Options

A. 5/6
B. 1/2
C. 3/10
D. 1/4

Answer

To solve the question about which part of the brain is connected with the sense of smell in sharks, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Anatomy of Sharks**:
- Sharks are a group of elasmobranch fishes characterized by a cartilaginous skeleton. They have distinct anatomical features, including gill slits and specialized nostrils.

2. **Identify the Function of Nostrils**:
- Sharks possess nostrils located on the underside of their snout. Unlike humans, these nostrils are primarily used for the sense of smell rather than for breathing.

3. **Recognize the Importance of Smell in Sharks**:
- Sharks are known for their acute sense of smell, which is crucial for hunting and navigation in their aquatic environment.

4. **Quantify the Brain's Involvement in Smell**:
- It has been noted that approximately 30% of a shark's brain is dedicated to processing olfactory (smell) information.

5. **Analyze the Options Given**:
- The options provided are:
- Option 1: 5 by 6
- Option 2: 1 by 2
- Option 3: 3 by 10
- Option 4: 1 by 4
- Since 30% can be expressed as a fraction, we can convert it to a fraction of 10, which is 3 out of 10 (3/10).

6. **Select the Correct Answer**:
- Based on the analysis, the correct answer is **Option 3: 3 by 10**, which corresponds to 30% of the brain being connected with the sense of smell in sharks.

### Final Answer:
The part of the brain connected with the sense of smell in sharks is **Option 3: 3 by 10**.
