What procedures must be described in an agreement called an "assurance of compliance" with ohrp? procedures in place to ensure that the research complies with ethical principles (such as the world medical association’s declaration of helsinki). procedures in place that ensure that subjects will be protected in a manner commensurate with the common rule, including review by an independent committee comparable to an irb. procedures in place to outline how unanticipated problems will be reported to the local irb. procedures in place to outline how subjects will be randomized?

If a cell's main function is to produce proteins to be excreted, which organelles would you expect to be larger

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.

Imagine that you are searching your room for a textbook. which portion of the cortex would be most active during this search?
