Sex ratio is defined as the number of females per 1000 males. This information is a valuable source for finding the population of women. According to 2011 Census, sex ratio is 940, which means 940 females per 1000 males in India. Although it is an upward trend as compared to 2001 census where sex ratio was 933. But is is still a matter of concern as female foeticide is still very prevalent. Although there are some states like Kerala and Union Territory like Puducherry in India have sex ratio in which females are more than males. Kerala houses a number of 1084 females to that of 1000 males

In a laboratory there are 40 fruit flies last week and during experiment 4 fruit flies died in a week. Calculate the death rate.
1 0.1 individual per fruitfly per year
2 0.36 individual per fruitfly per week
3 0.4 individual per fruitfly per week
4 0.1 individual per fruitfly per week
Explanation:
The death rate in the population during that period is \(4 / 40=0.1\) individuals per fruitfly per week.
