Guess it would be B. Is my answer
Answer:
Bilateral symmetry allows for directional motion. The coelom cushions organs allow freedom of motion.
Explanation:
Most animals are bilaterally symmetrical in nature with a line of symmetry dividing their body into two sides left and right sides along-with a “head” in top and “tail” in the bottom. Bilateral symmetry consisting an equal arrangement of symmetry about a vertical plane running from top to bottom.
The coelom is known as the main body cavity present in most animals. It is positioned inside the body to surrounds the digestive tract and other organs. In some animals, it is lined with mesothelium. In other animals, such as mollusks, it is undifferentiated. In animals, it helps to allow freedom of motion.
The answer is birth defect
Since there is no following to see what the options are I can only tell you that it will be a food web.
I hope this was helpful :)
The United Nations Conventions on the Law of the Sea (UNCLOS) declares that seabed area, which does not fall under the jurisdiction of a particular country, is a common natural heritage. The minerals of this area can be usd by anyone. Due to vast presence of sea area, and conflicting boundaries, as well as illegal mininig practices, the imposition of such laws is difficult. The very large sea areas which should not be mined, should be restrained under non mining region. But, mineral-greedy nations are not following such instructions.
The envrionmental implications of ilegal seabed mining includes, destabilisation of oceanic systems, effect on microbial systems of the sea, and danger to the creatures living in the hydrothermal vents, which are not used to light exposure.
