Question options:
1. developing a hypothesis to explain collected data
2. proving a theory and writing a new scientific law
3. collecting data through observation and measurement
4. observing and experimenting to test a hypothesis
Answer:
2. proving a theory and writing a new scientific law
Explanation:
Providing a theory and write a new scientific law is not a step of scientific investigation. To prove a law a theory, its take many years of research.
There are steps of scientific investigations below,
1. Make an Observation.
2. Form a Question.
3. Form a Hypothesis.
4. Conduct an Experiment.
5. Analyze the Data and
6. Draw a Conclusion.
These step of scientific investigation does not include to write a theory and scientific law.
Genetically modified organisms are those organisms in which certain gene is inserted to get the desired beneficial results.
Explanation:
A genetically modified organism is an organism or plant altered for beneficial traits which would not have been possible by the traditional mating process or recombination techniques.
Genetic engineering is the technique involved for the construction of gene of interest and inserting them in the host species for getting expressed.
Many fruitful results have come out like a tomato of long shelf life k/a flavr savr.
Apart from molecular techniques used for cloning, CRISPR is the recent innovation which had made it very simple.
The GMOs can solve the food problem of the world as Single-cell proteins and longer shelved life food.
Disease resistant plants can be formed for better yields.
Nutrition level of food can be increased.
Example of GMO are canola, corn, papaya, soy and many animals are also on the list.
