Answer:
c. the reshuffling of alleles in sexual reproduction.
Explanation:
During gametogenesis, meiosis occurs in reproductive cells. As a result, haploid gametes are produced. During meiosis, a process called ‘crossing over’ occurs in the pachytene stage of prophase I of meiosis. During crossing the chromosome segments are exchanged between non-sister chromatids of homologous chromosomes. Exchange of chromosome segment creates a new combination of genes or genetic recombination and produces hybrids. Thus, genetic variation occurs in all sexually reproducing organisms due to crossing over.
Answer:
Plants have cell walls provide support and gives the plant its shape. Plant cells have chloroplasts, but animal cells do not. Chloroplasts enable plants to perform photosynthesis to make food(glucose). Plant cells usually have one or more large vacuole, while animal cells have smaller vacuoles, if any are present.
