Need Help: Got this wrong and struggling with which is true or false.

Question

Researchers have discovered that the value of r in aphids depends on the average temperature where the population lives, suggesting that climate change could affect population growth in aphids. Interpret the model.

Drag "True" or "False" to the end of each statement.

A. The value of r increases over time in both cases. (True or False)

B. Both curves show exponential growth. (True or False)

C. Ninety days after the introduction of 10 aphids, there would be more aphids in the population with r₁ than in the population with r₂. (True or False)

D. If r₂ = 0.02, then r₁ > 0.02. (True or False)

E. The slope of the lines at 90 days is determined by rN in both cases. (True or False)

Answer 1

A. False - the value of each r stays the same the whole time, it's just a number.

B. True - these are exponential curves

C. True - at the 90 day mark, r1 is higher (about 100 aphids) than r2 (about 50 aphids).

D. True - r1 goes up faster than r2, so it will be a higher number (rate)

E. True - how much reproduction is occurring (number of organisms) is a function of the rate times the number of individuals in the population
