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.
Answer:
In the given question, out of the four options
Option C. Facilitated diffusion
is correct.
Explanation:
In any hypertonic solution, flow of water is through the transporting channels known as 'aquaporins' which are embedded in the plasma membrane of the cell. Such type of transport is passive transport or passive movement of ions or molecules through a particular transmembrane protein integrated in it. This type of transport can also be referred to as passive mediated transport or commonly known as facilitated diffusion.
Answer:
A. the concept of cultural landscape
Explanation:
The adobe is a structure that was made by three tribes (Zuni, Pueblo, and Hopi) that lived in Southwest of America. The adobe is built with sun-dried earth made from sand to make strong brick-like materials, clay, water, sandstone mixture, and organic matter. Gaps were filled with much more mud between the blocks to prevent the wind, rain, and keep out bugs and other unwanted pests. The Adobe building is an example of a cultural landscape.
