In 2100 the number of people in the world is predicted to reach at least
- a. 1 billion
- b. 2.5 billion
- c. 7 billion
- d. 9.6 billion

The population of the world in 2100.
Answer to Problem 1MC
Option (d) 9.6 billion.
Explanation of Solution
Given Info: The United Nations figures out the world population from 1600 to 2100 years.
The world population is expected to increase to between 9.6 billion and 12.3 billion in 2100.
This population compared from today’s total is somewhat over 7 billion.
Conclusion:
Hence, the united nations figure the world population by using the plotting of graph between years and to the number of peoples in billions from 1600 to 2100 years. Using this data the number of people in the world is expected to reach 9.6 billion in 2100 years.
Therefore, the correct option is (d) 9.6 billion. Since other options are irrelevant to the answer.

A person is setting up a small clean room space to carry out an outreach activity to educate high school students about patterning using photolithography. They obtained a positive photoresist, a used spin coater, a high energy light lamp for exposure and ordered a plastic transparency mask with a pattern on it to reduce cost. Upon trying this set up multiple times they find that the full resist gets developed, and they are unable to transfer the pattern onto the resist. Help them troubleshoot and find out why pattern of transfer has not been successful. 5. You are given a composite…arrow_forward
