You will create a molecular clock model for an arthropod gene. Follow these guidelines to make your model: • Your timeline will span from 90 million years ago to the present. The common ancestor in your model is an arthropod that lived 90 million years ago. The gene that you’ll track codes for a protein in the species’ venom.
• The DNA sequence you’ll track contains 10 nitrogen bases. You can choose the order of the bases and where the mutations occur. • This gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. To build your model, calculate the estimated time period it takes for 1 base pair to mutate.
• The first time period will only show the common ancestor. At the beginning of the second time period, three lineages will diverge from the common ancestor, each with a different mutation in their gene sequences.
• The first and third descendant species will survive for the rest of the timeline. The second descendant species was extinct 50 million years ago.
Calculate how long it will take for one full base pair mutation to occur. Explain your reasoning by constructing a mathematical equation.

Populations of blue-winged warblers, a type of bird, migrate south in the winter and return to canadian breeding grounds in the spring. as global temperatures have increased due to climate change, spring has started arriving in the warbler's breeding grounds earlier in the year, before the warblers return. warblers now arrive at their breeding grounds too late to select ideal nesting sites and to feed on important early-spring food sources how are populations of blue-winged warblers most likely to be affected by the earlier arrival of spring? o a. populations will go extinct since the warblers will stop migrating to breeding grounds. b. populations will be unaffected since most species can quickly adapt to effects of climate change. c. populations will increase since warmer temperatures are generally beneficial to survival, d. populations will decline since individuals will be less likely to successfully reproduce, reset next

Ascientist discovers a new body between the orbit of neptune and the kuiper belt. the object is round and travels in an orbit around neptune with other space objects. the scientist claims that she has found a new dwarf planet. where is the scientist’s error? the object is an asteroid, not a dwarf planet.the object is a moon, not a dwarf planet.the object is not a dwarf planet because it travels with other objects.the object is not a dwarf planet because it is round.
