An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid.
Answer: Speed: the rate at which someone or something is able to move or operate.
Tavy works well and does not permanently destroy the forest as long as field sizes are small and farmers leave adequate time for re-growth. However, if farmers return to the fallow fields too quickly, as they do when human population densities increase, the soils become exhausted. And if little forest is left in between fields, then there are no parent trees to provide seeds and seedlings to restore the forest. Eventually large areas of forest are transformed into wastelands, upon which nothing can grow—neither rice nor forest. On these areas, farmers pasture a few cattle and continue to burn the grasslands each year, to provide "greener grass" for the cattle.
Answer: Most likely to narrow down soil sample matches: <u>Soil color</u>
Explanation:
Investigating soil characteristics like water content, age, and mineral composition, can be very important in the figuring out soil sample matches. Along with soil processes, which include carbonate makeup, chemical changes and changed organic matter; these factors can all be determined by looking at soil's most obvious physical property, color.
For instance, red or yellow soil shows the presence of iron oxides and dark colored soil is likely to contain higher amounts of organic matter (decayed vegetation and animal remains). Thus, soil from closely related sites should show matching characteristics, and color analysis allows for the full analysis of soil sample matches of the same profile.
Differentiation is the process that transforms developing specialized cells with different structures and functions
