Trivia: In every beehive, there is one queen bee who lays all the eggs. If an egg is not fertilized, it hatches into a male bee, called a drone. If an egg is fertilized, it hatches into a lady worker bee, which does not lay any eggs. a. Consider a drone. How many parents, grandparents, great grandparents, great-great-grandparents, great-great-great-grandparents, great-great-great-great grandparents does it have? b. Write a mathematical sentence that can be used to represent the number of grandparents a drone has during a particular generation.

Voles that are born in the Spring have thin coats as adults, while voles that are born in the Fall have thick coats as adults. Most voles live only a few months; voles born in the Spring are alive during the warm summer season, while voles born in the Fall are alive during the cold winter season. The environment experienced by the mother during pregnancy determines coat thickness in the offspring. Now consider a situation in which the environment the vole mothers during pregnancy changes, such that voles born in the Fall now have thin coats. Assume in this case that the Winters are still cold. This scenario provides an example of which of the following hypotheses?   a.Environment mismatch hypothesis  b.Endocrine disruptor hypothesis c.Thrifty genotype hypothesis d.Plasticity first hypothesis

Let's go back to the image from the "Think About It." Use your new vocabulary, evidence from the lessons, and scientific reasoning to support the claim, "While there are many types of asexual reproduction, all types result in offspring identical to each other and the original parent." You may include a model or sketch as support for the claim. Submit your optional hand-drawn or digital model or sketch in the file upload question. B I iii !!! (a) (b) (C) (d) (e)
