b. Inhalants
c. Stimulants
d. Neonatal abstinence syndrome
e. Club designer drugs
f. Depressants
Explanation:
Drug abuse can be defined as the excessive use of drugs that can be harmful to the individual or to others, which is associated with social, behavioral, physical and job-related problems. Inhalants drugs (e.g., glue, cocaine) are volatile drugs whose inhalation may induce psychoactive and/or mind-altering effects. Stimulant drugs (e.g., cocaine, amphetamines) are drugs that excite body functions by accelerating the activity of the central nervous system (CNS), while depressant drugs (e.g., alcohol) slow down the CNS. Neonatal abstinence syndrome occurs when a neonate withdraws from certain drugs (usually opioid drugs which interact with opioid receptors) to which he/she was exposed before birth. Finally, designer drugs (e.g., ecstasy, ketamine, LSD) are drugs synthesized in illegal labs which are commonly known as “club drugs” because they are often used and sold in nightclubs.
The method which is best for preventing further soil erosion in an area overgrazed by cows is better land and animal management. Farmers need to limit the space that animal used as well as create sustainable grassland production for livestock animals. Methods such as permaculture and holistic management are options to reduce and possibly eliminate overgrazing — eventually soil erosion.
Carbon is found in fossil fuels such as petroleum (crude oil).
Carbon is found in soil from dead animals and decaying animals.
Carbon is found in the biosphere stored in plants and trees.
