Suppose that the extracellular concentration of Cl– is 123 mM and the intracellular concentrationis 4 mM. The membrane electrical potential (?V) is 0.06 V, inside negative relative to outside.At 298 K, for transport of Cl– ions from the outside into the cell:
1) Calculate the electrical potential term of ? Gtransport for transport of Cl– ions into the cell, the term reflecting the electrical gradient across the membrane. Does this term favor flow of Cl– ions into the cell, or out of the cell?2) Calculate the overall ? Gtransport for flow of Cl– ions from outside into the cell. Would Cl– ions flow into the cell, or out of the cell, under conditions described in question above?
Suppose that every non sterilized individual makes exactly ten gametes. Determine the total number of gametes?
A spotted rabbit, when crossed with a solid-colored rabbit produced all spotted offspring. When these F1 rabbits were crossed among themselves they produced thirty-two spotted rabbits and ten solid colored rabbits.
If the preclinical prevalence of breast cancer increased in the screened population would you expect the positive predictive value to increase, decrease or remain unaltered? Why?
What is the distinction between autopolyploids and allopolyploids and how do genetic ratios in testcrosses and F2 progenies differ for autotetraploids and allotetraploids?
Biotechnology allows us to employ living organisms or their processes for human needs or purposes. Research how biotechnology is used today. Discuss one use of biotechnology, answering the following questions:
Develop a labeled diagram of a small section of the plasma membrane and briefly describe its structure and function.
Suppose if we had a population of 1000 individuals, how many would be feebleminded? How many would be carriers for feeblemindedness? Is mitochondrial DNA testing based on valid scientific theory?
A rancher genotypes all of her 150 head of cattle. In her herd, 25 are A1A1, 75 are A1A2, and 50 are A2A2. Assuming there is random mating, no selection, no mutation, and no new cattle are introduced into the population, what is the probability ..
