Question

Select each statement that is true about Dermal Denticles (select all that apply) abnormalities on the skin improve hydrodynamic efficiency sensory pits that detect vibrations increase drag provide protection are modified teeth covered with hard enamel

Answer 1

The correct statements about dermal denticles are:- **Improve hydrodynamic efficiency** - **Provide protection** - **Are modified teeth covered with hard enamel**### Explanation:1. **Improve hydrodynamic efficiency**: Dermal denticles reduce drag and turbulence in water, allowing sharks and other cartilaginous fish to swim more efficiently.2. **Provide protection**: The tough, tooth-like structure of dermal denticles helps protect the skin from predators, parasites, and physical damage.3. **Are modified teeth covered with hard enamel**: Dermal denticles are structurally similar to teeth, as they are made of dentin and covered with a hard enamel-like substance.The other options are incorrect because:- **Abnormalities on the skin**: Dermal denticles are not abnormalities; they are a normal feature of cartilaginous fish like sharks and rays.- **Sensory pits that detect vibrations**: This describes the lateral line system, not dermal denticles.- **Increase drag**: Dermal denticles actually reduce drag, not increase it.
