Step 1: Identify the animals in the images

From left to right, top to bottom:

1. Iguana – a type of lizard
2. Crocodile – a large reptile with a long snout and armored skin
3. Gecko – a small lizard with sticky toes (often nocturnal)
4. Tortoise – a land turtle with a heavy shell
5. Sea Turtle – a marine turtle that lives in oceans

So, we can label them as:
- Iguana
- Crocodile
- Gecko
- Tortoise
- Sea Turtle

Step 2: Fill in the blanks in the questions

Let’s go through each question one by one.

---

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

✔ Answer: *Land*
Reptiles are oviparous (egg-laying), and they typically lay their eggs on land, often in sand or soil, to protect them from water and predators.

---

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

✔ Answer: *Lungs*
All reptiles breathe using lungs. They do not have gills like fish. Even aquatic reptiles (like turtles and crocodiles) must come to the surface to breathe air.

---

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

✔ Answer: *Dry*
Reptiles have dry, scaly skin that helps prevent water loss. This is an adaptation for life on land.

---

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

✔ Answer: *Snakes*
The main groups of reptiles include lizards, snakes, turtles, crocodilians (alligators and crocodiles), and tuataras. So "snakes" fits perfectly here.

---

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

✔ Answer: *Ectothermic*
"Cold-blooded" means they rely on external sources of heat to regulate body temperature. The scientific term is ectothermic.

(Alternatively, if the expected answer is simpler, it might be just "cold-blooded", but since the blank is after "are", it's likely expecting "ectothermic".)

But since the sentence already says "cold-blooded", perhaps the blank is meant to be filled with another trait. Let's re-read:

> Reptiles are _________________ and cold-blooded animals.

This suggests two traits. But "cold-blooded" is already stated, so maybe the first part is about vertebrates?

Wait — actually, let's think again.

Commonly, reptiles are described as:
- Vertebrates
- Ectothermic (cold-blooded)
- Lay eggs (oviparous or ovoviviparous)
- Have scales

So the best fit for the blank might be vertebrates, because all reptiles are vertebrates.

✔ Answer: *Vertebrates*

So: "Reptiles are vertebrates and cold-blooded animals."

Yes, that makes sense.

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

✔ Answer: *Chameleon* or *Gecko*
Looking at the images, the gecko has a spotted pattern that helps it camouflage. Also, chameleons are famous for changing color to blend in.

But the image shows a gecko, which is known for its ability to blend into surroundings.

Also, many geckos have cryptic coloration.

✔ So, gecko is a good answer.

Alternatively, if you're thinking of color-changing, chameleon is more accurate, but it's not shown.

Since the gecko is shown and it camouflages well, the answer should be:

✔ Gecko

1. Iguana
2. Crocodile
3. Gecko
4. Tortoise
5. Sea Turtle
