Answer the following question given this paragraph: Frogs typically lay their eggs in puddles, ponds, or lakes. Their larvae, or tadpoles , have gills, a tail, but no legs, and need to live in water. If fact, they are quite similar to a fish. Tadpoles develop into adult frogs in water ( Figure below ). During this transformation, they develop lungs, lose their tails and form their four legs. Q: What to tadpoles develop into? A:
OPTIONS:
- toads
- mosquitos
- snakes
- frogs

Answer: frogs

Question: Answer the following question given this paragraph: 8.2 Chromatin Chromosomes consist of chromatin11 . This is made up of strings of DNA, which typically measure centimeters in length if stretched out. This DNA is wound around a histone12 core and organized into nucleosome13 s. The chromatin14 must be uncoiled for gene expression15 and replication16 . Chromosome micrograph. Q: Chromosomes consist of what material made up of strings of dna? A:
OPTIONS:
- mitochondria
- gray matter
- rna
- chromatin
Answer: chromatin

input with options: Answer the following question given this paragraph: Covalent Solids Covalent solids are formed by networks or chains of atoms or molecules held together by covalent bonds. A perfect single crystal of a covalent solid is therefore a single giant molecule. For example, the structure of diamond, shown in part (a) in , consists of sp3hybridized carbon atoms, each bonded to four other carbon atoms in a tetrahedral array to create a giant network. The carbon atoms form six-membered rings. Figure 12.19 The Structures of Diamond and Graphite. Q: Covalent solids are formed by networks or chains of atoms or molecules held together by what? A:
OPTIONS:
- ionic bonds
- bail bonds
- gravitational bonds
- covalent bonds
output: covalent bonds

Q: Answer the following question given this paragraph: Many turtles are aquatic. They may live in the ocean or in fresh water. Other turtles are terrestrial and live on land. All lizards are terrestrial. Their habitats may range from deserts to rainforests. They may live in a range of places, from underground burrows to the tops of trees. Most snakes are terrestrial, but some are aquatic. Crocodilians live in and around swamps or bodies of water. The water may be fresh or salty, depending on the species of crocodilian. Q: Name the two types of water turtles live in. A:

OPTIONS:
- arctic water and ice water
- ocean water and sea water
- river water and lake water
- ocean water and fresh water

A: ocean water and fresh water

Answer the following question given this paragraph: A polyatomic ion is an ion composed of more than one atom. For example, the ammonium ion consists of one nitrogen atom and four hydrogen atoms. Together, they comprise a single ion with a 1+ charge and a formula of NH 4 + . The carbonate ion consists of one carbon atom and three oxygen atoms, and it carries an overall charge of 2. The formula of the carbonate ion is CO 3 2- . The atoms of a polyatomic ion are tightly bonded together, so the entire ion behaves as a single unit. Figure below shows several models, and Table below lists many of the most common polyatomic ions. Q: A polyatomic ion is an ion composed of more than one what? A:
OPTIONS:
- pair bond
- neutron
- nucleus
- atom
atom
