Chemotaxis is defined as a response to a chemical gradient of attractant or repellent molecules in the bacterium's environment. if the environment contained a gradient of attractants, which bacterium would be most likely to have a net movement toward the signal? (choose the motility deep test result as your indicators.) select one: a. the motility deep has a single green line that corresponds to where you had stabbed the needle. b. the motility deep is colorless. c. the motility deep is entirely red. d. the motility deep has a single red line that corresponds to where you had stabbed the needle.

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).
