Assume that after washing your hands, you leave ten bacteria cells on a new bar of soap. You then decide to do a plate count of the soap after it was left in the soap dish for 24 hours. You dilute 1g of the soap 1:106 and plate it on standard plate count agar. After 24 hours of incubation, there are 168 colonies. How many bacteria were on the soap? How did they get there?
bushels per acre. He counts 22 ears in 1/1000 of an acre. He determines that each ear has about 700 kernels on average. He also knows that a bushel contains about 90 000 kernels on average. What is the farmer’s estimate of yield in bushels/acre?

Select the statement that is true concerning primary teeth. A) There are 20 primary teeth, and by 24 months of age most children have all 20. B) There are 24 primary teeth, and no new primary teeth appear after 13 months. C) There are 27 primary teeth, and the molars are permanent. D) There are 32 primary teeth, and most children lose these teeth due to decay because they are never very strong.

Biological recognition is important in many processes at the molecular, cellular, and organismal levels. Select three of the following, and for each of the three that you have chosen, explain how the process of recognition occurs and give an example. a. Organisms recognize others as members of their own species. b. Neurotransmitters are recognized in the synapse. c. Antigens trigger antibody responses. d. Nucleic acids are complementary. e. Target cells respond to specific hormones
Part I: Genetics – From Genes to Proteins, Mutations (Chapter 11-12) Overview: Genetic information in DNA is transcribed to RNA and then translated into the amino acid sequence of a Protein. A) Step 1 – Transcription: During the process of transcription, the information in the DNA codons of a gene is transcribed into RNA. Suppose that gene X has the DNA base sequence 3’-TACCCTTTAGTAGCCACT-5’. Question: What would be the base sequence of RNA after transcription occurs? (In this particular example, assume that the RNA product does not require processing to become mRNA. In other words, the transcribed RNA becomes the mRNA sequence.) Place your answer in the Graphic Organizer. B) Step 2 – Translation: During protein synthesis at the ribosome, the base sequence of the mRNA codons is translated to the amino acid sequence of a protein. Question: Using the mRNA that you just transcribed, use the genetic code table to determine the resulting amino acid sequence. Place your answer in the graphic organizer. Also submit the answer to these questions, using the Graphic Organizer: •What is the significance of the first and last codons? •What meaning do these codons have for protein synthesis? C) Mutations: A mutation is defined as a change in the base sequence of DNA. This may occur as a “mistake” in DNA replication, for example. Suppose that during DNA replication, two mutant DNA sequences are produced as shown following. For the 2 mutated DNA sequences, you will investigate how these changes might affect the sequence of amino acids in a protein. Question: For each of the two, you will need to first transcribe the mRNA, and then use the genetic code table to determine the amino acid sequence. •Submit these transcriptions and amino acid sequences as part of your assignment in the Graphic Organizer. •In addition, state whether the protein sequence changes for each. •Also, explain why a change in amino acid sequence might affect protein function. Here is the original sequence, followed by two mutated sequences, 1 and 2: Original sequence 3′- TACCCTTTAGTAGCCACT-5’ Mutated sequence 1) 3’-TACGCTTTAGTAGCCATT-5′ Mutated sequence 2) 3’-TAACCTTTACTAGGCACT-5’ Part II: Inheritance of Traits or Genetic Disorders (Chapter 10) Bob and Sally recently married. Upon deciding to plan a family, both Sally and Bob find out that they are both heterozygous for cystic fibrosis, but neither of them has symptoms of the disorder. Set up and complete a Punnett Square for cystic fibrosis for this couple, adapting the Punnett Square in the Graphic Organizer as needed. When doing the Punnett Square, C = normal allele; and c = allele for cystic fibrosis. Questions: Based on the Punnett square, calculate chances (percentages) for the following: •for having a healthy child (not a carrier) •a child that is a carrier for the cystic fibrosis trait •a child with cystic fibrosis Be sure to submit these percentages as part of your assignment. Part III: Cell division, sexual reproduction and genetic variability (Chapter 19) Eukaryotic cells can divide by mitosis or meiosis. In humans, mitosis produces new cells for growth and repair; meiosis produces sex cells (gametes) called sperm and eggs. Although mutations are the ultimate source of genetic variability, both meiosis and sexual reproduction also can contribute to new genetic combinations in offspring. Question: How do both meiosis and sexual reproduction (fertilization) produce offspring that differ genetically from the parents? Be sure to talk about steps in meiosis that increase variability as well as the process of fertilization

An organism is discovered that consumes a considerable amount of sugar, yet does not gain much weight when denied air. Curiously, the consumption of sugar increases as air is removed from the organism’s environment, but the organism seems to thrive even in the absence of air. When returned to normal air, the organism does fine. Which of the following best describes the organism? A) It is a facultative anaerobe. B) It must use a molecule other than oxygen to accept electrons from the electron transport chain. C) It is a normal eukaryotic organism. D) It is an anaerobic organism. E) The organism obviously lacks the Krebs cycle and electron transport chain.
