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.

An aromatic group is a functional group which gives a positive test in a xanthoproteic test.
Xanthoproteic is a test for protein detention. The concentrated nitric acid reacts with proteins if they are present to form yellow colour. By adding alkali it turns orange-yellow through xanthoproteic reaction. Due to a phenyl group, the hydroxyl group can make the test positive in xanthoproteic.
An aromatic group consists of six hydrocarbons with an alternating single and double bond between carbon atoms which form rings.
Garter snakes and rough-skinned newts are coevolving because adaptations in both species result directly from interactions with the other species.
Wherever these deadly newts lived with garter snakes, local snake populations developed impressive resistance to tetrodotoxin. And it prompted newts to produce more toxins, which are 10,000 times more deadly than cyanide. Seeds are involved in co-evolution games. In other words, each player modifies his body and biological composition to survive.
Resistant to the deadly toxins lurking in the harsh newt skin, garter snakes swallow you. Snakes do not eat blowfish. Fugu is a delicacy of seafood made from puffer fish meat and is famous for its toxic potential.
