Scenario 2 A black widow spider is capable of producing hundreds of offspring at one time. Black Widow spiders catch their
prey using webs. The strength of the web varies by the spider that spins it. The stronger the web, the more
likely it is that the prey will not be able to escape the web. Therefore, spiders that have the ability to spin
stronger webs are more likely to catch prey, which increases their odds of surviving to reproduce.

There is genetic variation within the population due to inheritance of a mutation.
There is competition for limited resources.
Organisms that are better suited to their environment are able to survive and reproduce.
Species produce more offspring than can survive in an ecosystem.

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.

Which of the following is a good strategy when it comes to desserts

Hershey and chase confirmed that dna, not protein, was the genetic material. how do the results of their two experiments support this conclusion?
