Answer:

Radiometric dating methods

Explanation:

Absolute dating is the process of determining an age on a chronological or specified time scale in which events occurred in archaeology and geology. Absolute dating can be determined by using properties of the atoms that make up materials.

The most common method of absolute dating uses by geologists is radiometric dating methods which is based on the natural radioactive decay of certain elements such as potassium and carbon found in the rocks. By comparing the ratio of parent isotope with a known half-life to daughter product in the rock, the age of the rock can be determined.

The carbon-14 isotope is used in radiocarbon dating, but is only useful for measuring recently formed rocks in the geologic past. The decay of Potassium-40 isotope known as potassium-argon (K-Ar) method allows dating of materials that up to 1,000 billion years old.

slavikrds [6]

Answer:

The correct answer is ribosomes

Explanation:

Bacteria is a prokaryote which means that it does not have a nucleus and other membrane-bound organelles which are present in all eukaryotic cell-like plant cell and animal cell. All three cells have some common structures like cytoplasm and cell membrane.  

Apart from the cell membrane and cytoplasm ribosomes are the structure which is present plant, animal, and bacterial cell. Ribosomes are present in all these cells because it helps in the translation process to make protein in all there models.

In bacteria, transcription and translation are coupled because the nucleus is not present in them to separate them.

mixas84 [53]

Answer:

The right answer is 1 and 4

Explanation:

A hormone is a biologically active chemical substance, synthesized by a glandular cell secreted into the internal environment where it circulates, acting remotely and by blood on receptors specific to a target cell. It transmits a message in chemical form and therefore plays a role of messenger in the body.

The emitting organ thus acts at a distance on all of the target organs of the organism or of neighboring organisms of the same species, or even of symbiotic organisms whose receptors are activated in contact with specific hormones (lasting interactions).

Answer:

They are located in the same region

They all border the state of Kentucky

They are Virginia's westernmost watersheds

Explanation:

Big Sandy, Clinch-Powell and Holston watersheds are all located in Virginia.

These watersheds are located in the west region of Virginia alongside the border with the state of Kentucky

They are located next to each other and all tree connect with Kentucky.

With their area they are not the smallest nor the largest watersheds in Virginia.

Big Sandy's area is 990 sq miles, Clinch-Powell's is 1.811 sq miles, while Holston watershed's area is 1322 sq.miles
