I think the correct answers from the choices listed above are options B and C. The two main sources  that lead to increased genetic variation would be Gamete mutations and recombination. <span>Gametes mutations leads to change in DNA information, recombination allows mixture of genotypes.</span>

Answer:

B) Gamete mutations, C) Recombination

Explanation:

Any random changes in the DNA of gametes are called as gamete mutations. These mutations are transmitted to the next generation via gametes and thereby the genetic variations are increased.

Recombination is the production of new gene combinations. Crossing over during meiosis I of gamete formation add new gene combinations to gametes. Random fertilization of these gametes add even more genetic variations to the progeny.

Gold has a specific heat of 0.129 J/(g×°C). How many joules of heat energy are required to raise the temperature of 15 grams of
Elodia [21]

Answer:

\boxed {\boxed {\sf 121.905 \ J  }}

Explanation:

We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;

q= mc \Delta T

The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.

  • ΔT= final temperature - initial temperature
  • ΔT= 85 °C- 22°C = 63°C

Now we know all the values:

m= 15 \ g \ \\c= 0.129 \ J / (g* \textdegree C) \\\Delta T= 63 \ \textdegree C

Substitue the values into the formula.

q= (15 \ g)( 0.129 \ J / (g* \textdegree C)) ( 63 \ \textdegree C)

Multiply the first numbers together. The grams will cancel.

q= (1.935 \ J/ \textdegree C) ( 63 \ \textdegree C)

Multiply again, this time the degrees Celsius cancels.

q= 121.905 \ J

<u>121.905 Joules</u> are required.
