Answer:
In an ancestral elm species, mutations gave rise to the phenotypic trait "winged-seeds". Subsequently, selection favored elm plants with winged-seeds that diverged over time to become a separate species
Explanation:
A mutation is a genetic change in the DNA sequence. In general, mutations have a negative impact on the fitness of the individual (i.e., mutations are generally deleterious) and therefore they disappear from the population. However, there are situations where mutations are beneficial and confer an adaptive advantage, thereby increasing their frequency in the population. In this case, mutations associated with the formation of winged-seeds conferred an adaptive advantage (i.e., higher seed dispersal capacity) to individuals who had this phenotypic trait, thereby these individuals had more chances to reproduce and pass their genes to the next generation. Eventually, Elm plants with winged-seeds accumulated sufficient genetic differences to prevent interbreeding, leading to the formation of a separate species.

Answer: the answer is the last one transcription takes place on the nucleus and translation takes place in the cytoplasm
Explanation:
Answer:
Mycorrhiza is a symbiotic association in between the green plants and fungus.
The micorrhiza are located in the roots of the vascular plants. The Green plants performs the process of photosynthesis and the sugars produced are supplied to the Micorrhizas.
The fungus supplies the nutrients, water such as phosphorus that is absorbed from the soil to the plant body.
Answer:
Zoning bylaw
Explanation:
Community and housing development rules that govern such things as minimum lot size, the outside appearance and landscaping of the property, allowable secondary buildings, parking of vehicles, and other aspects of the use and appearance of the property are called zoning by law
