1. A population of wild geese has the following frequency for alleles at the alcohol dehydrogenase locus: ADH+ 0.70, ADH null 0.30. In a population of 1,000 birds, what will be the expected frequencies of each genotype (and the number of birds that have each genotype)? *null non-functional protein = 2. A major winter storm decimated to this population of wild geese reducing its number to 100 birds. Their genotypes are displayed below: Genotype +/++/null null/null Number 51 42 7 Is this an example of genetic drift? Prove this by using the C- squared statistical test where: c2 = (observed expected)²/(expected) -

Can someone help me answer non-graded bio questions pertaining to lactase I'm trying to understand it more.

The action of this enzyme found in Beano alpha-galactosidase can also according to many sources be used to remove  ____________ from the red blood cells of the B blood group and convert them to the O blood group.  Since the _________ molecules (composed of many monomers) are connnected to protein on the membrane and also the cell membrane of the red blood cell itself; therefore these molecules help create cell identity and recognition, and when the are connected to proteins they are known as  _________ , but if they are connected to the cell membrane itself they are known as ____________.  This is a good question for reviewing the structures on the cell membrane as well. The only difference between the B-blood type and the O-blood type is  ________. The following is a diagram of the differences of these molecules that determine blood type.    List of answers: disaccharid, proteins ,dehydration synthesis ,nucleotide ,amino acids ,nucleic acids ,lactose ,fructose ,sucrose ,hydrolysis…

How would I create a bar graph using the Hardy -Weinberg Equation data ?

e 1.0 0.5- 0 6. Answer the questions below about hemoglobin and myoglobin. a. Sketch and label the binding curves of Mb, Hb, and Hb below. pº₂ b. In the scenarios below for Hb, indicate what effect they would have on the binding curve and give a brief explanation? Scenario Decrease in the concentration of carbon dioxide (CO₂) Distal histidine (the histidine that aids in molecular oxygen binding) mutation to phenylalanine High heat and extreme pH changes Predict if the normal binding curve of Hb will shift right (Hbt), left (HbⓇ), completely to Mb, or no longer bind oxygen completely? Brief Explanation

Do not use Ai

1. Draw the Fisher projection of D-glucose, and from Fisher to Haworth projection of ẞ-D-glucose. Label (R) and (S) configuration for each chiral carbon Fisher projection Haworth projection

2. It is known hemoglobinopathies, whi ch arise due to mutations in one of histidines a- or B- chains binding with the iron in the heme gro up.These mutations stabilize the iron in Fes form. Some drugs (eg. sulfonamides) or chemicals( eg.anilin) also can cause methemoglobinemia. Suggest, how change the properties of Hb in these cas es. For this:1)Describe the structure and function    of Hb A as a transport protein.    2) Explain the role ofiron ions in act ive centers of Hb for the binding of O23) How many molecules of Oz can bind mutant Hb, if mutation occurs in a- subunits? 4) Why can ascorbic acid be used to tr eat of such patients.

4. PFK-1 is tightly regulated with multiple potent allosteric regulators. Name three of these regulators and explain how they influence the activity of PFK-1.
