Let's solve this step-by-step.

Step 1: Identify the animals in the images

We have five reptiles shown:

1. Iguana – a large lizard with a long tail and spiny back.
2. Crocodile – a large aquatic reptile with a broad snout and strong jaws.
3. Gecko – a small lizard with distinctive eyes and often adhesive toe pads (the one shown is likely a leopard gecko).
4. Tortoise – a land turtle with a heavy, dome-shaped shell.
5. Sea Turtle – a marine turtle with flippers for swimming.

So, label each box under the images:
- First row:
- Iguana → Iguana
- Crocodile → Crocodile
- Gecko → Gecko
- Second row:
- Tortoise → Tortoise
- Sea Turtle → Sea Turtle

Step 2: Answer the fill-in-the-blank questions

Now, let’s go through each question and provide the correct answer based on reptile biology.

---

#### 1. Reptiles lay their eggs on _________________.

✔ Land
Most reptiles are oviparous (lay eggs), and they typically lay their eggs on land, often in burrows or nests to protect them from water and predators.

> ✔ Answer: land

---

#### 2. All reptiles use _________________ to breathe.

✔ Lungs
All reptiles are air-breathing vertebrates and use lungs to breathe, even if they live in water (like turtles and crocodiles).

> ✔ Answer: lungs

---

#### 3. Reptiles have _________________, scaly and rough skin.

✔ Dry
Reptile skin is dry, covered in scales, which helps prevent water loss and protects them.

> ✔ Answer: dry

---

#### 4. Lizards, _________________, Turtles, Alligators and Crocodiles are reptile.

This is asking for another example of a reptile that fits in the list.

The missing one is snakes — they are closely related to lizards and are also reptiles.

> ✔ Answer: snakes

(Other possible answers could be "geckos", "iguanas", etc., but "snakes" is the most common and fitting blank here.)

---

#### 5. Reptiles are _________________ and cold-blooded animals.

✔ Ectothermic
"Cold-blooded" means their body temperature depends on the environment. The scientific term is ectothermic.

> ✔ Answer: ectothermic

---

#### 6. A reptile that can blend with their surrounding is _________________.

This refers to camouflage. Among the listed animals, geckos and iguanas can blend in well due to coloration and patterns.

But the leopard gecko shown has spots that help it blend into rocky or sandy environments.

Alternatively, chameleons are famous for camouflage, but not pictured.

Since the image includes a gecko, and geckos are known for blending in, the best answer is:

> ✔ Answer: gecko

Or more specifically: leopard gecko — but since it's just labeled as "gecko" in the image, gecko is acceptable.

---

✔ Final Answers:

#### Labels under images:
1. Iguana
2. Crocodile
3. Gecko
4. Tortoise
5. Sea Turtle

#### Fill-in-the-blanks:
1. Reptiles lay their eggs on land.
2. All reptiles use lungs to breathe.
3. Reptiles have dry, scaly and rough skin.
4. Lizards, snakes, Turtles, Alligators and Crocodiles are reptiles.
5. Reptiles are ectothermic and cold-blooded animals.
6. A reptile that can blend with their surrounding is gecko.
