The crab spider, Thomisus spectabilis, sits on flowers and preys upon visiting honeybees. Do honeybees distinguish between flowers that have crab spiders and flowers that do not? To test this, Heiling et al. (2003) gave 34 bees a choice between 2 flowers: one with, and one without a crab spider. In 24 of the 34 trials, the bees picked the flower that had the spider. In the other trials, the bees chose the spiderless flower. With these data, carry out the appropriate hypothesis test (one- or two-tailed), using the normal approximation to the binomial distribution to determine Z. For a one-tailed test, use the formula =(1-NORM.DIST(Z,0,1,TRUE) in Excel calculate P. For a two-tailed test, use the formula =2(1-NORM.DIST(Z,0,1,TRUE). State your answer for the value of P to three decimal places, and include the leading zero. Do all of the math in Excel DO NOT round the value of Z. Substitute the cell (e.g. B1) for Z in the formula for P.

(A) Genetic uniformity of a crop increases the crop’s overall resistance to pests and disease. (B) Genetic resistance to pests and diseases can be increased by crossing a crop plant with ancestral varieties. (C) Genetic engineering technology is used to increase genetic diversity by creating new species with synthetic genes. (D) Genetic diversity within populations of common crop species such as corn is typically high. (E) Genetic diversity is usually high in endangered species.

I need the circle data info, thanks!

You are mapping three loci in Brandywine apricot trees (Prunus brandybucki), an important agricultural species in the Shire.  In Brandywine apricot trees, sour fruit (fr+) is dominant to fishy-tasting fruit (fr), blue flowers (b+) is dominant to yellow flowers (b), and short, bushy height (sh+) is dominant to tall, tree-like height (sh).  You perform a testcross with a plant that is heterozygous for all three loci and get the following offspring:   Fruit flavor Flower color Plant height Observed Counts fr+ b+ sh+ 61 fr b sh 53 fr+ b+ sh 11 fr b sh+ 7 fr+ b sh 277 fr b+ sh+ 285 fr+ b sh+ 156 fr b+ sh 150     Total 1000     What is the recombination frequency between b and sh?

10) The following figure describes results from an experiment in which brood size in breeding European kestrels was manipulated. Which of the following statements are supported by these results? Flight (hours/day) Adult survival rate (%) 007 CO 10 3 cu 1 0 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 T 1 Female Question 10 options: • Male 2 3 4 5 6 Brood size (number of chicks) 1 7 Survival of adult males decreased with increasing brood size. Females spent more time foraging (measured as hours spent daily in flight) than did males. Brood size decreased with date (i.e., late season broods were smaller than early season broods).
