Answer:
its a i just took the test
Explanation:
Answer:
D) the steady, clocklike decay of certain radioactive isotopes over time.
Explanation:
Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
For example, when rocks are formed, such as igneous rocks (formed when molten rocks cools), certain radioactive atoms are trapped inside the rocks during this formation process. Then these radioactive atoms decay over time.
The age of the rock can be estimated by comparing the occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
From the options;
A) this is about the formation of the radioactive molecules and not about radiometric dating
B) this is radiocarbon dating (cabon dating/carbon-14 dating)
C) the <em>assumption </em>is wrong since the radioactive isotopes decays not accumulate.
D) the corect option as I explained earlier.
Answer:
A
Explanation:
Subsequent boundaries are boundaries that were there before a place was established.
Example: Berlin and the wall of Berlin.

Redistricting is the process by which new congressional and state legislative district boundaries are drawn. All United States Representatives and state legislators are elected from political divisions called districts. District lines are redrawn every 10 years following completion of the United States census. The federal government stipulates that districts must have nearly equal populations and must not discriminate on the basis of race or ethnicity.[1]
See the sections below for further information on the following topics:
Background: This section summarizes federal requirements for redistricting at both the congressional and state legislative levels. In addition, recent court decisions affecting redistricting policy are summarized.
Methods: This section provides details about the various redistricting processes used in the states.
Competitiveness: This section summarizes some of the arguments about the impact of redistricting on electoral competitiveness. Margin-of-victory and competitiveness data for congressional and state legislative elections is provided for informational purposes.
Majority-minority districts: This section summarizes the legal basis for the creation of majority-minority districts and details some of the arguments surrounding the practice.
Answer:
Molecule
Explanation:
A molecule is a term that refers to the smallest unit of a molecular compound with the properties of the compounds.
Molecules are like what atoms are to elements.
Every molecule of a compound possess the unique characteristics of the compound thereby typifying it.
The term molecule is often used to denote a covalent compound with a discrete or separate unit.
