What statement best explains why meiosis produces haploid cell rather than diploid cells
Shkiper50 [21]

The right answer is Haploid cells join to form an organism that has a complete set of chromosomes.

Meiosis makes it possible to pass from a cell to 2n chromosomes to 4 cells with n chromosomes, thus ensuring the passage from the diploid phase to the haploid phase.

So from the  fertilization phase to the meiosis phase, the cells will be diploid (2n chromosomes). From the meiosis phase to the fertilization phase, it is the haploid phase (n chromosome).

Why is it incorrect to say the insulation 'keeps out the cold'
Sonja [21]
Because technically there is no such thing as cold
all that exists is heat
this is because heat is the rapid movement of particles, made by friction (to understand why you must delve into physics and some chemistry)
so, when you feel cold, it's really the absence of heat
so instead of "keeping the cold out", which makes no sense at all scientifically, insulation keeps the heat in.

as a side note
the feeling of cold is produced when you come in contact with an object (yes, air counts) that has less heat, or energy, than you do, You feel cold because heat (energy) from your body is being transferred to the environment. This ABSENCE OF HEAT in your body is why you feel cold
