Answer:
B. Ecdysozoa.
Explanation:
Ecdysozoa is the large group of animals that undergo the process of ecdysis which can regularly shed their outer skin made of the cuticle. This process of shedding the outer skin is also known as molting which is observed in the species of the nematodes and the arthropods.
In the given question, since the new species shed their outer skin which is a characteristic feature of the Ecdysozoa, therefore, the new animal species belongs to the Ecdysozoa.
Thus, Option-B is the correct answer.
The statement that correctly compares synthesis and decomposition reactions would be that <u>synthesis and decomposition reactions are opposites of each other. Synthesis reactions are in the form A + B → AB, while decomposition reactions are in the form AB → A + B.</u> Thus, A would be the right option.
In synthesis reactions, two different atoms combine to form a compound, such that:
A + B ---> AB...................equation 1
In decomposition reactions, a compound or molecule disintegrates to form two different atoms or molecules, such that:
AB ---> A + B......................equation 2
Equation 1 is essentially the opposite of equation 2. Thus, it can be said that synthesis and decomposition reactions are opposites of each other.

<span>well first off you should read the manual and then be careful not to break it
Use tongs to grab your test tubes at the center. Wrap the tongs around the center, and hold firmly but not too tightly.
Keep the test tube angled away from you at all times, in case of any splashing.
When warming the test tube, hold it over the flame at an angle, moving it back and forth gently.
4
Never smell anything inside a test tube directly or look inside a test tube. Waft the air or fumes emitted from the test tube away from you.
5
When not using a test tube, place it upright in the test tube holder. This will help prevent spillage or accidents. hope this helped out.</span>
