Question

Which of the feature is not present in amphibia? M) Scales are present (2) Most of them have two pairs of limbs for locomotion (3)Eyes have eyelids (4)Organisms are cold-blooded

Answer 1

Answer: Option 1) Scales are present.

Explanation: Amphibia have most skin with no scales on them.

Answer 2

Answer:

The odd one out is Option (1) : Scales are present.

Explanation:

Amphibians are tiny animals that cannot exist without water or a damp environment. Through their extremely thin skin, they can all breathe and absorb water. Amphibians have specific skin glands that create proteins that are crucial to them.

Examples of amphibians : Frogs, toads, salamanders, and newts are all members of this group.

Explanation of all the options :

1. While many amphibians have smooth skin, such as frogs, salamanders, and caecilians, most toads have rough bodies with elevated glands, some of which generate toxic secretions. Amphibians, on the other hand, do not have scales.
2. For locomotion, most of the amphibians have two sets of limbs.
3. They, like other species with eyes, require protection since their eyes are a vital sensory organ for many species, allowing prey to avoid predators and predators to find prey.
4. Herpetofauna, or "herps" for short, includes amphibians and reptiles. Herps are all cold-blooded, which means they don't have an internal thermostat. Instead, they must control their body temperatures by interacting with their surroundings.

Hence Option (1) is the odd one out among these.
