Answer:

The correct answer will be option-It would be more difficult for DNA to unzip since it would require more energy to break the bonds.

Explanation:

The DNA molecule in an organism exists as a double-stranded helical form.  These two strands of the DNA are joined via hydrogen bonds formed between the nitrogenous bases on the strands. Two hydrogen bonds are present between A and T while three hydrogen bond  between C and G.

These hydrogen bonds provide stability to the DNA as the DNA is the heredity material which has to copied and passed on to the generations .If two strands would have been joined by any other hydrogen bonds than it would take a high amount of energy to break the bonds between the bases.

Thus, the selected option is the correct answer.

A quantity of a gas has an absolute pressure of 400 kPa and an absolute temperature of 110 degrees kelvin. When the temperature
VMariaS [17]

Answer:  The new pressure of the gas is (A) 854.46 kPa.

The pressure of a given mass of gas at the absolute temperature 110 degrees K is 400 kPa.

The temperature is raised to 235 degrees K  with constant volume.

Therefore,

Initial pressure P_{1}=400kPa

Initial temperature T_{1}=110K

Final temperature T_{2}=235K

Final pressureP_{2}=?

According to pressure law of gas,

\frac{P_{1} }{T_{1} }=\frac{P_{2} }{T_{2} }     ( at constant volume)P_{2}=\frac{P_{1}T_{2} }{T_{1} }

P_{2}=\frac{400X235}{110}

P_{2}=854.46kPa

Thus, the required new pressure of the gas is 854.46 kPa.
