Answer: The most reasonable answer that is A. They serve as templates.
Explanation:

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.
Answer:
A. broad spectrum
Explanation:
An antibiotic is a substance that has the capability to inhibit the growth of or kill bacteria.
A broad spectrum antibiotic has the capability to be inhibit or kill a wide range of bacteria species while a narrow spectrum can only operate within a narrow range of bacteria species.
<em>Hence, in a situation where the the causative organism of the disease (the pathogen) is not known, it is better to use a broad spectrum antibiotic because such antibiotic has a higher chance of eliminating the pathogen.</em>
