The correct answers are:
Trematodes are acoelomates that have effective defenses against attack by their hosts' immune system.
Trematodes are flatworms, internal parasites known as flukes. Their life cycle is complex: they sexually reproduce in vertebrates and asexual reproduce in mollusks (mostly snail). The body of flukes is covered with tough tegument that defends them form digestive enzymes of host’s intestine.
Cnidarians are diploblasts that produce complex, capsule-like organelles.
Cnidaria are water organisms with simple structure: two layers of epithelium and a jelly substance between them. The cells of Cnidaria-cnidocytes contain capsule with venom substance in it with protective role.

Answer:
it's called taxonomy or binomial nomenclature
the first name is generic (from genus) and begins with a capital letter
the second name is specific (from species) and begins with a small letter
Answer:
birth rate and death rate
An adaptation occurs when a species is set through a new constraint. This can be change in climate, defense mechanisms, food source, etc. Which will have to occur before an adaptation is made. For an example: in North America the climate slightly swifted. This meant smaller mammals such as rabbits would need to have a thicker coat of fur or shelter. Let's say all the thin furred rabbits died and all that remained were the thick furred rabbits. Over a span of time the rabbits have adapted through the climate. Meaning most of the population is thick furred through their DNA. Conclusively, it's a genetic characteristic that can happen very rapidly or slowly.
I hope this solved your question!
