Manuel is performing a scientific investigation to determine whether fertilizer A or fertilizer B is more effective at increasing the growth rate of tomato plants. Manuel measures and separates 30 tomato plants into two equal groups that are planted in identical environments. He gives one group fertilizer A, and gives the other group the same amount of fertilizer B. During the first week of the investigation, he gives the tomato plants in both groups the same amount of water. During the second week, however, he forgets to water the tomato plants being given fertilizer B, but still provides water for the tomato plants being given fertilizer A. Two weeks after planting, Manuel measures the tomato plants and discovers that the tomato plants given fertilizer A have grown much more rapidly than the tomato plants being given fertilizer B. Manuel's resultsA. are not valid because one of the variables was not controlled during week 2.

B. are valid because he controlled all of the variables in week 1.

C. are valid because he designed his experiment correctly.

D. are not valid because he should not have grown the plants in identical environments.

Answer:

are not valid because one of the variables was not controlled during week 2.

Answer:

Explanation:

The quality and strength of data collected during a scientific investigation are based on how well the experiment was designed and executed. Although Manuel's experiment was correctly designed, he forgot to water one of the tomato plant groups during the second week. This means that his results are not valid because one of the variables was not controlled during week 2.

Describe how Edward Jenner created a smallpox vaccine.

Answers

The Variola vaccine (which was also the first vaccine made in the world) came from studies carried out by the English physician Edward Jenner. He observed people who became infected by milking cows with a disease of cattle and came to the conclusion that these people were immune to smallpox. The disease, called cowpox, resembled human smallpox by the formation of pustules (lesions with pus).

In view of this observation, in 1796, Jenner inoculated the pus present in a lesion of a milker named Sarah Nelmes, who had the disease (cowpox), in an eight-year-old boy named James Phipps. Phipps acquired the infection mildly and, after ten days, was cured. Later, Jenner inoculated Phipps pus from a person with chickenpox, and the boy suffered nothing. There, the smallpox vaccine was born.

The doctor continued his experiment, repeating the process in more people. In 1798, he reported his discovery in a paper entitled "An Survey on the Causes and Effects of Smallpox Vaccine". Despite facing resistance, in a short time, his discovery was recognized and spread throughout the world. In 1799, the first vaccine institute was created in London and, in 1800, the British Navy began to adopt vaccination.
