David comes into the emergency room late at night with a cut that will not stop bleeding. His mother, Rose, is worried that he has a bleeding disorder, just like his grandfather. The lab is closed, so the doctor cannot order a specialized coagulation test. However, the hospital does have a sample of blood from a classic hemophiliac. What is the simplest test the doctor could perform using David's blood to determine if it is missing factor VIII activity

A student crosses a pure-breeding line of red-flowered poinsettias with a pure-breeding line of white-flowered poinsettias. The student observes that all the plants in the F1 generation have pink flowers. The student then crosses the F1 plants with one another and records 64 red-flowered plants, 107 pink-flowered plants and 53 white-flowered plants. What is the inheritance pattern for flower color in these poinsettias

In Drosophila, red eyes is wild-type and purple eyes are mutant. Full-size wings are wild-type and vestigial wings are mutant. Flies with wild-type pr pr vg vg genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes. The F1 flies had pr pr- vg vg- genotypes. The F1 flies with heterozygous genotypes were crossed with double mutant flies with a pr-pr- vg-vg- genotypes One thousand offspring were typed. This cross produced 430 red-eye, wild-type wing flies, 65 purple-eye wild-type wing flies, 60 red-eye, vestigial wing flies, and 445 purple-eye, vestigial wing flies. What is the distance between the loci for purple eyes and vestigial wings in centiMorgans (map units)

Starting with the European settlers, humans have introduced earthworms from Europe and Asia into North American forests. These introductions continue through the transport of soil that contains non-native earthworms, such as during construction and through the release of non-native earthworms used for fishing. The effects of non-native earthworms are especially large in forests that did not have any native earthworms. For example, forests of the Great Lakes region did not previously have earthworms until humans introduced them. When non-native earthworms are introduced, the thick layer of leaf litter disappears quickly, thereby altering biogeochemical cycles. You conduct an experiment to compare the nitrogen cycle in soils with and without non-native earthworms. Predict the results of your experiment.

A group of researchers has made the claim that one particular butterfly species is the sole pollinator of a tree species and that consequently, the decline of the butterfly population will endanger the survival of the tree species. Data were collected and are summarized below. Which of the following data could best be used to either justify or refute the claim the researchers have made about the interdependence of the butterfly species and the trees?

Tree flower size Number of butterfly visits per flower per day Nectar energy per pollination visit (joules) Fruits per flower
Small 1 10 0.88
Medium 9 12 0.79
Large 55 13 0.85

a. The data comparing the fruits produced per flower with the number of butterfly visits are most useful in refuting the claim, because they show that the tree produces fruit even if the butterfly does not visit the flowers.
b. The data collected for large flowers are most useful in justifying the claim, because they show that a large number of butterflies visit flowers of this tree species, obtain energy from nectar, and cause fruit production.
c. The data comparing the number of butterfly visits with the size of the tree flowers are most useful in refuting the claim, because they show that the butterfly does not visit all types of tree flowers.
d. The data showing the nectar energy available for all sizes of flowers are most useful in justifying the claim, because they show that butterflies benefit from the relationship with the tree by obtaining energy from tree nectar.

All of the following are true about thymine dimers EXCEPT: the type of repair that is done to fix them is called nucleotide excision repair they are caused by UV radiation damage that fuses thymines that are next to each other on the same strand individuals with xeroderma pigmentosa (XP) are unable to repair this type of DNA damage, leading to cancer cell development they are caused by UV radiation damage to thymines that are opposite each other on different DNA strands
