Biological control agents are designed to have no negative impact on non-target organisms like plants, mammals, birds, or other insects (A).
These agents are used in ecologically sensitive areas to help maintain biodiversity (B).
Biological control agents are species-specific, targeting only the pests they are meant to control, which makes them effective without harming beneficial insects (C).
Integrated pest management (IPM) is actually one of the major benefits of biological control, contrary to the statement in option D.
Thus, D is incorrect.
Final Answer:
A, B, C
The percentage error in the measurement of mass and velocity are 3% and 4% respectively. The percentage error in the measurement of kinetic energy is:
If \( L, M, N \) are the midpoints of the sides PQ, QR, and RP of triangle \( \Delta PQR \), then \( \overline{QM} + \overline{LN} + \overline{ML} + \overline{RN} - \overline{MN} - \overline{QL} = \):
