Question

3. Which of the following statements are accurate?
A. Pseudocoelomates do not have a functioning internal body cavity between the digestive tract and body wall
B. A body cavity can cushion suspended organs.
C. A fluid or air-filled body cavity present in many triploblastic animals is also known as a coelom
D. A true coelom is formed from the mesoderm.
E. A body cavity prevents internal organs from growing and moving independently of one another

4. Which of the following statements are accurate?
A. All animals are prokaryotes
B. All animals are autotrophic eukaryotes
C. All animals have tissues
D. All animals have organs
E. All animals are multicellular.

5. Which of the following statements are accurate?
A. Bilaterians include three clades:
1. Deuterstomia
2. Protostomia
3. Ecdysozoa
B. Invertebrates are animals that lack a backbone
C. Lophotrochozoans, which includes molluscs and insects, typically have an exoskeleton that they can shed.
D. All animals except sponges share a common ancestor
E. Givens about animal "A"
I. the animal has three prominent germ layers
II. an animal has bilateral symmetry
III. the animal lacks a backbone
You would be only be able to classify this animal, animal A, as a lophotrochozoan

Answer 1

Question 4:

Answer: (E) All animals are multicellular

Explanation: All animals have more than one cells or multicellular and animal cells have defined nucleus enclosed within a membrane.

Prokaryotes do not have a defined nucleus so option (A) is not the correct answer.

Autotrophs are the ones which can synthesize it's own food. But animals are heterotrophs which depends on other organisms for their food. So option (B) is not the correct answer.

Some simpler animals like Trichoplax do not have organs and some simpler animals like porifera do not have true tissues. So option C and D cannot be the correct answer.
