Earthquakes generally increase the rate of weathering and erosion because the energy transmitted through rocks, especially, shear waves (secondary waves) will break rocks. Volcanos emit gases such as carbon dioxide and sulfur that will cause acidic precipitation. This acidic precipitation will dissolve some elements in the rocks hence weakening them and increasing the rate of erosion.
Answer:
Crossing-over occurs during meiosis
Explanation:
Mendel's principles never mentioned directly how the factors seperate, just that it happened during gamate formation, but nothing about how crossing-over occurs during meiosis.
It means that two chromosomes
have the same genes, or variations fo the
same genes at the same loci on the chromosomes. Variation
of the same gene is what makes up
alleles. Homologous chromosomes
are similar in size and structure. In
diploid organisms, each chromosome in the pair is derived from each parent.
