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
<h3><u>
Answer:</u></h3>
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
<h3><u>Explanation:</u></h3>
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".
The vaccine has defending nature against smallpox. He designed the vaccine to defeat the disease of smallpox which was very common in milkmaids. 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.
The formula for density is mass over volume. In this problem the mass is 700 kg and the volume is 649 m^3. Thus, you would divide 700 by 649 to get a density approximately equal to 1.079. Hope this helped :))
Answer:
(a) Manual Dexterity and large brain size
Explanation:
In primates there cerebrum is expanded. The area of the brain that correlate with eye Hans coordination and stereoscopic vision are particularly large just like in humans
Answer:
А) The recombinant bacterium will produce human insulin using its own transcription and translation machinery.
Explanation:
Recombinant DNA technologies refer to molecular biology techniques used to create chimeric DNA sequences by using genetic recombination techniques. The resultant recombinant DNA can further be used for the production of desired gene products (proteins) both in vitro and in living organisms. DNA recombinant techniques involve the insertion of desired DNA regions into an appropriate vector such as, for example, in a plasmid that is amplified in bacteria. For this purpose, the desired DNA fragment is inserted into a plasmid vector by digesting both the target DNA and plasmid insertion sites with an appropriate restriction enzyme. Subsequently, a DNA ligase is used to join both DNA fragments from their ends. Finally, the transformed bacterial (host) cells are selected to express the desired inserted gene.
Asexual reproduction the the act of an organism producing offspring by themselves, without the assistance of another organism. Asexual reproduction has many different advantages, but the primary one would be that reproduction can occur with a single parent as opposed to two.
