Answer the following question given this paragraph: Introduction to Two-Dimensional Kinematics The arc of a basketball, the orbit of a satellite, a bicycle rounding a curve, a swimmer diving into a pool, blood gushing out of a wound, and a puppy chasing its tail are but a few examples of motions along curved paths. In fact, most motions in nature follow curved paths rather than straight lines. Motion along a curved path on a flat surface or a plane (such as that of a ball on a pool table or a skater on an ice rink) is two-dimensional, and thus described by two-dimensional kinematics. Motion not confined to a plane, such as a car following a winding mountain road, is described by three-dimensional kinematics. Both two- and threedimensional kinematics are simple extensions of the one-dimensional kinematics developed for straight-line motion in the previous chapter. This simple extension will allow us to apply physics to many more situations, and it will also yield unexpected insights about nature. Q: Most motions in nature follow ________ rather than straight lines? A:
OPTIONS:
- vertical paths
- sharp paths
- horizontal paths
- curved paths

Answer: curved paths

Question: Answer the following question given this paragraph: Roots are vascular organs that can penetrate soil and even rock. They absorb water and minerals from soil and carry them to leaves. They also anchor a plant in the soil. Roots evolved from rhizoids, which nonvascular plants had used for absorption. Q: What did roots evolve from that plants used for aborption? A:
OPTIONS:
- seeds
- leguminous
- oomycetes
- rhizoids
Answer: rhizoids

input with options: Answer the following question given this paragraph: Covalent bonds are bonds in which atoms share rather than transfer electrons. Compounds with covalent bonds are called covalent compounds. Q: What do you call compounds that have covalent bonds? A:
OPTIONS:
- reflectivity compounds
- valence compound
- ions
- covalent compounds
output: covalent compounds

Q: Answer the following question given this paragraph: Q: What is the scientific term for the act of eating or feeding? A:

OPTIONS:
- secretion
- excretion
- swallowing
- ingestion

A: ingestion

input: OPTIONS:
- cluster
- tuck
- spasm
- clade Now, answer this question: Answer the following question given this paragraph: One way of classifying organisms that shows phylogeny is by using the clade. A clade is a group of organisms that includes an ancestor and all of its descendants. Clades are based on cladistics. This is a method of comparing traits in related species to determine ancestor-descendant relationships. Clades are represented by cladograms, like the one in Figure below . This cladogram represents the mammal and reptile clades. The reptile clade includes birds. It shows that birds evolved from reptiles. Linnaeus classified mammals, reptiles, and birds in separate classes. This masks their evolutionary relationships. Q: What is one way of classifying organisms called? A:
A:
output: clade

Question: Answer the following question given this paragraph: The attractive force between water molecules is a dipole interaction. The hydrogen atoms are bound to the highly electronegative oxygen atom (which also possesses two lone pair sets of electrons, making for a very polar bond. The partially positive hydrogen atom of one molecule is then attracted to the oxygen atom of a nearby water molecule (see Figure below ). Q: The attractive force between water molecules is what kind of reaction? A:
OPTIONS:
- symmetrical reaction
- aquatic reaction
- diffusion reaction
- dipole reaction
Answer:
dipole reaction
