Answer:
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.
The student put under the "physical changes" portion of the poster about aluminum is option "B".
<h3>What is the boiling point and melting point of aluminum?</h3>
The melting point of aluminum is 933.47 Kelvin, 660.32 degrees Celsius, or 1220.58 degrees Fahrenheit.
It's normal boiling point is 2792 Kelvin, 2579 degrees Celsius, or 4566 degrees Fahrenheit.
Thus, Options "B" aluminum met at 660 degree celcius.

<span>The choices can be found elsewhere and as follows:
</span><span>a)folded mountains
b)fault-block mountains
c)canyons
d)plateaus</span><span>
I think the correct answer is option B. Mountains that have developed because of compressional stress—colliding plates that force rock layers upward—are called </span>fault-block mountains.
Answer: A. cooled and hardened lava from volcanoes
C. sediments deposited by rivers and ocean currents
An accretion is a process in which new materials are added to a tectonic plate or landmass. This process causes the enlargement of the landmass. The materials being added includes sediments, lava from volcanic eruptions and other materials from other sources.
The process of accretion can enlarge the size of a continent along its edge. The new land comes from the cooled and hardened lava from volcanoes and other reason is sediments deposited by rivers and ocean currents.
I am not entirely sure, but i think it would be the respiratory system because plants produce oxygen after taking in carbon dioxide, and that is similar to the human respiratory system. I am not completely sure though. hope this helps!
