Which of the following statements about soil formation is true?

Kisachek [45]

B. Precipitation affects the rate at which nutrients are removed from soil.

Soil is known to be a loose mixture of rock fragments, water, organic materials and air that usually accommodate the growth of vegetation. Thus, formation and development of soil is a dynamic process rather than static and soil is present when pre-historic animals roamed the Earth and some these animals are preserved only fossilized soils buried deep beneath our present soil.

3. What is crossing over? When does it occur during meiosis? Why did you have difficulty modeling this element of meiosis using

FrozenT [24]

Crossing over happens in Meiosis 1 only. In Prophase 1 a cells chromatin (chromatin = chromosomes that have not condensed yet) condense and pair up forming homologous chromosomes (paired = XX (2 chromosomes together)). When this happens segments/ alleles of the chromosomes pairing up swap over. This creates genetic diversity as each chromosome is different, it has parts from its pair. This leaves every chromosome unique and individual.

I hope this helps, sorry some of the vocab is rather technical. By the way I would suggest watching the 'Crash Course: Meiosis' on YouTube, this really helped me when I was learning this topic. :D
