The correct Answer is:
To answer the question regarding Mud Eel (Siren lacertina) and its gill structure, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Organism**: The organism in question is the Mud Eel, scientifically known as Siren lacertina. It is important to understand its classification and characteristics. 2. **Class and Order**: The Mud Eel belongs to the class Amphibia and the order Sireniformes. Amphibians are known for their dual life, living both in water and on land. 3. **Physical Characteristics**: Mud Eels are eel-like in form and possess two small but fully developed forelimbs. Notably, they lack hindlimbs. 4. **Gill Structure**: The question specifically asks about the gill structure of the Mud Eel. It is important to differentiate between external gills and gill slits. 5. **Number of Gill Pairs**: Upon examining the Mud Eel, it is established that it has three pairs of both external gills and gill slits. 6. **Choosing the Correct Option**: Given the options provided: - Option 1: Five pairs of both external gill slits and gill slits - Option 2: Four pairs of both external gills and gill slits - Option 3: Three pairs each of external gills and gill slits (Correct Answer) - Option 4: Two pairs each of external gills and gill slits The correct option is **Option 3**, which states that Mud Eel has three pairs each of external gills and gill slits. 7. **Conclusion**: Therefore, the Mud Eel (Siren lacertina) has three pairs each of external gills and gill slits.

A person is riding a motorcycle at a speed v towards a stationary car operating its siren at 165Hz. A police car is chasing the person at a speed 22 m/s with its siren operating at 176 Hz. If the motorcyclist does not heard beats, the speed v (m/s) is (speed of sound in air = 330 m/s)

A police siren emits a sinusoidal wave with frequency f_(S) = 300 H_(z) . The speed of the sound is 340 m//s . (a) Find the wavelength of the waves if siren is at rest in the air . (b) If the siren is moving at 30 m//s , Find the wavelength of the waves ahead of and behind the source.

A siren creates a sound level of 60 dB at a location 500 m from the speaker. The siren is powered by a batter that delivers a total energy of 1.0 kJ . Assuming that the efficiency of siren is 30% , determine the total time the siren can sound.

A listener is at rest and a police siren is moving away from the listerner at 60m/s. what frequency does the listerner hear given that the velocity of sound in air is 340m/s and frequency os siren is 500Hz?

Suppose you set your watch by the sound of a distance siren, will it go fast or slow?
