Explanation:
Mutations on DNA create genetic variation and diversity on which natural selection acts upon. Mutation can be advantageous, disadvantageous or neutral. Those mutations that confer advantage are preserved in the population while those that are DISadvantageous are weeded out. This occurs because advantageous traits that give a particular advantage to individuals in the environment, however slightest, give them an increased chance of survival and passing their genes to subsequent generations.
An example is mutation that causes sickle cell-shaped blood cells. Individuals with sickle cell blood are less likely to contract malaria. Therefore in an environment where malaria is endemic, the population will have a higher allele frequency for sickle cell alleles that populations in non-endemic areas.

Involuntary and the brain, because the stem controls involuntary reactions
It’s the first one: A. the water molecules stay the same they just change phase to a gas
Nope, it actually means the exact opposite.
Solubility
the ability to be dissolved, especially in water
- Hope this helps!
Answer : The original volume of gas was, 3.0 L
Explanation :
Charles' Law : It is defined as the volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
or,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Now put all the given values in above equation, we get:
Thus, the original volume of gas was, 3.0 L
