Darwin's Bark Spider Claims
Question: Why do traits for silk
flexibility vary within this family of
Darwin's bark spiders?
Remember these are claims about why
the trait for silk flexibility varies within
the spider family.
Claim 1: The offspring have
mutations that affect their traits.
Do we have enough
evidence to support or
eliminate any of the
claims? WHY OR WHY
Claim 2: The offspring's traits
depend on which parent the
offspring received more traits
from.
Claim 3: The offspring received
different combinations of traits
from their parents.
NOT?

Which of the following statements about the "tree of life" is correct?
Before Carl Woese, all cellular life forms were classified into five kingdoms: Monera, Fungi, Plants, Animals, and Protists.
Using rRNA genes for phylogenetic reconstruction, Carl Woese uncovered a previously unrecognized group that was thought to be bacteria. Afterward, all cellular life forms were classified into three domains: Archaea, Bacteria, and Eucarya.
It is found that the relationship among Archaea, Bacteria, and Eucarya changes, depending on which gene was used for phylogenetic reconstruction.
All of the above
Use the hybrid selection model, OY = ky(1 - y)(a - by), to find the percent of the population that has the given characteristic.

A research team is studying a population of snails to determine how quickly characteristic B will pass from one generation to the next. At the start of the study, 20% of the snails have characteristic B. After five generations, 81% of the population has characteristic B. Find
the percent of the population that will have characteristic B after eight generations. (Assume a = 2 and b = 1. Round your answer to the nearest whole number.)

Consider a species that occupies a large, but fixed, number of islands. The distribution of the species across all islands is maintained by a balance between local extinctions and local colonization events. Devise a model for the relationship between the fraction of islands occupied by the species and time. Be clear to outline the assumptions you make and be sure to describe your key predictions.arrow_forwardINSTRUCTIONS: Use the words in the box below to fill in the blanks based on what you have learned about the adaptations of species.

Word Bank Selective breeding Hybrid Population Real Crop species Diverse Traits Domestic Uniform Artificial CLOZE 3 occurs when humans take control of the breeding process. The favorable to be passed on are chosen by the breeder to create a new or improved variety. Farmers have bred like corn, to produce more food in a smaller area. These plants result by crossing parent plants for their desired traits. animals, like dog breeds, have also been bred to be incredibly compared to the diversity of their ancestors. This selecting of traits is also known as selection. Similar to natural selection, the of a species changes over time, and some traits become more common.arrow_forward
