Question

at a temperature of 20°c the common amoeba reproduces by splitting in half every 24 hours. if we start with a single amoeba how many will there be after a) 8 days b) 16 days?

Answer 1

after 8 days it become 16 and in 16 days it became 32

Answer 2

These is an exponential growth

x= ab^(t/T)

where a is the initial population, b  is the factor by which a single elements grow, and T is the time period.

x = 1*2^(t/24)

So a) x = 2^8 = 256 amoeba

b) x = 2^16 = 65536 amoeba
