Ques: Q: What is the type of reproduction where part of the parent plant is used to generate a new plant? Read this paragraph and choose the correct option from the provided answers: 32.3 Asexual Reproduction Many plants reproduce asexually as well as sexually. In asexual reproduction, part of the parent plant is used to generate a new plant. Grafting, layering, and micropropagation are some methods used for artificial asexual reproduction. The new plant is genetically identical to the parent plant from which the stock has been taken. Asexually reproducing plants thrive well in stable environments. Plants have different life spans, dependent on species, genotype, and environmental conditions. Parts of the plant, such as regions containing meristematic tissue, continue to grow, while other parts experience programmed cell death. Leaves that are no longer photosynthetically active are shed from the plant as part of senescence, and the nutrients from these leaves are recycled by the plant. Other factors, including the presence of hormones, are known to play a role in delaying senescence. Choices: - sexual reproduction - coaxed reproduction - byproduct reproduction - asexual reproduction A:
Ans: asexual reproduction

Ques: Q: Species that have diverged from their common ancestors have greater differences in what? Read this paragraph and choose the correct option from the provided answers: Evidence from the fossil record can be combined with data from molecular clocks. A molecular clock uses DNA sequences (or the proteins they encode) to estimate relatedness among species. Molecular clocks estimate the time in geologic history when related species diverged from a common ancestor. Molecular clocks are based on the assumption that mutations accumulate through time at a steady average rate for a given region of DNA. Species that have accumulated greater differences in their DNA sequences are assumed to have diverged from their common ancestor in the more distant past. Molecular clocks based on different regions of DNA may be used together for more accuracy. Choices: - life span - cell structure - immunology - dna sequence A:
Ans:
dna sequence
