Answer:
- law of superposition - Relative Dating
- important method for geologists - Absolute Dating, Relative Dating
- places historical events in their correct order - Relative Dating
- establishes how many years ago a given event took place - Absolute Dating
- radioactive decayused on rock strata - Absolute Dating
Explanation:
Absolute dating is an important process used by geologists. This process allows geoologists to determine the timing of a given factor in the environment. In other words, absolute dating allows a numerical age to be estimated for that factor or the age interval between factors, but without putting the factors' formation events in order. It is generally used to date chemical and physical elements present in artifacts and rocks.
Relative dating is also an important process for geologists, but it does provide a relative order of past events and does not provide a numerical age, like absolute dating. It is generally used to date rocks, surface deposits and fossils, often using the law of superposition as a basis.
Each kidney has nearly a million individual processing units called capillaries is false as the units are called nephrons.
<h3>
What are the nephrons?</h3>
Nephron, processing unit of the kidney, the shape that certainly produces urine withinside the procedure of doing away with waste and extra materials from the blood.
The nephrons paintings via a two-step procedure: the glomerulus filters your blood, and the tubule returns wanted materials for your blood and eliminates wastes. Each nephron has a glomerulus to clear out out your blood and a tubule that returns wanted materials for your blood and pulls out extra wastes.

Explanation:
Bauxite is the most common aluminum ore. Approximately 98% of primary aluminum production is based on bauxite. In the former Soviet Union, aluinite and kaolinite are also used in small proportions for aluminum production. Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals plus various mixtures of silica, iron oxide, titania, and other impurities in trace amounts. The principal aluminum hydroxide minerals found in varying proportions within bauxite are gibbsite (trihydrated) and boehmite and diaspore (both monohydrated). The content of aluminum oxide is 30–60%. Bauxite is generally extracted by open cast mining from strata, typically 4–6 m thick under a shallow covering of topsoil and vegetation (Table I).
Answer:A set of five nitrogenous bases is used in the construction of nucleotides, which in turn build up the nucleic acids like DNA and RNA. These bases are crucially important because the sequencing of them in DNA and RNA is the way information is stored.
