Many species of fish produce large numbers of eggs but the mortality rate is highest among the young, with relatively constant mortality thereafter as the fish age. Which of the following survivorship curves best represents this type of population?    

The allele for brown eyes (B) is found within a population at a frequency of 0.7; the allele for blue eyes (b) at a frequency of 0.3. If the conditions for Hardy-Weinberg equilibrium are satisfied, what will be the expected frequency of heterozygous (Bb) individuals?

Approximately what percentage of energy will be passed on to the next trophic level in a typical food chain?
