Answer:

Adenine is added to the sequence.

Explanation:

DNA stands for Deoxyribonucleic acid. The DNA consists of two polynucleotide chains that bears the genetic material in all living things. The material in the DNA is coded, and consists of four chemical bases: Guanine, Adenine, Thymine and Cytosine. It is vital for inheritance.

Mutation is an alteration in the DNA sequence caused by specific chemicals or radiation. The forms of mutation that can occur in the DNA include:

-The substitution of one base pair for another.

-The removal of one or more base pairs.

-The deletion of one or more base pairs.

Which of the following correctly represents the transmutation in which a curium-242 nucleus is bombarded with an alpha particle

Alekssandra [29.7K]

<u>Answer:</u> The chemical equation is written below.

<u>Explanation:</u>

Transmutation is defined as the process in which one chemical isotope gets converted to another chemical isotope. The number of protons or neutrons in the isotope gets changed.

The chemical equation for the reaction of curium-242 nucleus with alpha particle (helium nucleus) follows:

$_{96}^{242}\textrm{Cm}+_4^2\textrm{He}\rightarrow _{98}^{245}\textrm{Cf}+_0^1\textrm{n}$

The product formed in the nuclear reaction are californium-245 nucleus and a neutron particle.

What is the ratio of Al3+ ions to S2- ions in a neutral compound?

vichka [17]

I believe the correct answer from the choices listed above is option C. The ratio of Al3+ ions to S2- ions in a neutral compound would be 2:3. When it is a neutral compound the chemical formula would be Al2S3. As you can see in every 2 ions of Al you need 3 ions of S to maintain neutrality. Hope this answers the question.
