A node represents a shared derived trait that defines a clade of animals that share it. Group of answer choices A: True B: False

Which of the following traits is more associated with an Opportunistic (Equilibrial) species?  Which of the following traits is more associated with an Opportunistic (Equilibrial) species?   A. Short maturation time   B. Producing offspring at many different times over the course of life   C. Producing a lot of eggs at one time   D. High juvenile mortality   E. High level of parental care

Imagine three islands, each with a population of frogs. There are approximately 1,100 frogs on Island 1, 400 on Island 2, and 400 on Island 3. Researchers estimate that these populations have been separated for 800 years. Individuals in these populations show variation in markings on their body by shape and color. Frogs on Islands 1 and 2 have circle markings that are either red, blue, or purple. All frogs on Island 3 have yellow triangle markings.  The islands recently became a tourist destination, with new passenger boats connecting Island 1 and Island 2, and Island 1 and Island 3 (there is no boat that goes between Island 2 and Island 3).   Would a biologist agree or disagree with the following statements?  part 1:  It is possible that yellow or triangle markings exists on Island 1 at some point in the past. Question options:   Agree   Disagree part 2:  Genetic drift is not occurring on Island 1.   Question options:…

Please complete the following short-answer question:

Figure 4. This map shows the range of five different bird species in North America based on data collected from 1980 to 1995.  For each statement, select TRUE if it is consistent, or FALSE if it is not consistent with the information presented above.  Fossil evidence suggests that Bird F and Bird X once shared a common ancestor that predates the formation of the mountains that separate them. This evidence is consistent with vicariance in these two species.    Question 13 options:   True   False

How do hatcheries (i.e. farmed salmon) impact wild salmon population genetics? A: Increase species variability between different populations B: Decrease the resilience of wild populations C: Decrease mixing between different populations D: Overcrowd streams when they return to where they were spawned

Construct a phylogenetic tree.

Pretend you are a scientist observing three different varieties of a single bird species that are part of the same population. In three to five sentences, describe what genetic variations exist in your population. Then, using reasoning skills and mock evidence from your observations, describe the impact these traits have on the birds’ relationships with their environment and predators.

Which of the following could attribute to variation within a species?  Choose all that apply.   Question 4 options:   phenotypic plasticity   age   ontogeny   sexual dimorphism   morphology

Multiple outgroups confuse the process of polarising characters. Select one: True or False
