A polynomial f(x) with real coefficients and of degree n has n zeros (not necessarily all different). Some or all are real zeros and appear as x-intercepts when f(x) is graphed. A - Explore real solutions of polynomial equations of the form. where n is even or odd and f is a constant.
Catalase-negative bacteria may be anaerobes, or they may be facultative anaerobes that only ferment and do not respire using oxygen as a terminal electron acceptor (ie. Streptococci). Percentage of H202 used on catalase test: 1  For routine testing of aerobes, 3% hydrogen peroxide is used.atalase-negative bacteria may be anaerobes, or they may be facultative anaerobes that only ferment and do not respire using oxygen as a terminal electron acceptor (ie.

To learn what the results mean for you, talk with your health care provider. Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found. If your test is positive or reactive, it may mean you are actively infected with HBV.o learn what the results mean for you, talk with your health care provider.
