In graphite, carbon atoms are arranged in layers. Graphite has cleavage because the weak bonds between the layers break easily. Add a description wheel for fracture in your notebook.
The age of the wood would be 17,151 year's old.
Thank you for posting your question here on brainly feel free to ask as many as needed!! GOOD LUCK! I hope I helped.
Answer:
allows the recombination of genetic information
Explanation:
Crossing over is a process that occurs only in meiotic division in sexually reproducing organisms. It is the process whereby the segments of a gene are exchanged between the non-sister chromatids of homologous chromosomes.
Due to this crossing over process that occurs in prophase I of meiosis, the alleles of a chromosomes are recombined to ensure genetic diversity. Hence, according to this question, crossing over results in additional genetic variation during meiosis because it allows the recombination of genetic information.
