Well the soil classification is usually done on the basis of particle sizes and composition of soil.
<span>Clay </span>usually consists of particles less than 0.075 mm in size. It is a sticky soil and shows great changes in volume with variation in its water contact. It also shows considerable strength when air dried.
<span>Silt </span>has larger particles than clay and are mainly inorganic in nature. The particle size is less than 0.075mm and exhibits slightly plastic or non plastic behaviour.
Humus is soil consisting of dead and decaying organic matter. It is mainly organic in content but some inorganic particles may be mixed in it. The top soil in a tropical forest may be considered as humus.
6)active immunity occurs when the person is exposed to a live pathogen and passive immunity<span> can occur naturally.
7) you can buy bacteria killing soap and keep your house bacteria free. wipe down everything that hands touch everyday.

The answer is CNS depression.
Reduced activity in the brain can be caused by chemical agents such as opioids, ethanol,
benzodiazepines, ethanol, and anticonvulsants. Metabolic issues such as hypoglycemia can also cause CNS depression or
accidental inhalation of chemicals such as isopropyl alcohol, or butanol.
