Answer:
least, most
Explanation:
Antimicrobials are substances that function by limiting the activities of microorganisms either by killing them or by inhibiting their growths.
Antimicrobials that exhibit a wide range of cellular targets are least selective of the type of cells they kill or inhibit. They are also said to have a wide spectrum of activities.
On the other hand, antimicrobials that exhibit a narrow range of cellular targets are most selective of the type of cells they kill or inhibit. They are said to have a narrow spectrum of activities.
Some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as:<u> vestigial structures</u>.
Vestigial structures are organic structures that do not appear to fulfill any important biological function in the organism that possesses them.
- These structures are preserved as an inheritance of the evolutionary process, because at some point in the history of evolution an ancestor of the current species had that structure.
- These types of structures, which can be bones, organs, structures in the skin or any other part of the body, no longer offer any meaningful function for the body.
- The presence of vestigial structures in animals is considered proof that evolution and natural selection exists.
Therefore, we can conclude that some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as vestigial structures.

Coal, oil and natural gas carbon dioxide (CO2)
Answer:
A.
Explanation:
It is A because the diagram for choice A shows correctly how cellular respiration produces energy and releases carbon dioxide and water as byproducts(CO2). And it also shows how photosynthesis release or produces oxygen gas (O2)
