Question

question 5 (2.5 points)
a mite is most closely related to which of the following?
ants
spiders
isopods
leeches
flukes
question 6 (2.5 points)
which animal lacks symmetry, has no embryonic tissues, and has intracellular digestion?
a cnidarian
a flatworm

Explanation:

• Question 5: Mites are arachnids. Spiders are also arachnids. Ants are insects (class Insecta), isopods are crustaceans (class Malacostraca), leeches are annelids (class Clitellata), and flukes are platyhelminthes (class Trematoda). Arachnids share a more recent common ancestor with each other than with members of other classes.
• Question 6: Sponges (phylum Porifera) lack symmetry (are asymmetrical in many cases), have no true embryonic tissues (they have cell - types but not the three germ layers like eumetazoans), and have intracellular digestion. Cnidarians (e.g., jellyfish) have radial symmetry and extracellular digestion in their gastrovascular cavity. Flatworms (phylum Platyhelminthes) have bilateral symmetry.

Answer:

• Question 5: spiders
• Question 6: (Since the options provided for question 6 do not include sponge, but if we assume it's a mis - optioning and based on the characteristics: lack of symmetry, no embryonic tissues, intracellular digestion, the closest in the given options is not correct. But if we follow the knowledge, the correct group is sponges. However, if we consider the options strictly, there is an error in the question's options. But if we have to choose from the given options for question 6, neither a cnidarian nor a flatworm meets all the criteria. But if we assume it's a wrong - option - set and based on the characteristics, the answer should be a sponge (not in options). But if we follow the options as they are, there is no correct answer. But if we consider the knowledge for question 5: spiders)
