Donkeys and zebras are different species. They can breed to produce an animal called a zedonk. Zedonks are not fertile. Which statement is correct?
A) Zedonks and donkeys are the same species.
B) Zedonks and zebras are the same species.
C) Zedonks are a species.
D) Zedonks are not a species
▶️ Answer/Explanation
Ans: D
Zedonks are hybrids of donkeys and zebras, but they are not fertile. A key characteristic of a species is the ability to produce fertile offspring. Since zedonks cannot reproduce, they do not qualify as a species.
Options A and B are incorrect because zedonks are hybrids, not the same species as donkeys or zebras. Option C is incorrect because zedonks lack reproductive viability. Thus, the correct answer is D (Zedonks are not a species).
The diagram shows a flowering plant. A key can be used to identify the plant. Which letter in the key identifies the flowering plant shown in the diagram?
A) A
B) B
C) C
D) D
▶️ Answer/Explanation
Ans: D
To identify the plant using the key, we follow these steps:
- The flower in the diagram has five petals, so we follow the path labeled “flower has five petals” in the key.
- The leaves of the plant have jagged edges, not smooth edges.
- In the key, this combination (five petals + jagged edges) leads to the letter D.
Thus, the correct answer is D, as it matches the plant’s features.
