Answer:
There is 1/8 of the parent C-14 left. 1/8 means that 3 half-lives have elapsed. Multiply the half-life of C14 by 3: 5,730 years x 3 = 11,460 years old. The sample is only 11,460 years old, to the claim is not valid.
Answer:
Convection currents in the earth's magma might drive plate motion .
Explanation:
Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the plates inside the planet ..
Answer: Antipararell strands
Explanation:
The feature of the DNA is antipararell strands
Continuous and discontinuous replication is as a result that the two strands in a DNA molecule runs antipararell, which means one strand run in the 5' to 3' direction, while the other is in the 3' to 5' direction.
The strand which is discontinuously synthesized is referred to as the lagging strand.
Discontinuously synthesized strand produce small DNA molecules attached to its own primer RNA called the okazaki fragments.
