A species of bird is threatened with extinction because its habitat is being destroyed by deforestation. As a research ecologist, you may have been chosen to ensure the genetic diversity of the species. In this species of bird, feathers may be white (dominant trait) or black with white
spots. In some species, beaks may be long (dominant trait) or short. A black spotted bird with a short beak mates with a white bird with a long
beak Draw a Punnett Square on a scrap sheet to answer the following questions.
What ratio represents your dihybrid of the number of offspring that will be black spotted with a long beak?
9:16
7:16

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.
