>control drug cravings.</u>
- Abstinence - second phase: This stage is focused on<u> maintaining abstinence and stability</u>. In conjunction with the second phase, this is also difficult but rewarding. The person receives behavioral therapy so he/she can acknowledge how the drug intake resulted in numerous issues and, in contrast, stopping its use can change her/his life in a diversity of positive ways.
- Aftercare: This stage focuses on long-term goals and, through therapy and counselling, <u>helps the person to </u><u>obtain education, find a job</u><u>, and </u><u>continue their stability and abstinence.</u>
