Question 3 A disease's basic reproductive rate, Ro -S BL. where S is the density of susceptible individuals, B is the transmission rate, and L is the infectious period. Which of the parameters lised to calculate Ro is being targeted by masking practices that have been implemented for COVID-19? O B. which is the rate of disease transmission between infected and susceptible individuals in the population. The parameter B accounts for both contact rates and the probability that a contact event leads to disease spread. Social distancing changes the probability that a contact event will result in transmission. Os which is the density of susceptible individuals, Social distancing decreases the density of people. O B. which is the rate of disease transmission between infected and susceptible individuals in the population. If people change their behavior across the entire population, such that there are fewer opportunities for infected people to contact susceptible people, the transmission rate…

QUESTION 2 There are two different forms of the three-spined stickleback (Gasterosteus aculeatus), one primarily found in the ocean and the other in freshwater. The oceanic morph is heavily armored and has well-defined dorsal and pelvic spines, and the freshwater morph has far reduced armor and spines. Spines and armor are related to fitness and are controlled by two different genes. Within this single species, these differences in morphology are due to a few nucleotide changes in the two genes. This provides evidence for evolution through: a. Speciation b. Common ancestry c. Macroevolution d. Microevolution
