Answer:
True.
Explanation:
Enkephalins and endorphins are endogenous peptides while morphine is an exogenous peptide.
Enkephalins and endorphins are powerful analgesics 18 to 500 times more than morphine. Hence, morphine is less analgesic than enkephalins and endorphins.
Enkephalins and endorphins act on the mu, kappa , delta receptors and morphine also acts on the same receptors. All of them has same effects on the body.
Hence, Enkephalins and endorphins are peptides that act like morphine.

Answer;
B. improved ecosystem health
Explanation;
-Surface mining is a method of extracting minerals near the surface of the Earth. The three most common types of surface mining are open-pit mining, strip mining, and quarrying.
-The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, and surface water by chemicals from mining processes.The environmental effects of surface mining include;
- Habitat destruction
- Soil erosion
-
Air pollution from dust particulates
-
Pollution (especially from sediments)
-
All surface mining techniques negatively affect the environment, though some methods are more damaging than others.
