Answer:

A Mineral is defined as an inorganic, naturally occurring, homogenoussolid, with a definite chemical composition, and ordered (crystalline) atomic structures.

Explanation:

Inorganic: Involving neither organic life nor the products created from or by organic life.

Naturally Occurring: Must be formed by natural processes, meaning a mineral cannot be manmade, manufactured, or created in a laboratory.

Homogeneous Solid: A mineral must be chemically and physically uniform down to the atomic level.

This homogeneity means that the mineral will have absolutely predictable physical properties

including hardness, density, and streak.

Definite Chemical Composition means that all occurrences of that mineral have a chemical

composition that varies within a specific limited range and the atoms that make up the mineral must

occur in specific ratios.

Ordered Atomic structure (Crystalline): The atoms in a mineral are arranged in a systematic and

repeating pattern. Glasses such as obsidian, which are disordered solids, liquids (e.g., water,

mercury), and gases (e.g., air) do not have a crystalline structure and are therefore not minerals.

Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans true or false ?
PtichkaEL [24]

"Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans" is TRUE.

Answer: Option A

<u>Explanation: </u>

Frogs also have the excretory system with two kidneys and similar to mammals. Its function is to eliminate the nitrogen product from the blood. Frogs make large volumes of dilute urine to wipe out harmful products from the tubules of the kidneys.

Tadpoles and aquatic frogs excrete the nitrogen as ammonia, but most terrestrial adults excrete it mostly as urea which is less threatening substance. A few tree frog species with little water access excrete the still less harmful uric acid.
