Answer:
It is a beneficial mutation.
Explanation: Mutations are permanent changes in the nucleotide sequence of a DNA. Mutations can beneficial, neutral and harmful or deleterious. When change in the nucleotide sequence of DNA a mutation enhances the effectiveness of a protein or improves the protein function, it is said to be beneficial. When a mutation causes the synthesis of a protein which have the same amino acid as the original protein and performs the same function as the original protein, it is said to be silent or neutral. When a mutation results in the synthesis of a protein with an altered amino acid sequence and a nonfunctional protein, it is said to be harmful.
Produce energy usable by the cells of their respective organisms.
It’s gases. Gas particles are always moving around. They have no fixed position and so they have high energies. Density depends on how many particles are present, so if the gas particles move around freely there will be very less density, but if you compress them their particles will increase in number thereby increasing the density
