Answer:symbiotic algae.
Explanation:
Answer:
In the human body, cells are the basic units of life. Groups of cells working together for a specific function form tissues. Organs are two or more tissues operating together. Even separate organs work together, forming body systems.

Answer: Most likely to narrow down soil sample matches:Soil color
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:
Presence of rare minerals or artificial debris
Explanation:
In the lesson it clearly states, "Rare minerals and rocks or artificial debris can narrow down possible soil matches." This is also in the science journal.
