The table below shows carbon dioxide emissions and world population data for several years between 1800 and 2004.

Year World Population
(billions) Carbon Dioxide Emissions
(metric tons carbon per year)
1800 1 100
1850 1.3 175
1900 1.7 500
1950 2.5 1800
2004 6 8000

Based on the table above, how has population growth in the recent past most likely impacted the composition of the Earth's atmosphere?
A.
The Earth's atmosphere did not contain any carbon dioxide in 1800, but it was the most common atmospheric gas in 2004.
B.
The Earth's atmosphere contained a higher level of carbon dioxide in 2004 than it did in 1800.
C.
The composition of the Earth's atmosphere did not change between 1800 and 2004.
D.
The Earth's atmosphere contained a higher level of carbon dioxide in 1800 than it did in 2004.

its D

Explanation:

i just did it and i put the wrong answer but the correct answer is D

1: the largest region of the brain is the:

  cerebrum

2. the term "psychology" literally means:

the process or procedure of the science or study of the mind.

3. the area of the brain responsible for respiration, heart rate, and smooth muscle control of our blood vessels is t

medulla oblongata

4. the structure that conducts nerve impulses to and from the brain and serves as a reflex center for some sensory information without input from the brain is the:

spinal cord

5. the three-layered membrane that covers the brain and spinal cord and literally means membrane is called the:

meninges

6. the cord-like (string-like) structures that carry bio-electrical impulses from one part of the body to another are called

nerves

7. a group of nerve cell bodies that are found outside of the spinal cord and brain are referred to as:

ganglions or ganglia (pl.) “literal meaning knot”

8. the term that means spinal cord inflammation is:

myel/itis

gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.
