Answer:
Carbon dioxide (CO2)
Explanation:
Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2018, CO2 accounted for about 81.3 percent of all U.S. greenhouse gas emissions from human activities.
A vertebrate-animal embryo gives rise to the centrum. The centrum is a bone that is part of the vertebral column. It is the hollow space within the vertebra that protects and contains the spinal cord. Within this hollow area are several nerves that send impulses to the brain enabling the organism to function and be at its homeostasis.
The availability of carbon dioxide also affects the distribution of living organisms.
<h3>How do oxygen and carbon dioxide exchange in the environment?</h3>
Animals inhale oxygen which plays a key role in their metabolism and exhales carbon dioxide in the environment which is taken up by the plants for photosynthesis to produce glucose and oxygen.
The availability of oxygen determines the animals' distribution while the availability of carbon dioxide estimated the plant's distribution along with the environment.
Therefore, it is well described above.
