200J
Explanation:
Given parameters:
Force on boulder = 100N
Distance moved = 2m
Unknown:
Work done = ?
Solution:
Work done on a body is the force applied to move such body in the direction of the force.
Work done = force x distance
Input the parameters in the equation:
Work done = 100 x 2 = 200Nm or 200J
The work done in lifting the boulder is 200J

<h3>Global travel and spread of certain species</h3>
Explanation:
Many pathogenic species of bacteria, virus, and other microbes are more prevalent in developing or tropical countries rather than in developed countries.
When an individual’s immune system is weak they become more susceptible to get infected and become carriers of that particular species.
The species grows, develops, and multiplies in the host’s body and when the traveler travels to his/her home country or any other place he/she can transmit the disease to others and again the species grows in numbers. Higher the rate of spread of infection higher is the increase in species.
