In a laboratory there are 40 fruitflies last week and during experiment 4 fruitflies died in a week. Calculate the death rate.

A

0.1 individual per fruitfly per year

B

0.36 individual per fruitfly per week

C

0.4 individual per fruitfly per week

D

0.1 individual per fruitfly per week

Text Solution

Verified by Experts

The correct Answer is:
D
Rate = `("Change in population")/("Original population")=(40-36)/40`
`=4/40=0.1` individual per fruitfly per week.

Average rate of reaction : From the concentrations of R at different times given below, calculate the average rate of the reaction : R rarr P During different intervals of time {:(t//s,0,5,10,20,30),(10^(3)xx[R]//mol L^(-1),160,80,40,10,2.5):} Strategy : Determine the difference in concentration, Delta[R] over different intervals of time. Divide Delta[R] by Delta t to determine the average reaction rate.
