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.
Answer: Each air sac is surrounded by a network of fine blood vessels (capillaries). The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell.
In my own words
Each air sac is encircled by an organization of fine veins (vessels). The oxygen in breathed in air goes over the slim coating of the air sacs and into the veins. This is known as dissemination. The oxygen in the blood is then hefted around the body in the circulation system, arriving at each cell.
A polymorphic trait
I guess that's the closest I can get to answering because you didn't add enough details.
Mitosis is necessary for cellular repair and growth of cell tissues in organisms. Without this an organism will not be able to reproduce and heal itself. This is the process in which the cell divides to create new cells that are supported through the different phases of cellular division.
