1. 100 per hour

2. 50 per hour

3. 200 per hour

4. 5 per hour

Q. The formula for exponetial population growth is

1. dt/dN = rN
2. dN/rN = dt
3. rN/dN = dt
4. dN/dt = rN

Q. A protozoan reproduces by binary fission. What will be the number of protozoans in its population after six generations?

1. 128
2. 24
3. 64
4. 32

Q. A population will not exhibit an exponential growth model when there is

1. limited food supply
2. unlimited space
3. no predation pressure
4. no adverse weather conditions

Q. A tiny $Paramecium$ starting with just one individual and through binary fission, doubling in numbers every day, and imagine what a mind boggling population size it would reach in 64 days (provided food and space remain unlimited).

1. dt/dN = rN
2. dN/rN = dt
3. rN/dN = dt
4. dN/dt = rN

Q. When does the growth of a population following the geometric growth model said to be zero?

Q. The logistic population growth is expressed by the equation:

1. dt/dN = rN ($\frac{K-N}{K}$)
2. dN/dt= rN ($\frac{K-N}{K}$)
3. dN/dt = rN
   
4. dN/dt= rN ($\frac{N-K}{N}$)

Q.

If a population of 50 paramecia present in a pool increases to 150 after an hour, what would be the growth rate of population?

1. 50 per hour

2. 200 per hour

3. 5 per hour

4. 100 per hour

Q. The rate of growth of a population is proportional to the number present. If the population of a city doubled in the past 25 years, and the present population is 100000, when will the city have a population of 500000?
