Question

Write five useful and harmful living things with its uses and causes​

Answer 1

$\huge\bold{\underline{\underline{\red{Answer}}}}$

$\tt{\purple{Useful\:to\:Living\:Things}}$

$\longrightarrow$ Human uses of living things, including animals plants, fungi, and microbes, take many forms, both practical, such as the production of food and clothing, and symbolic, as in art, mythology, and religion. The skills and practices involved are transmitted by human culture through social learning.

$\tt{\purple{Harmful\:to\:Living\:Things}}$

$\longrightarrow$ Trace essential elements such as fluorine, copper, selenium and others can be hazardous to living organisms if present at high levels. Nonessential heavy metals such as arsenic, lead, mercury, cadmium and chromium are usually toxic to organisms at much lower levels than trace essential elements.

Answer 2

Answer:

SolidState

Solid, one of the three basic states of matter, the others being liquid and gas. (Sometimes plasmas, or ionized gases, are considered a fourth state of matter.) A solid forms from liquid or gas because the energy of atoms decreases when the atoms take up a relatively ordered, three-dimensional structure.

\underline{\tt{\green{Liquid\:State}}}

LiquidState

The liquid state of matter is an intermediate phase between solid and gas. Like the particles of a solid, particles in a liquid are subject to intermolecular attraction; however, liquid particles have more space between them, so they are not fixed in position.

\underline{\tt{\green{Gaseous\:State}}}

GaseousState

Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy. The particles exert more force on the interior volume of the container.
