You failed to include the picture that goes with the question.  However, the oldest fossils will be the fossils in the oldest layer, which is the lowest layer of sediment.  Sedimentary rock forms as mud and silt pile up over thousands and millions of years.  The layers of sediment harden and become rock.  Organisms that are trapped in those layers become fossils as additional layers pile on top of them, forming new layers of sediment.

Considering the formation of sedimentary rocks, the fossils in layer C are the oldest. Sedimentary rocks form in layers, with the oldest rock at the bottom. So, the fossils in layers A and B are newer than the ones in layer C. The fossils in layer A are the newest fossils.

A student wants to find out if the amount of bleach has an effect on stain removal.
Step2247 [10]

Answer:

The second option.

Explanation:

We're trying to test the amount of bleach that has an effect on the stain so that is the altered variable.

The 2nd option uses different amounts of bleach to clean the same amount of stain.

If you choose the other options, people can argue that the bigger stain would be harder to clean with one cup of bleach, whereas the small stain gets two cups or the other way around.

It's not an effective way to see if the amount of bleach has an effect on stain removal.

What is the open area where an enzyme attaches called?
arsen [322]

Answer:

The open area where the substrate is attached to an enzyme is called the active site.

Explanation:

The active site of an enzyme corresponds to the place where the tertiary structure of this molecule leaves a free space to couple the substrate and be able to catalyze a chemical reaction.

Since the enzyme-substrate complex functions as a <u>key lock system</u>, the active site has a three-dimensional configuration that only admits certain molecules as substrate, which determines its specificity.
