These have to do with the Avida-ED simulation:
1. How does Avida-ED measure fitness?
2. Based on what you observed in the Population Statistics and the Organism Type
boxes during the run, what do you think accounts for changes in individual fitness
and changes in the average fitness in the population?
3. When do you think mutations arise that can confer a
selective advantage relative to the presence of a selective agent?

5.To gain entry, spikes of the SARS-CoV-2 bind to
angiotensin-converting enzyme 2 (ACE2) found in epithelial cells
especially of the respiratory and oral passageways. As such, these
cells are susceptible to infection by SARS-CoV-2. ACE2 is a protein
consisting of multiple alpha-helices that is embedded in, and
spans, the membrane. What is this type of protein called, and what
structure do the alpha helices represent?
6.Following binding of spike proteins to ACE2, SARS-CoV-2 likely
gains entry into the cell either...

How Does Evolutionary Change Occur? "I soon perceived that selection was the keystone of man's success in making useful races of animals and plants. But how selection could be applied to organisms living in a state of nature remained for some time a mystery to me." - Charles Darwin Introduction Fundamentally, evolution is the idea that the form and behaviors of a species are not fixed - that they can change over time. Before Darwin was even born, some scientists...

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
