A scientific theory is a theory that explains the scientist's observations, whereas a scientific law is a repeated pattern in the world that we have not sought an explanation for.
Answer: Variolation
Explanation:
Variolation can be defined as the condition in which the inocolutaion of the individuals with the infectious materials, scabs or pulses from the smallpox victim.
This was introduced by the route of nasal passage or injected intravenously. The infection that developed because of this was less than normal and it provided protein against more serious disease.
Hence, the correct answer is Variolation.
GMOs may lead to the use of different herbicides or pesticides is a true statement.
Explanation:
The GMO crops leads to growth of weeds that can resist herbicides other than for which the GMO is genetically-modified. The over-usage or over-reliance on herbicide-resistant GMO (Genetically modified organisms) crops had given way to the growth of such superweeds.
The main characteristic of these superweeds is resistance to the herbicides or the weedkillers leading to infestation of farmlands by these superweeds Hence farmers need to add different herbicides or pesticides to control the growth of superweeds.
This device is called a taxon
Correct answer: Hypothesis; Theory
A hypothesis is a predictive statement that tells us the correlation between the two or more variables. It is a testable prediction about what we expect to occur in the study.
The scientific theory gives a good explanation of the natural world that is given based on the facts that are confirmed by the continuous observation and experiment
Hence, the correct answer would be ''Hypothesis; Theory''.
