Frogs and earthworms breathe through their skin because of which the skin of both the organisms is

Options

A. dry and rough
B. dry and slimy
C. moist and rough
D. moist and slimy

Explanation

To determine the characteristics of the skin of frogs and earthworms, which breathe through their skin, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Skin Respiration**: Both frogs and earthworms use their skin for respiration. This process involves the absorption of oxygen directly from the environment through their skin.

2. **Identifying Skin Characteristics**: For skin to effectively absorb oxygen, it must have certain properties. The skin needs to be able to facilitate the diffusion of gases.

3. **Moisture Requirement**: The skin must be moist because oxygen from the air needs to dissolve in water before it can be absorbed by the skin cells. If the skin were dry, it would hinder the absorption of oxygen.

4. **Slimy Texture**: The skin of these organisms is also slimy. This sliminess is due to the secretion of mucus, which helps keep the skin moist and aids in the absorption process. The slimy texture allows for easier diffusion of gases.

5. **Conclusion**: Based on the above points, the skin of frogs and earthworms is best described as "moist and slimy." This characteristic allows them to efficiently absorb oxygen from their environment.

### Final Answer:
The skin of both frogs and earthworms is **moist and slimy**.
