How does climate change affect humans?

Effects will vary by age, gender, geography, and socioeconomic status—and so will remedies.

Power outages in extreme weather could cripple hospitals and transportation systems when we need them most.

Crop declines could lead to undernutrition, hunger, and higher food prices. More CO2 in the air could make staple crops like barley and soy less nutritious.

Occupational hazards such as risk of heatstroke will rise, especially among farmers and construction workers. Labor could shift to dawn and dusk, times when more disease-­carrying insects are out.

Hotter days, more rain, and higher humidity will produce more ticks, which spread infectious diseases like Lyme disease. Ticks could be in much of the eastern U.S. by 2080.

Hi there

I have some multiple choices:)

1. Rising greenhouse gas levels

Which lead to:

2. Temperature rise

Which leads to:

3. Higher temperatures

4. Crop failure

5. Altered weather patterns

6. Injury

7. Homelessness

8. Ocean acidification

9. Marine ecosystem shift

10. Sea level rise  

These changes (from 3–10) in turn lead to:

11. Mass migration

12. Economic disruption

13. Malnutrition

14. Social unrest

15. Aquaculture failure

16. Infectious disease spread

17. Displacement.

Hope this helps!

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
