The answers is 3 because the secon C was changed to a G.

1 and 2 are incorrect because you do not have the same number of bases as the original sequence. 3 a base was change to the U, which appears in RNA not DNA.

I'm late ik but the answer is actually A-C-T-G-C-G-A-T, and trust it is right because I took the test and the answer below was wrong. But it's not like I'm good at this stuff

Refer to Animation: Kinetic and Potential Energy. Which of the factors accounts for the higher potential energy of C-C and C-H b
Andreyy89

Explanation:

The electronegativity difference in C-C and C-H atoms is quite low. This means smaller the electron cloud. This further means larger bond length that is electron's are further from the nucleus.  hence,  higher potential energy of C-C and C-H bonds.

On the contrary, C-O and H-O have large difference in electronegativity( O is high electronegative element) . This means smaller bond length. Electron's near the nucleus. Thus, lower potential energy of bonds.

On the periodic table, calcium and bromine are located in period 4. What is one difference between the two elements?
Dovator [93]

Answer:

D

Explanation:

Just look at the groups and their tendencies. Or look at their electron configurations. You will notice that calcium has 2 valence electrons and bromine has 7 valence electrons.

Halogens have the most valence electrons possible without completing a shell (8 would be needed for that)

CO_2 sublimes readily at 25°C. Which properties are usually associated with a compound that undergoes this kind of change?
antoniya [11.8K]

Explanation:

Sublimation is defined as a process in which solid state of a substance directly changes into vapor or gaseous state without undergoing liquid phase.

For example, naphthalene balls show sublimation at room temperature.

As this process does not cause any change in chemical composition of a substance. Hence, it is known as a physical process.

Similarly, when CO_{2} sublimes readily at 25^{o}C. This shows change in physical state of carbon dioxide is taking place, i.e, from solid to gaseous phase.

Thus, we can conclude that when CO_{2} sublimes readily at 25^{o}C then it means physical properties are usually associated with a compound that undergoes this kind of change.
