Answer:

For the half of the radioisotopes of a certain kind to decay into more stable isotope, the amount of time required is called The Half Life.

Radiocarbon dating is typically used to date more recent objects like bones, cloth, wood, and plant fibers.

Sedimentary rocks cannot be accurately dated using isotope dating because this Rock type is formed through the sedimentation of different rocks and minerals fragment.

Using the principle of faunal succession, scientist can determine the age of rocks by the fossil flora and fauna embedded within them.

Explanation:

Carbon dating is a process which is done by the use of carbon 14 atom. It is a special type of atom which can easily help the scientist and expert to find out the age of the fossil of flora and fauna, rocks, animals, birds, etc.

Relative dating is used to determine the age of a rock, fossil, or mineral in relation to some other reference sample. Meanwhile, absolute dating is used to determine the age of a rock relative to the date of the test. Absolute uses isotopic methods, while relative dating uses stratigraphic methods.

The Paleozoic era lasted from 540 Ma to 251 Ma, so 87Rb should be used to date this fossil. 14C has a short half-life and is only accurate for dates up to 60 ka. 87Rb has a longer half-life, so it can be used to determine older dates.

Ber [7]

Answer:

2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.

Explanation:

Within the genome there are many non-coding regions that control the expression of master developmental genes such as, for example, Hox major transcription factors (TFs) in animals and MADS-box TFs in plants. These gene regulatory regions (e.g., promoters and enhancers) are generally evolutionarily conserved within certain taxonomic groups. In consequence, such non-coding regions are well known to be conserved and interact in a sequence-specific manner with major transcription factors in order to regulate developmental pathways.
