Answer:
The correct option is C - Professor Scrawll applied 100 nM BurD to the cells for 24 hours, while Dr. Bogey applied 1 nM BurD to the cells for 12 hours.
Explanation:
The correct option is C - Professor Scrawll applied 100 nM BurD to the cells for 24 hours, while Dr. Bogey applied 1 nM BurD to the cells for 12 hours.
As the exotoxin, BurD is very stable and lyse the ankle cells very quickly, more concentration and more time of action should only lyse the cells. Perhaps Dr.Bogey's ankle cells were not lysed because the concentration she used was only 1nM compared to the 100nM concentration used by Dr. Scrawll, and the time period of incubation was only 12 hours compared to the 24 hours used by Dr. Scrawll.
Considering the other explanations given in the remaining options, the concentration and time of incubation used by Dr. Bogey are more than that used by Dr. Scrawll which should only have possibly lysed the cells. Moreover, contamination with bleach also should have only lysed the cells.
African fruit bats are likely involved in the spread of Ebola virus and may even be the source animal (reservoir host). Scientists continue to search for conclusive evidence of the bat's role in transmission of Ebola.
Molecule - they have a wide range of sizes and structures and perform a vast array of functions.
cell - consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids
tissue - an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function
population - same species that live in a particular geographic area at the same time
organ system - organs that work together as a biological system to perform one or more functions
ecosystem - community of living organisms in conjunction with the nonliving components of their environment
