One of the major contributors to our understanding of vaccination was Edward Jenner. What is Jenner's contribution to the development of vaccinations? Choose the statement that best describes the work of Edward Jenner.

a) He discovered the process of passive immunization--the transfer of protective antibodies to an individual.

b) He was the first person to demonstrate that it was possible to make a vaccine against a bacterial infection.

c) Jenner developed the process of variolation, whereby he infected people with ground smallpox scabs to protect them from smallpox.

d) He demonstrated that inoculating people with crusts from cowpox lesions protected them from smallpox infection

He demonstrated that inoculating people with crusts from cowpox lesions protected them from smallpox infection is the statement which best describes about the work of Edward Jenner.

Option d

Edward Jenner was the inventor of Smallpox Vaccination. Edward Jenner was born in Berkley, England on 17 May 1749. He was the person who first used the word vaccine or Vaccination. In 1798 he invented Variolae Vaccine also known as the "Cow Pox vaccine".

His Variolous Material was very successful in defeating the infection. That's how Jenner contributed to the rise and beginning of Vaccination and end of several infectious diseases.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
