I don't know the process... but I do know something else. When mosquitoes bite they actually spit some of there spit in your arm. Also only female mosquitoes bite. That all I know.... sorry! Hopefully I helped a little!!
A net population decline resulting from an "excess of deaths over births".
Option: A
<u>Explanation</u>:
Demographic transition is a shift from higher to lower level of fertility and mortality.Rapid development in industrialization and urbanization in
century resulted into enormous population growth. But decline in early
century covered many reasons like consequences of two calamitous wars, where Europe suffered large population declination due to battle death and civilian causalities in World War I and II. Hence the acceleration of population growth in 19th century but downfall in 20th is also considered as balance.
Probability of an event happening=(numbers of ways it can happen) / (total numbers of outcomes)
P=probability that we are both selected
P₁=probability that I am selected and my brother is selected after.
P₂=probability that my brother is selected and I am selected afer.
P=P₁+P₂
P₁=(1/100)*(1/99)=1/9900
P₂=(1/100)*(1/99)=1/9900
P=1/9900 + 1/9900=2/9900≈0,0002≈0.02%
solution: P=2/9900≈0.02%
- Map scale refers to the ratio between distance on a map and the corresponding distance on the ground.
- So, the option that goes with it is c. Measure the distance between places.
Hope you could get an idea from here.
