Answer: Here are the options.
A. Unknown
B. No role.
C. Fully determines.
D. Can contribute but does not fully determine.
The correct option is D.
Can contribute but does not fully determine.
Explanation:
According to research, Genes can contribute to anxiety disorder but cannot fully determine because certain chromosomal or genes are linked to panic or anxiety disorder. Scientist discovered that RBFOX1 gene may make someone more likely to develop generalized anxiety disorder which shows that anxiety disorder are linked to genes. Anxiety disorder can be inherited and it is linked to specific genes.
Anxiety disorder is a feeling and not a mental illness. They symptoms of anxiety disorder are phobias, excessive worrying, memory problems, tensed muscles, irritability, struggle to sleep e.t.c. Some environmental factors also can contributed to anxiety disorder.
Case studies do not allow for replication. So, the correct option is (b).
Case studies are investigations that compile in-depth information about a person or group. They employ a wide range of research techniques, including observations, interviews, case studies, and personality tests, to collect the data. They can frequently collect both qualitative and quantitative data thanks to this. Research can be cross-sectional or longitudinal, which lasts for a long time.
It enables a researcher to thoroughly explore a subject. Case studies are unreliable because they cannot be duplicated and hence cannot be reliability tested. Any data acquired cannot be used to make generalisations because the outcomes are specific to the time, event, setting, and individual.

Answer:
Genetically modified organisms are created by
B. Inserting pieces of DNA, which will result in pest or disease resistance in a crop.
Explanation:
A genetically modified organism (GMO) is an organism in which the genetic material has been changed using techniques of genetic engineering . Genes have been transferred within the same species, across species (creating transgenic organisms) and even across kingdoms. New genes can be introduced, or endogenous genes can be enhanced, altered or knocked out.
Creating a genetically modified organism is a long process. The gene that genetic engineers wish to insert into the host organism must be isolated and fused it with other genetic elements. A number of techniques are available for inserting the isolated gene into the host genome. Recent advancements using genome editing techniques like CRISPR-Cas9 that can be used to edit genes within organisms have made the production of GMO's much easier.
