d. gene expression

what is a potential environmental concern related to the widespread use of genetically modified crops?
a. improved nutritional content
b. loss of biodiversity
c. enhanced pest resistance
d. increased crop yields

what genetic modification technology faces scrutiny over potential environmental impacts and concerns about long-term health effects in agriculture?
a. gene expression
b. gmos
c. genetic testing
d. crispr-cas9

Explanation:

First Question:

To solve this, we analyze each option:

• Option a: Gene editing is about altering genes, not creating identical copies.
• Option b: Cloning is defined as creating genetically identical copies of an organism, which matches the description.
• Option c: Genetic modification involves changing an organism's genes, not creating identical copies.
• Option d: Gene expression is about how genes are expressed, not about creating copies.

We analyze each option to find an environmental concern:

• Option a: Improved nutritional content is a benefit, not a concern.
• Option b: Loss of biodiversity can occur due to widespread use of genetically modified crops (e.g., if they outcompete native species), which is an environmental concern.
• Option c: Enhanced pest resistance is a benefit, not a concern.
• Option d: Increased crop yields is a benefit, not a concern.

We analyze each option:

• Option a: Gene expression is a biological process, not a technology for modification.
• Option b: GMOs (Genetically Modified Organisms) are the result of genetic modification technology and face scrutiny over environmental impacts and long - term health effects in agriculture.
• Option c: Genetic testing is for detecting genetic traits, not for modification in agriculture.
• Option d: CRISPR - Cas9 is a gene - editing tool, but GMOs as a broader category of genetically modified organisms in agriculture face more widespread scrutiny regarding these specific concerns.

Answer:

b. Cloning
