Describe the role of each of the four biomolecules in our cells. In a sentence or two apiece, describe the main roles of lipids, proteins, nucleic acids, and carbohydrates.
Differentiate the lock-and-key hypothesis and the induced fit model.
Cells come in an amazing variety – single-cell organisms (like bacteria), cells of the immune system, the world’s largest cell, animal cells, plant cells, Natural Killer cells, cells with XXX chromosomes, and even cells that we could make a reality TV show with, like Cell Survivor: Livin’ On The Edge (like Archaeans ). Pick a specific differentiated (liver cell, cytotoxic T-cell, neuron) or single-cell species (Yersinia pestis) and describe what the cell does.
Population size Case study. You perform a mark-recapture study to understand the population size of slender salamanders (Batrachoseps attenuates) in Arcata, California. You initially catch and mark 15 individuals. In your second sample, you catch 20 individuals, and zero of them are marked. You estimate the total population size as A. 20 individuals B. 50 individuals C. 125 individuals D. 0 individuals E. You cannot be certain without more study or a larger sample
An alien species appears on Earth and biologists studying them collect the following life history data. The aliens are very large – nearly 200 tons in weight and over 30 meters in height. Their life span is about 800 years and they take nearly 100 years to reach sexual maturity. After mating, each female carries a single offspring and continually provides food and protection for it for the rest of her life. Consequently, juvenile mortality is extremely low and most individuals survive to adulthood. How would you describe this species’ traits, in terms of r- and K-strategists? A. These traits are all in between r- and K-strategists (in the middle of the continuum, not at either extreme) B. These traits are all typical of r-strategists C. This species has an even mix of r-strategist traits and K-strategist traits D. These traits are all typical of K-strategists
You are trying to predict the future population size five years from now of a population of 500 bison that has an intrinsic growth rate of 0.10 per year, but you are not certain of the carrying capacity of the ecosystem. What is the difference in your predictions if the carrying capacity of the ecosystem is 1,500 bison compared to if the carrying capacity is 750 bison? A. One prediction is ~200 bison higher than the other prediction B. One prediction is ~50 bison higher than the other prediction C. One prediction is ~300 bison higher than the other prediction D. You predict a similar future population size with either carrying capacity E. One prediction is ~100 bison higher than the other prediction
