1. A sea sponge can reproduce asexually. If cut in half, the sponge can grow into two new
identical sponges. Which of the following statements is true about the new sponges?
A. The DNA of the new sponge is a new unique strand of DNA.
B. The DNA of the new sponge is a blend of the parent sponge’s DNA.
C. The DNA of the new sponge is the same as the DNA of the parent sponge.
D. The DNA of the new sponge is different from the DNA of the parent sponge.
2. A scientist discovers a new organism. The scientist observes that when this organism
reproduces, two parents are involved and the offspring have DNA that is similar to the
parents but not identical. What kind of reproduction does this organism use?
A. Asexual reproduction
B. Sexual reproduction
C. Regeneration
D. Pollination
3. A plant with pink flowers is crossed with a plant with orange flowers. Three of the offspring
have orange flowers, and one offspring has pink flowers.
Which statement explains why this occurred?
A. The plant with the pink flowers only received genes from the parent with pink flowers.
B. The plant with the pink flowers only received genes from the parent with orange flowers.
C. The offspring received the genes from both parents, but pink color is the dominant trait.
D. The offspring received the genes from both parents, but pink color is the recessive trait
4. A dog with curly fur is crossed with a dog with smooth fur. All of the offspring have curly
fur.
Which statement explains why this occurred?
A. The offspring received the genes from both parents, but curly fur is the dominant trait.
B. The offspring received the genes from both parents, but curly fur is the recessive trait

Is the cell in the diagram to the right a prokaryotic cell? (DOK 3)
Yes, because there are complex organelles like a nucleus.
Yes, because it is simple and the only organelles it has are ribosomes.
No, because it is simple and the only organelles it has are ribosomes.
No, because it is an animal cell.
