The answer is spontaneous mutation .
Sometimes genes, for no known reason(s), change their form in a process called spontaneous mutation.
Mutation is the actually the alteration of the nucleotide sequence of the genome of an organism, virus, or other genetic elements permanently.
Spontaneous mutation : It is a process in which gene automatically for no reason change their form.
Explanation:
Desposition of solid matter in a solution
Answer:
(e) -6.1 J/K
Explanation:
Step 1: Given data
- Heat of fusion of ice (ΔH°fus): 333.5 J/g
Step 2: Calculate the heat (Qfreezing) required to freeze 5.0 g of water
We will use the following expression.
Qfreezing = -ΔH°fus × m
Qfreezing = -333.5 J/g × 5.0 g = -1.7 × 10³ J
Step 3: Calculate the entropy change (ΔS°) at 0 °C (273.15 K) and 1 atm
We will use the following expression.
ΔS° = Qfreezing/T
ΔS° = -1.7 × 10³ J/273.15 K = -6.1 J/K
Answer:
An increase in temperature lead to more effective collisions between reactant particles
increase in the rate of a chemical reaction because the number of molecules with sufficient energy to react increases.

Answer:
Explanation:
Hello,
In this case, the by mass percent is computed as shown below:
Whereas the solute is the sugar and the solvent the water, therefore, the concentration results:
Best regards.
