Answer:
The original sunlight is a mixture of colors.
Explanation:
- The sunlight is perceived by our eyes as white because it is a mixture of seven colors - violet, indigo, blue, green, yellow, orange, and red.
- When these colors of light separate from each other and are differentially absorbed and reflected, we can see the different objects in different colors.
- The reason for the differential absorption and reflection is that the different colors have different wavelengths.
- Therefore, the barn looks red because the red light is reflected by the barn and other lights are absorbed, however, the original color of the sunlight is white.

Explanation:
A cell is the most basic level of biological organization
Meosis results into genetic variability through:
Fertilization, cross-over and independent assortment.
- In Fertilization, the process leds to genetic diversity by allowing each parent to contribute to a specific set of genes to a zygote.This process depends on meiosis to create a haploid gametes where fertilized cells restore a diploid number.
- Crossing over occurs in the prophase stage of the meiosis 1 where a double chromatid homologous pairs of chromosomes exchange chromosome segments as they cross over each other.This makes genes from each parent to mix and result into a different genetic composition.
- Chromatid assortment happens in meosis 11 where sister chromatids separate and move to the daughter cells.The crossover that occursin meosis 1 results to non-identical chromatids in meosis 11 chromosome.
