You count the number of individuals (cells) in the population each day and summarize the data in this table: Day Population Size (Individuals) 45 79 2 133 You also recall the following population rate equations: No = Noert N. = No At If you wanted to calculate growth rates of the population at the end of this time interval, which values from your dataset should be plugged into these equations? Select all that apply. O t = 2 O NO = 0 O No = 45 D t = 3 O Nt = 79 O Nt = 133 Part 2 Imagine that you next calculate the instantaneous growth rate (r) in the protist population and find it is approximately 0.542. Which conclusion can you make about this protist population? O The population size is decreasing because r is less than one. The carrying capacity of the population has been reached because r is less than one. O The population size is unchanging because r is less than one. The population size is increasing because r is positive
