Answer:
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.
Answer:
Eukariotic cells are bigger and complex than bacteria. The difference between cystoskeleton of eukariotic and bacteria cells is the type of proetein in each one.
Explanation:
The cytoskeleton is composed mainly in arrays of protein filaments. Its function is to maintain the shape of the cell, maintain in place the organelles (such as mitochondria, nucleus, etc.) and the transport throughout the cell. Every cell has a cytoskeleton, eukaryotic, bacteria and archaea. Eukaryotic cells are bigger than bacteria and have more organelles in them to maintain in place, this is why cytoskeleton are bigger and complex. The bacteria are a single cell, simpler, with a few organelles, the cytoskeleton is more simple but important. The cytoskeleton is similar in both, the difference is the type of proteins in them. In bacteria are simple proteins, meanwhile, in eukaryotic are a complex protein.
