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:
The FDA reached the conclusion that there's no food safety concerns or human health concerns and no nutritional differences between genetically engineered salmon and its conventional counterpart,” Jaffe said.
Genetically modified (GM) salmon were patented by Canadian scientists who took a gene that regulates growth hormones in Pacific Chinook salmon and a promoter—the equivalent of a genetic 'on-off' switch—from an ocean pout and introduced them into the genetic structure of an Atlantic salmon.
The correct answer is - The population decreases.
A population that doesn't have people moving out of the country, nor people moving inside its borders, as well as high mortality rate, and low birth rate, is a population that will be decreasing rapidly, and that can lead in the end to its total disappearance.
At first the population will start to age, as there will be more middle aged and old people, and much less youngsters. As the time will pass, there will be less and less people for reproduction, and on top of that the ones that do, have one to two children at maximum. The old population will die out, and the numbers will start to significantly drop of the population, as the old and middle aged population are dominating the demographic pyramid.
Area of the square garden = 30.25 square feet
Let us assume each side of the square garden = a
Then
a^2 = 30.25 square feet
a = 5.5 feet
Now
Perimeter of the square garden = 4a
= 4 * 5.5 feet
= 22 feet
So the perimeter of the garden is 22 feet.
