- A. Pinworm
- B. Star fish
- C. Cake urchin
- D. Amphioxus
Explanation: Spiral and determinate type cleavage is present in proterostomes. Pinworm belongs to phylum. Aschelminthes that are proterostomes
Correct answer: Pinworm- A. Echinodermata
- B. Mollusca
- C. Chordata
- D. Hemichordata
Explanation: Molluscs are proterostomes and have determinate cleavage in which fate of blastomeres is foretold.
Correct answer: Mollusca- A. Bilaterally symmetrical
- B. Triploblastic metazoan
- C. Dorsoventrally compressel body
- D. Radially symmarical body
Explanation: Phylum Platyhelminthes have bilateral symmetry. This means there is only one plane of symmetry.
Correct answer: Radially symmarical body- A. Chitin
- B. Cuticle
- C. Cilia
- D. Spongin
Explanation: Intestinal parasites, generally do not absorb nutrients through the body surface as there is usually a thick cuticle to protect themselves…
Correct answer: Cuticle- A. Mouth
- B. Pharynx
- C. Laynx
- D. Anus
Explanation: The nematode nervous system consists of a set of neuronal processes that run lengthwise on the nematode body.
Correct answer: Pharynx- A. Setae, parapodia
- B. Parapodia, setae
- C. Setae
- D. Setae, chaetae
Explanation: Locomotary setae are for crawling and are the bristles that are visible on the exterior of the earthworm.
Correct answer: Parapodia, setae- A. Phylum Mollusca
- B. Phylum Porifera
- C. Phylum Annelida
- D. Phylum Arthropoda
Explanation: More than 50% of total biodiversity of our planet is formed by the Arthropods.
Correct answer: Phylum Arthropoda168. Natural silk is not:
- A. A protein
- B. Produced by modified salivary glands

- D. Glycolipid in nature
Explanation: Natural silk is fibrous protein produced by larvae of silk worm.
Correct answer: Glycolipid in nature- A. Muscle feet
- B. Jet propulsion

Explanation: Organs of locomotion in echinoderms are tube feet. These are present along the edges of grooves present in the arms.
Correct answer: Tube feet- A. Echinoderms
- B. Hemichordates
- C. Arthropods
- D. Chordates
Explanation: Arthropods are proterostomes in which cleavage is determinate (fate of blastomeres is foretold).
