Suggest one advantage and one disadvantage of<br>using a dichotomous key to identify something.​
prisoha [69]
Advantage: Dichotomous keys are very useful because they allow non-expert users to identify organisms by directing them to look at the known, important organisms. Disadvantage: Disadvantage of dichotomous keys is that if a single wrong decision is made at any juncture, a wrong identification will result. Sometimes it becomes obvious that an error has been made, and you can retrace your steps until you get back on the right track, but this is not always the case

In 2016, Sub-Saharan Africa had a doubling time of 23.3 years.
Masja [62]

The correct answer is Option B: 3%.

In 2016, Sub-Saharan Africa, doubling time is 23.3 years, thus Growth rate is 3%.

<h3>What is doubling time?</h3>
  • The doubling time is the time taken by a population to double in its size.
  • This concept is applied to population growth, inflation, resource extraction, consumption of goods, the volume of malignant tumors, and many other things that tend to grow over time.
  • There is an important relationship between the percent growth rate and its doubling time known as “the rule of 70”: to estimate the doubling time for a steadily growing quantity, simply divide the number 70 by the percentage growth rate.
  • Therefore, Growth rate is 70 divided by doubling time (70/ doubling time).
  • Here, Doubling time= 23.3 years.
  • Growth rate= 70/23.3= 3%
