Which of the following is accurate about a population exhibiting exponential growth?

A chameleon population ($N$) in a shrubland in Cyprus has an intrinsic growth rate ($r_{\max}$) of 0.38. You estimate the total population to be 550. Assuming this population has experienced uninhibited exponential growth, what was the chameleon population 3 years ago?

You’re studying 2 different populations of the same bacteria in the lab; both in the same unlimited, ideal conditions. Population-A starts with 2,000 individuals, while Population-B starts with 20,000 individuals. Assuming both populations grow exponentially, which population will have a higher population growth rate & why?

If a bacterial population starts with 100 cells and has a per capita population growth rate ($r$) of 0.1 cells per hour per cell, what would be the population size after 5 hours?

Imagine a regional population of Atlantic Bluefin Tuna has an annual intrinsic growth rate ($r$) of 0.45. Their population ($N$) at the beginning of year 1 is 1,500. Calculate the regional population of Atlantic Bluefin Tuna at the end of year 1.
