Question
You could kill a starfish by cutting off its arms. Reptiles never have gill slits. The heart of an adult amphibian has three chambers. Phloem transports organic nutrients from leaves to roots. Sieve tube members are found in xylem. Tracheids are a type of cell in phloem. Xylem transports water from roots to leaves. Sponges have three tissue layers. Higher plants have a minute diploid phase. Many fungi depend on plants for mineral absorption. If lichen were sprayed with a chemical that blocked photosynthesis, it would probably die. The insects include more species than any other group.Explanation / Answer
27] You kould kill a starfish by cutting of its arms
