Frogdissectionpre Lab

The document provides instructions and questions for a frog dissection pre-lab. It includes taxonomy information about frogs, as well as external and internal anatomy questions. The questions cover frog adaptations, differences between tadpoles and frogs, anatomical terms like dorsal and ventral, and reasons for certain anatomical features like lung development and tongue orientation. The final part provides a diagram to label internal organs for the upcoming dissection.

3. SubPhylum ___________Vertabrata___________________

5. Whyare frogs said to have two lives?


Because they live in water until they are fully grown. When they are grown they live on
land.

6. How are amphibians different from reptiles?


Reptiles have different skin they have gills, scales, and claws on toes. amphibians live on
land and water.
7. What are 3 adaptations that frogs have that make them amphibians?
1. Cold blooded 2. 3 chambered heart. 3. They respire by skin and lungs
8. List two ways in which tadpoles (immature frogs) and frogs differ from each other?
Tadpoles have gills to breathe underwater. Frogs have lungs to breathe above water.

External Anatomy
9. Dorsal means? Upper side or back of organ or animal.

10. V
entral means? Underside of animal

11. A
nterior means? Front of the body or near the head.

14. T
orso means? The stomach and the chest. The whole middle part of the body.

15. F rog lungs are poorly developed. How does this relate to their skin being thin and moist?
It helps with their breathing.
16. Name 2 ways forelimbs are different than hind limbs.
Hind limbs tend to be sturdier.
Critical Thinking Questions
17. Frogs produce a huge number of babies at one time WHY do you think this is (HINT: Finding
Nemo)?
Because if there is a predator the predator will take some and there will probably be
one left.
18. The frogs tongue is anchored in the very front opposite to the orientation and anchoring of
humans. Why do you think this is so
So the frogs can stick out their tongue longer and quickly so they can catch flies.
