You have
1
s
, and oftentimes with wavelength, you want to convert to
nm
which is UV-Vis range (
200~700 nm
), and is often of spectral interest.
What you want to do is:

freezing
During freezing, the temperature of a substance remains constant while the particles in the liquid form a crystalline solid. Because particles in a liquid have more energy than particles in a solid, energy is released during freezing. This energy is released into the surroundings.

Think about it like this. The boat is going 15 faster than the river, and the river is going 3 faster than the bank, so the boat is going 18 faster than the river bank
Answer:
creates the necessary male and female gametes
creates gametes with one set of chromosomes
Explanation:
Meiosis is a type of cell division employed by sexually-reproducing organisms. It produces four genetically different daughter cells that have their chromosome number reduced by half i.e. from diploid (2n) to haploid (n). Meiosis is the process whereby organisms produce their necessary gametes needed for sexual reproduction.
Male organism produces haploid male gametes(n) while female organisms produce haploid female gametes (n). These gametes contain one set of chromosome (haploid) because they have to unite in a process called FERTILIZATION. When they do, they form a diloid zygote (2n), which has the same number of chromosomes as each parent cell. That is n+n= 2n.
