Practice Questions for FALL FINAL Biology (Ms. Kennedy): REVISED DECEMBER 2010 KEY Note: These are a few sample questions that you can work through for more practice with genetics and experimental design. You should also review the evolution and experimental design quizzes and exams. These questions do NOT cover all of the material covered this semester. Completion of these questions alone will not be sufficient preparation for the final exam. Use the diagram below for #1: The arrangement of

Evolution of Australian Biota 1. Evidence for the rearrangement of crustal plates and continental drift indicates that Australia was once part of an ancient super continent Identify and describe evidence that supports the assertion that Australia was once part of a landmass called Gondwana including: Matching continental margins Gondwana once consisted of South America‚ Africa‚ Madagascar‚ India‚ Antarctica‚ Australia‚ New Zealand and New Guinea. Continental margin: zone between the ocean basin

The amount of time involved will depend on how quickly the ovaries respond and whether the woman has polycystic ovaries. Polycystic ovaries are more likely to over or under respond and therefore it might take some weeks before ovulation successfully occurs. We expect a pregnancy rate of 15 to 40%‚ depending on the woman’s age. Artificial Insemination using Partner’s Semen (IUI) This is a treatment that combines a small amount of ovarian stimulation‚ to maximise the maturity of the egg and the lining

Unit 2 – Evolution Steps Leading Up to Charles Darwin’s Theory ü Around the world‚ there is an enormous diversity of life Each species has its own set of characteristics Arctic animals – have characteristics that help them survive in the cold‚ harsh environment Desert animals – have characteristics that help them survive in the extreme heat ü Theory is a set of statements that explains a group of facts or phenomena Tested repeatedly and supported by evidence Can be used to make predictions

Fertilization: The Journey of Cassandra and Euripides David Mohr Fertilization: The Journey of Cassandra and Euripides One of the most awesome things that our bodies can do is produce another human being. This is a vital process in keeping our species alive. The steps to fertilization not only take place inside the body but outside the body as well. The internal and external sex organs of the male and female will be called upon to participate in the fertilization process. There are many

Genetics Experimental Analysis Set #2 Linkage 1. In gorgonzolas‚ there are three recessive traits that affect the organism’s appeal: shrunken fruit‚ foul-smelling flowers‚ and short height. A heterozygote was crossed with a homozygote‚ yielding the following offspring: 46 - foul-smelling 44 - shrunken fruit‚ short height 8 - short height 8 - shrunken fruit 7 - foul-smelling‚ short height 6 - foul-smelling‚ shrunken fruit 3 - foul-smelling‚ shrunken fruit‚ short

A controversial issue of the twenty-first century is the possible application of new techniques in genetic engineering to produce human clones. Up until now genetic engineering and cloning has been used to clone plants‚ unicellular organisms‚ amphibians and simple mammals. This has led to significant advances in agriculture‚ industry‚ and medicine. Newer techniques in genetic engineering have enabled scientists to clone more complex mammals and opened up the possibility of cloning humans. Although
