:
<u><em>A. Biomass decomposes via anaerobic respiration in the deep soil.</em></u>
<u><em>B. Plants on land take up carbon dioxide via photosynthesis.</em></u>
<u><em>E. Carbon is transferred from the surface ocean to the deep ocean via the “biological pump” of settling organic matter.</em></u>
<u><em /></u>

Two statements support the claim that Jenner has been given credit for starting and spreading the practice of immunization:
- Jenner became interested in the protective effects of cowpox during his apprenticeship. Here, we are told that Edward Jenner started working on ways to defend the body against diseases as early as during his apprenticeship when he was a teenager. He had been told that farm workers who had contracted cowpox were immune to the smallpox epidemic which was spreading across Europe at the time. He then started working on a vaccine containing cowpox.
- Jenner made the first step to erase smallpox. This first step was to try his new smallpox vaccine on a child in 1796. The child did not catch smallpox. In order to get recognition and validation from the authorities, Jenner administered his vaccine to 22 more people, with success.
