Please match each of the words in the attached image.

Look up 5 other species that are in the same order as your species and create a dichotomous key that could be followed to ID your species.  SPECIES: Panda

Consider the following sample dataset of character traits for five taxa (A, B, C, D, and E) and an outgroup (O) and answer the following: Taxon, Character 1 A B C D 1 1 1 0 0 Character 2 0 0 0 1 1 0 Character 3 1 1 0 0 0 0 Character 4 1 1 1 0 0 0 (A) Identify which character traits are ancestral and which are derived, (B) Determine the two taxa most closely related to each other (C) Are any of the character traits obvious homoplasies? If so, which ones? (D) Name three taxa that if put in their own taxonomic group would be considered paraphyletic.

1. Complete the following table.  A single value is given for each of five species (A-E); fill in the rest of the values for each species.  However: one species’ values are not possible!   2. The value for which species is not possible? ______   Explain why:

Based on the traits in the table below, which of the following would be the most parsimonious arrangement of species on the tree below? List species from top to bottom, following the arrow on the right.

Explain your answer in some depth and avoid just saying "It is A" or It is B. Defend your answer and explain why you choice that answer choice.    Question: Which would be an example of two populations considered separate species based on the lineage species concept? Group of answer choices   A) Two squirrel populations in which one was red and the other was brown   B) Two warbler populations in which the females strongly prefer to mate with males of the same population   C) Two plant populations that are capable of producing fertile hybrids   D) Two dragonfly populations that have accumulated several differences in their DNA sequences       Question: Which mechanism can lead to selection against hybridization? Group of answer choices A) Hybrid sterility   B) Mechanical isolation   C) Gametic isolation   D) Temporal isolation   E) Behavioral isolation   Which of the following results from the uneven heating of land masses and creates winds that blow from low to high elevation?  Group…

Think about the ways we define/identify a species. What would the least precise way to determine a living species (so not extinct)? O groups of organisms that look alike O groups of organisms that are geographically separated for a significant period of time such that they become distinct genetically separate populations with different genetic markers groups of potentially interbreeding populations with are reproductively isolated from others
