Briefly describe the cytoskeletal structure and biological function of motile cilia why do we need to study the bending properties of single cilia?

Did lead poisoning bring down ancient Rome?

Some researchers have questioned whether lead poisoning contributed to the downfall of the Roman Empire. There are several published papers explaining the potential evidence and their importance.

You need to search different resources and discuss if this could be true or not? And why?

Assume you are studying some species of flower that comes in three different colors: red, pink, and white. You know that color is determined by a single locus with two alleles with incomplete dominance. You count 124 red flowers, 62 pink flowers, and 30 white flowers. What are the allele frequencies and is the population in Hardy-Weinberg equilibrium? Calculate the chi squared test statistic and p-value.

What is the Hardy-Weinberg principle for a gene with two alleles in a tetraploid?

Should researchers or the family “play God” and try to correct the neuronal cells that are affected in Spinal Muscular Atrophy? Discuss your views on this potential stem cell therapy and discuss the ethical questions that you think need to be considered when developing new DNA based medical treatments.

Describe how animals produce energy in aerobic and anaerobic conditions.

Is acid rain a problem for plant species and crops today? How are plants impacted by acid rain? Do a web-search and include the name of at least one specific crop in your answer. Your answer should be at least 10 sentences long. As always, include references to information sources used.

There are often several receptor subtypes for one neurotransmitter, like acetylcholine, which are distributed in different parts of the nervous system. Why might it be useful to have different receptor subtypes in specific areas? What clinical implications would it have?

Suppose the following genotypes are in a 1:1:1:1 ratio. TTDD, TtDD, ttDD, TdDd If there are a total of 160 individuals, how many of them have the genotype TdDD?

1. In a nutshell, what are the major steps performed during next generation sequencing of DNA? How do these steps differ in the Illumina platform as compared to the Roche 454 platform?

2. In a nutshell, describe the major steps performed during DNA sequencing by the Pacific Biosciences, as well as the Oxford Nanopore Sequencing Technologies.

3. In a nutshell, describe the major advantages and disadvantages of each DNA sequencing platform.

Which of the amino acids neurotransmitters would be responsible for producing an action potential and which would most likely be released to prevent an action potential from occurring? Can you think of a time when it might be helpful to have a neurotransmitter that, when it binds to the post-synaptic cell, it inhibits an action potential?

You counted 620 colonies on a plate with a dilution of 10^-2. How many cells/ml were in the original sample?

c) What would you expect your urinalysis to be like after strenuous exercise (e.g, you just completed a 10-mile run)? Specify what values you expect to have changed and why?
