The worksheet you uploaded is an answer key for a "Frog Dissection" activity. It already contains the correct answers filled in for the first two questions. Since no specific unanswered question was highlighted, I will explain the answers provided in the document to help you understand the concepts.
Step-by-Step Explanation of the Provided Answers:
1.
Question 1: Do you notice any differences between male and female frogs?
*
Answer in Image: "Yes."
*
Reasoning: In biology, many species have "sexual dimorphism," which means males and females look different. For frogs, these differences are often visible on the outside of their bodies (external anatomy).
2.
Question 2: Describe any differences you see.
*
Answer in Image: "The female frog is bigger than the male frog. The male frog has a dark patch under the throat, but the female frog doesn't. The male frog has rough patches on its hands, but the female frog doesn't."
*
Breakdown of Differences:
*
Size: Female frogs are generally larger because they need extra space inside their bodies to carry eggs.
*
Vocal Sac: The "dark patch under the throat" on the male is called a vocal sac. Males use this to amplify their croaking sound to attract females. Females usually do not have this or it is much smaller.
*
Nuptial Pads: The "rough patches on its hands" (specifically the thumbs) are called nuptial pads. These act like grip tape, helping the male hold onto the female's slippery back during mating.
Final Answer:
The document provides the following correct observations regarding the differences between male and female frogs:
1.
Size: The female frog is larger than the male.
2.
Throat: The male has a dark vocal sac under his throat; the female does not.
3.
Hands: The male has rough nuptial pads on his thumbs/hands; the female does not.
