Let's solve each question step by step and provide explanations for the answers.

Question 1: The damselfly life cycle is an example of...
-
Options:
- a- Complete metamorphosis
- b- Incomplete metamorphosis
Explanation:
-
Complete metamorphosis involves four stages: egg, larva, pupa, and adult. Examples include butterflies and beetles.
-
Incomplete metamorphosis involves three stages: egg, nymph, and adult. Examples include grasshoppers, crickets, and damselflies.
- Damselflies undergo incomplete metamorphosis, where the young (nymphs) resemble the adults but are smaller and lack wings.
Answer:
b- Incomplete metamorphosis

Question 2: The butterfly life cycle is an example of...
-
Options:
- a- Complete metamorphosis
- b- Incomplete metamorphosis
Explanation:
- Butterflies undergo complete metamorphosis, which includes four distinct stages: egg, larva (caterpillar), pupa (chrysalis), and adult (butterfly).
Answer:
a- Complete metamorphosis
---
Question 3: Egg, nymph, molting, and adult are the stages of...
-
Options:
- a- Any metamorphosis
- b- Complete metamorphosis
- c- Incomplete metamorphosis
Explanation:
- The terms "egg," "nymph," and "adult" are characteristic of
incomplete metamorphosis. During this process:
- The
nymph stage resembles the adult but is smaller and lacks fully developed wings.
- The nymph undergoes multiple molts (shedding its exoskeleton) as it grows.
- Complete metamorphosis does not involve a nymph stage; instead, it has a larva and pupa stage.
Answer:
c- Incomplete metamorphosis

Question 4: Egg, larva, pupa, and adult are the stages of...
-
Options:
- a- Any metamorphosis
- b- Complete metamorphosis
- c- Incomplete metamorphosis
Explanation:
- The stages "egg, larva, pupa, and adult" are characteristic of
complete metamorphosis. During this process:
- The
larva (e.g., caterpillar in butterflies) is significantly different from the adult.
- The
pupa (e.g., chrysalis in butterflies) is a non-feeding stage where transformation occurs.
- The adult emerges from the pupa.
Answer:
b- Complete metamorphosis
---
Question 5: He __________ is a wormlike animal that eats leaves.
-
Options:
- a- pupa
- b- adult
- c- larva
Explanation:
- In the context of insects, the
larva is typically wormlike and feeds voraciously to grow. For example, the larva of a butterfly (caterpillar) is wormlike and eats leaves.
- The
pupa is a non-feeding stage where transformation occurs, and the
adult is the fully developed insect.
Answer:
c- larva
---
Question 6: The __________ is the young damselfly.
-
Options:
- a- nymph
- b- adult
- c- larva
Explanation:
- The young stage of a damselfly is called a
nymph. Nymphs are aquatic and undergo incomplete metamorphosis, eventually emerging as adults.
- The term "larva" is used for organisms with complete metamorphosis (e.g., butterflies), and "adult" refers to the fully grown form.
Answer:
a- nymph
