Answer the following question given this paragraph: As larvae, tunicates can swim freely to find food. As adults, tunicates lack a post-anal tail and notochord, and they can no longer swim. Instead, they remain in one place and are filter feeders. Tunicates can reproduce both sexually and asexually. The same adults produce sperm and eggs. However, fertilization always involves gametes from different parents. Asexual reproduction is by budding. Q: Budding is a form of what type of reproduction in tunicates? Choices: - sexual - nuclear - microscopic - asexual A:
(A).
asexual

Answer the following question given this paragraph: Figure 46.15 Carbon dioxide gas exists in the atmosphere and is dissolved in water. Photosynthesis converts carbon dioxide gas to organic carbon, and respiration cycles the organic carbon back into carbon dioxide gas. Long-term storage of organic carbon occurs when matter from living organisms is buried deep underground and becomes fossilized. Volcanic activity and, more recently, human emissions, bring this stored carbon back into the carbon cycle. (credit: modification of work by John M. Evans and Howard Perlman, USGS). Q: Respiration cycles the organic carbon into which gas? Choices: - liquid dioxide - phosphorus dioxide - oxygen - carbon dioxide A:
(A).
carbon dioxide
