How is radioactive decay used to date sedimentary rocks?

Biology

Zigmanuir [339]3 years ago

The answer is; B

Different radioactive isotopes have different half-lives (which is the amount of time taken for half of the total isotopes in the material to decay). Therefore, to predict the age of a rock in radiometric dating, the initial amount of the isotopes is determined and then that of decayed ones is determined. The predictability of the half-lives of the elements is then used to determine the age of the rock/fossil.

<span>Hello to answer your question fully.

<span>B.The amounts of carbon-14 and nitrogen in sedimentary rocks are measured.</span>


Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks.

How would a change to the sequence of nucleotides in a DNA segment affect the mRNA transcribed from the DNA?​
Mama L [17]

Answer:

It would change the nucleotide sequence of the transcribed mRNA

Explanation:

During the process of transcription, a DNA template is used to synthesize a mRNA molecule. The nucleotides in the DNA molecule undergo a complementary base pairing to form the nucleotides on the mRNA. This means that the order of sequence on the DNA determines the order of sequence on the mRNA.

In a case where the nucleotide sequence of a DNA segment changes in the process of MUTATION, the sequence of nucleotides in the mRNA strand will also change. For example, if sequence: ATT on the DNA produces UAA on the mRNA, a change to AAT on the DNA will cause the mRNA sequence to change to UUA.
