Answer the following question given this paragraph: ingest their food and usually develop into motile creatures with a fixed body plan. Most members of the animal kingdom have differentiated tissues of four main classesnervous, muscular, connective, and epithelialthat are specialized to perform different functions. Most animals reproduce sexually, leading to a developmental sequence that is relatively similar across the animal kingdom. Organisms in the animal kingdom are classified based on their body morphology and development. True animals are divided into those with radial versus bilateral symmetry. Animals with three germ layers, called triploblasts, are further characterized by the presence or absence of an internal body cavity called a coelom. Animals with a body cavity may be either coelomates or pseudocoelomates, depending on which tissue gives rise to the coelom. Coelomates are further divided into two groups called protostomes and deuterostomes, based on a number of developmental characteristics. Q: Most members of the animal kingdom have differentiated tissues of four main classesnervous, muscular, connective, and this? A:
OPTIONS:
- neural
- crystalline
- digestive
- epithelial
epithelial

Answer the following question given this paragraph: Cleavage is the tendency of a mineral to break along certain planes. When a mineral breaks along a plane, it makes a smooth surface. Minerals with different crystal structures will break or cleave in different ways ( Figure below ). Halite tends to form cubes with smooth surfaces. Mica tends to form sheets. Fluorite can form octahedrons. Q: What term is used to describe the tendency of a mineral to break along certain planes? A:
OPTIONS:
- tooth decay
- porosis
- erosion
- cleavage

Answer: cleavage

Question: Answer the following question given this paragraph: An ionic bond forms when the metal sodium gives up an electron to the nonmetal chlorine. Q: What forms when the metal sodium gives up an electron to the nonmetal chlorine? A:
OPTIONS:
- covalent bond
- van der waals force
- hydrogen bond
- an ionic bond
Answer: an ionic bond

input with options: Answer the following question given this paragraph: Centipedes and millipedes belong to the subphylum Myriapoda, which contains 13,000 species. They all live on land, which makes sense as all those legs are more adapted to a terrestrial lifestyle, as opposed to an aquatic lifestyle. Q: Not surprisingly, centipedes, millipedes and other members of the subphylum myriapoda are adapted to living on what? A:
OPTIONS:
- water
- sand
- tree
- land
output: land

Q: Answer the following question given this paragraph: Sponges have an internal skeleton that gives them support and protection. An internal skeleton is called an endoskeleton . A sponge endoskeleton consists of short, sharp rods called spicules (see Figure below ). Spicules are made of silica, calcium carbonate, or spongin, a tough protein. They grow from specialized cells in the body of the sponge. Q: Sponges possess an internal skeleton called what? A:

OPTIONS:
- hydrostatic skeleton
- fluid skeleton
- exoskelton
- endoskeleton

A: endoskeleton

Answer the following question given this paragraph: 15.2 Sponges and Cnidarians Animals included in phylum Porifera are parazoans and do not possess true tissues. These organisms show a simple organization. Sponges have multiple cell types that are geared toward executing various metabolic functions. Cnidarians have outer and inner tissue layers sandwiching a noncellular mesoglea. Cnidarians possess a well-formed digestive system and carry out extracellular digestion. The cnidocyte is a specialized cell for delivering toxins to prey and predators. Cnidarians have separate sexes. They have a life cycle that involves morphologically distinct formsmedusoid and polypoidat various stages in their life cycle. Q: Porifera are parazoans that exhibit simple organization and lack true what? A:
OPTIONS:
- molecules
- nuclei
- cell membranes
- tissues
tissues
