The answers provided to your questions are correct, so we could say they are "true" in the context of being correct responses to the questions. Here’s a brief justification for each one:

  1. Question 1: "All animals have DNA." - True. All living organisms, including animals, plants, fungi, and bacteria, have DNA as their genetic material.
  2. Question 2: "breathe with lungs or gills" - True. Vertebrates typically have lungs (like mammals) or gills (like fish) for breathing.
  3. Question 3: "both are invertebrates" - True. Starfish (echinoderms) and snails (mollusks) are both classified as invertebrates since they do not have a backbone.
  4. Question 4: "Animals consume other organisms." - True. One key distinction between animals and plants is that animals are heterotrophic, meaning they obtain energy by consuming other organisms, while plants are typically autotrophic, producing their own food through photosynthesis.

Overall, the answers you provided to the quiz questions are accurate.
