Write at least a 2 paragraph answer. brianlist to whoever writes two-paragraph for both answer — Identify one trait of a plant that could be changed by selective breeding.

— Explain how the change you describe would make the plant more useful.

Explanation:

About 10,00 years ago, ancient farmers in what is now Mexico took the first steps in domesticating corn when they simply chose which kernels (seeds) to plant. These farmers noticed that not all plants were the same. Some plants may have grown larger than others, or maybe some kernels tasted better or were easier to grind. The farmers saved kernels from plants with desirable characteristics and planted them for the next season's harvest. This process is a example of selective breeding. Corn cobs became larger over time, with more rows of kernels, eventually taking on the form of modern corn.

This makes the plant more useful because corn is the primary U.S. feed grain, accounting for more than 95 percent of total feed grain production and use. More than 90 million acres of land are planted to corn, with the majority of the crop grown in the Heartland region. Most of the crop is used as the main energy ingredient in livestock feed. In conclusion, more corn will help the environment, crops and living beings.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
