select concerns that have been raised regarding genetically modified crops.

they may cause a loss in biodiversity.
they may not be safe for human consumption.
they may be more susceptible to herbivory by insects.
they may cause allergic reactions.

Explanation:

• Loss in biodiversity: Genetically modified (GM) crops can out - compete native plants, reducing biodiversity. For example, if a GM crop has a higher growth rate, it may take over habitats of native species.
• Safety for human consumption: There are concerns about long - term effects of consuming GM crops. Since they are a relatively new technology, the full impact on human health (such as on the digestive system, immune system etc.) over generations is not fully known.
• Allergic reactions: When new genes are introduced into crops (for GM), there is a risk that these new gene products (proteins) may act as allergens. For instance, if a gene from a known allergenic plant is used in a GM crop, it could potentially cause allergic reactions in consumers.

• Susceptibility to herbivory by insects: GM crops are often engineered to be less susceptible to herbivory. For example, Bt - corn has a gene from Bacillus thuringiensis that produces a toxin harmful to certain insect pests. So this is not a valid concern.

Answer:

• They may cause a loss in biodiversity.
• They may not be safe for human consumption.
• They may cause allergic reactions.
