Group 13-17 contains metalloids. Boron, Silicon germanium, Arsenic, Antimony, Tellurium and Polonium are considered metalloids. They have properties of both metal and non metal. Some of the element are good semi-conductors .
A larger, biologically active protein complex is created when two or more protein subunits come together to form a quaternary structure.
A protein's quaternary structure is formed when several protein chains or subunits come together in a compact configuration. There are separate primary, secondary, and tertiary structures for each of the subunits. Hydrogen bonds and van der Waals forces between nonpolar side chains hold the subunits together.
For a quaternary structure to function as a whole, the subunits must be arranged in a particular way. Any change to the subunits' structure or how they are linked results in noticeable adjustments in biological activity.

Explanation: The reason why many scientist, and well informed people say "The History of planet earth is full of change", is because that planet earth has colliding continents, and such beings of evolution right now we think we are the only living BEINGS in the universe, so the reason why The history of planet earth is full of change is colliding continents one day New York will be with Europe, and new governments will start forming, and sooner than later humans will start to evolve onto what is "The New world"
One parent with A and another with B can produce a child with A, B, AB or O blood types.
If one parent has A and another has AB, they can either produce a child with A, B or AB blood types.
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.
