Question: By studying a large population of sego lilies (calochortus nuttallii) on the side of kinport peak, your colleague is interested in knowing the degree to which global climate change is affecting natural populations in Idaho. Her hypothesis is that a rare drought tolerant variant(genotype dd) might be increasing in frequency over heterzygotes (Dd) or homozygotes for the wild type allele (DD). You use molecular techniques to genotype a sampling of sego lilies, finding 130DD, 50Dd, and 10 dd. Test for HW equilibrium and draw conclusions about evolutionary forces acting on the population.Question: Your colleague also collected plants from higher up kinport peack, where conditions are harsher. You again genotype a sampling of sego lilies, finding 125 DD, 55Dd, 20 dd. Teast for HW equilibrium and draw conclusions about evolutionary forces acting on the population. Contrast your results with question 1.
Determining Diffusivity of Solutes in a Liquid Compute the diffusion coefficient of a protein macromolecule bovine scrum albumin (BSA) at 23degreeC.
Determine how to calculate osmolality for an electrolyte versus nonelectrolytes and molality versus osmolality.
what are three parts Cell respiration has. Where in the cell is each found, the molecule(s) that enter each, the molecules at the end of each, and the number of ATPs harvested from each.
If the centrioles are mispositioned in the cell, the functional mitotic spindle would fail to form. In this state, how will chromosome segregation be affected . Microtubules will not attach to kinetochores.
A analyzer discoveres that the correlation coefficient between the exposure to a dangerous chemical and the growth of a certain species of butterfly is -.40.
We are isolating DNA from a Marcian. THeir DNA turns out to be very very tiny, so we will use a very dense agarose gel to analyze the DNA. So, instead of the one percent agarose gels that we normally would use in lab,
2-cells vary in the amount of energy they need. One cell, a muscle cell, must generate large supplies of ATP. The other cell, a skin cell, requires very little ATP.
Dialysis patients, who will have blood withdrawn, dialyzed, then replaced, are always weighed while they enter the facility and then weighed carefully before they leave. What is the most probable explanation for this requirement.
Determine what biological function do methylases perform in bacteria? What adaptive value do they have for a bacterium?
Across between short-tailed mouse and a long-tailed mouse yields all short-tailed mice. Crosses among the F1 yield an F2 of 48 short-tailed and 22 long-tailed. Suggest the model to explain and perform a chi-square test of your results.
