Dendrochronology, or tree-ring dating, provides absolute dates in two different ways: directly, and by calibrating radiocarbon results. Cross-dating determines the age of undated wood by directly matching ring patterns with trees of known age.
Hope this helps ^^
I believe the correct answer is:
C. Density-independent factor
Answer:
Option-C
Explanation:
Scientists found a fossil of a fish with four limbs or legs. The fossil was estimated to be around 375 million years old.
The fossil showed the fins and scales of a fish but they also possess the bones of proto-wrist, shoulders and the elbow.
The presence of these bones can be a clue that the fish evolved the limbs to walk on the land and will later evolve into animals belonging to amphibians, reptiles and mammals. Therefore, the Tiktaalik is considered the missing link of how life evolved from water to land.
Thus, Option-C is correct.
Any mutations in DNA are forever, since DNA is the master blueprint. All mutations will be passed onto new cells through DNA replication, and all RNA made from that DNA will also have the mutation. If the mutation occurs in sperm or egg cells, those mutations will also be passed on to the organism's offspring.
