Explanation: Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor (Dunn,1993).
When the core temperature rises, stars start burning helium to carbon. Hydrogen and helium are fused in a shell surrounding the core, raising the temperature.
The most prevalent method of generating energy in the cosmos is hydrogen fusion. The gravitational force is utilised to fuse hydrogen at the centres of our Sun and other stars, where it has a density more than 70 times greater than that of steel. Thus, all of the heat and light on earth comes from fusion. Helium is a chemical element with the atomic number 2 and the symbol He. The first member of the noble gas group in the periodic table, it is a colourless, odourless, tasteless, inert, monatomic gas that is not harmful.

The change or mutation in a segment of DNA after replication may lead to changes in the genotype, the traits of the organism and the proteins (option i, ii and iii).
<h3>What is a genetic mutation?</h3>
A genetic mutation is any change in the nucleotide bases of the genome of an organism that may be associated with modifications in the phenotypic traits or features of the organism if this change alters the expression of a given gene that produces a particular protein.
Mutations may be neutral when they don't show an apparent effect on the phenotype of an organism such as occur in mutations located in intergenic regions.
Therefore, with this data, we can see that a genetic mutation may alter the proteins produced by an organism which has a direct effect on the phenotype by altering the structures that it is able to synthesize.

Answer:
8,345,925 lb-f
Explanation:
We know pressure P = F/A = ρgh ⇒ F = ρghA = ρgV
F = ρgV where F = force, ρ = density of water = 1000 kg/m³ , g = acceleration due to gravity = 9.8 m/s² and V = 1 × 10⁶ gallons = 1 × 10⁶ gallons × 1m³/264.2 gallons = 3785 m³
So, F = ρgV = 1000 kg/m³ × 9.8 m/s² × 3785 m³ = 37,093,000 N
We now convert Newtons to pound-force.
1 N = 0.225 lb-f
So, F = 37,093,000 N = 37,093,000 N × 0.225 lb-f/1 N = 8,345,925 lb-f
So, the tower must be able to withstand 8,345,925 lb-f
A. the medium
For refraction to occur, there has to be change from one medium to another. For example rays of light would refract as the travel from air to water.
