Using the element Nitrogen as your example, describe the characteristics that define Nitrogen as an element, what differentiates isotopes of Nitrogen from the element and how an ionic state is determined.
There are four unique properties of water that makes it so central to life. Explain, in detail, each of these four properties.
An aqueous solution is made when a substance is dissolved in water. Explain how the pH scale represents different aqueous solutions. Use specific examples in your description.
Almost no metabolic reaction is able to occur without the help of an enzyme. Explain how the structure of an enzyme and substrate function. Include a specific example in your answer.
Explain why the shape of a protein is important. Provide three examples of different shaped proteins and their functions.
The ability to taste "Wine" is controlled by a dominant allele W, while individuals homozygous for the recessive allele w, are unable to taste Wine. In a recent genetics class of 125 students, 88 were able to taste Wine, but 37 could not. Assume H..
Choose one germline mutation as your topic focus. Discuss the normal function of the gene as well as the role of the mutated gene in cancer development and/or progression and discuss the nature of the virus, the type of cancers.
Why do you think during the evolutionary process there was a correlation between brain size increasing while cecum size decreased in the omnivores?
Glycogen stored in a skeletal muscle fiber. The closure of bone epiphyseal plate is induced by the high concentration of
Linear double stranded DNA- sample LSU1- is digested with 2 restriction endonucleases (separately and together) and the following bands are observed after electrophoresis ( quantities represent length in bp): BamH1:1,9 and 13.5;EcoR1: 3, 3.5, 4, a..
a method of sequencing that is based on synthesis i.e. "sequencing-by synthesis" that does not require the separation of newly sythesized DNA/RNA strands
The ability to taste PTC is due to a single dominant allele "T". You sampled 215 biology students, and determined that 150 could detect the bitter taste of PTC and 65 could not. What is the frequency of the homozygous recessive genotype tt
