Bell Ringers: Week of 17 Mar – 21 Mar 2008 CST Review Questions Monday –Which of the following explains why natural selection acts on the phenotype of an organism instead of its genotype? A Phenotypes directly influence the interaction of an organism with its environment. B Genotypes do not change except by the process of transcription. C Genotypes change in direct response to habitat changes. D Phenotypes can be inherited by offspring. Explain

The inheritance of a trait in humans is best described as being determined by ________________ A a single allele. B one or more pairs of alleles. C one pair of chromosomes. D the sex chromosomes of the offspring. Explain

Tuesday - In pigeons, the allele for normal feathers (F) is dominant to the allele for frizzy feathers (f). If a purebred, normal-feathered bird (FF) is crossed with a frizzy-feathered bird (ff), how many different feather phenotypes are possible in the offspring? A 1 B 2 C 3 D 4 Explain

Which of the following processes allows the cells of an organism to use carbon from the environment? A mitosis B fertilization C transpiration D photosynthesis Explain

Wednesday – How is natural selection in the evolution of long necks in giraffes best explained? A Shorter-necked giraffes were killed by long-necked giraffes. B Giraffe necks grew longer because of the bone structure of the animals. C Giraffes with longer necks survived because they were better suited to the environment. D Long-necked giraffes mated only with other long-necked giraffes. Explain

The nose is protected from pathogens by mucus What are the major structures of the immune system? Skin, white blood cells and lymph nodes Antibodies are produced by B cells. Diseases can be caused by viruses. After a virus is trapped by mucus in the nose, it is usually destroyed in the stomach Transplanted organs that are rejected by the new body are destroyed by killer T cells. The part of the pathogen that is remembered by the immune system is the antigen. The HIV virus attacks helper T cells. What is the function of the immune system? Protect against bacteria and viruses An organism develops active immunity as a result of producing antibodies in response to a vaccination.
