Question 4 Leave the rocks submerged in the jars for about 90 minutes. Then use a
spoon to carefully scoop the rocks from the jar labeled 0% Acid. Dry the
rocks by patting, or blotting, them with a soft rag. After the rocks are
dry, measure their mass and record it on the sticky note. Use this
format: "Final Mass: ." Place the jar with the liquid on the counter and
place the dried rocks next to the jar. Repeat this process for the other
three jars. After you have recorded the final mass for each jar, complete
this table.

Which step if the scientific method relies more heavily on newly collected data than on creativity and innovation

With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to introduce them to the idea that the cell wall can also act as a foundation to build things upon. bacterial appendages require a strong foundation that will offer the support needed to move and function in a dynamic world. for example, flagella are long, whiplike protein structures that are used by many gram-positive and gram-negative bacteria for locomotion. in order to function effectively, a flagellum must be firmly anchored to the cell wall. how will you be able to get across the idea that the peptidoglycan cell wall is strong enough to support such a mechanism? with a protein rod that passes through the cell wall and protein rings used to anchor it in the membranes, these basal bodies are the rudimentary biological motors that use atp power to spin the hook and the flagella attached to it. bacterial flagella have a biological motor that spins within the cell wall and is powered by atp. this allows the flagella to spin in a whiplike motion to propel the bacterium.
