Answer the following question given this paragraph: Classification and Phylogeny Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and relationships between organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms. The hierarchical classification of groups nested within more inclusive groups is reflected in diagrams. Scientists consider phylogenetic trees to be a hypothesis of the evolutionary past because one cannot go back through time to confirm the proposed relationships. Unlike with a taxonomic classification, a phylogenetic tree can be read like a map of evolutionary history, as shown in Figure 12.4. Shared characteristics are used to construct phylogenetic trees. The point where a split occurs in a tree, called a branch point, represents where a single lineage evolved into distinct new ones. Many phylogenetic trees have a single branch point at the base representing a common ancestor of all the branches in the tree. Scientists call such trees rooted, which means there is a single ancestral taxon at the base of a phylogenetic tree to which all organisms represented in the diagram descend from. When two lineages stem from the same branch point, they are called sister taxa, for example the two species of orangutans. A branch point with more than two groups illustrates a situation for which scientists have not definitively determined relationships. An example is illustrated by the three branches leading to the gorilla subspecies; their exact relationships are not yet understood. It is important to note that sister taxa share an ancestor, which does not mean that one taxon evolved from the other. The branch point, or split, represents a common ancestor that existed in the past, but that no longer exists. Humans did not evolve from chimpanzees (nor did chimpanzees evolve from humans) although they are our closest living relatives. Both humans and chimpanzees evolved from a common ancestor that lived, scientists believe, six million years ago and looked... Q: What diagram is used to reflect evolutionary relationships among organisms or groups of organisms? A:

- relationships tree
- conceptual tree
- biodiversity tree
- phylogenetic tree

Answer: phylogenetic tree

Question: Answer the following question given this paragraph: For machines that change only the direction of the force, such as the rope systems on flagpoles, the output force is the same as the input force. Therefore, the mechanical advantage is equal to 1. Q: If a machine only changes the direction of a force without changing the ratio of the output/input forces, then what is its associated mechanical advantage? A:
OPTIONS:
- 4
- 1.5
- 2
- 1
Answer: 1

input with options: Answer the following question given this paragraph: Bacteria can be used to make cheese from milk. The bacteria turn the milk sugars into lactic acid. The acid is what causes the milk to curdle to form cheese. Bacteria are also involved in producing other foods. Yogurt is made by using bacteria to ferment milk ( Figure below ). Fermenting cabbage with bacteria produces sauerkraut. Q: Bacteria can be used to make cheese from milk. the bacteria turn the milk sugars into what? A:
OPTIONS:
- acetic acid
- ionic acid
- hydrochloric acid
- lactic acid
output: lactic acid

Q: Answer the following question given this paragraph: Types of friction include static friction, sliding friction, rolling friction, and fluid friction. Fluid friction with air is called air resistance. Q: What is fluid friction with air called? A:

OPTIONS:
- buoyancy
- wind resistance
- gravity
- air resistance

A: air resistance

Answer the following question given this paragraph: Mole fractions describe the fraction or percentage of a mixture that is made up of a particular substance. Q: What describe the fraction or percentage of a mixture that is made up of a particular substance. A:
OPTIONS:
- molecular scale
- atomic weight
- solute level
- mole fractions
mole fractions
