Answer: The most likely oxygen classification is OBLIGATE AEROBIC ORGANISM.

Explanation: Most medically important bacteria can be grown artificially in the laboratory provided the atmospheric conditions and temperature are correct and the culture medium used contains the required nutrients.

The thioglycollate medium is used to differentiate oxygen requirements in an isolated organisms. While catalase test is used to differentiate catalase producing from non-catalase producing organisms.

Differences in the effect of oxygen on bacterial growth provide a further way of classifying bacteria:

● OBLIGATE AEROBES, which require free oxygen to grow,

● obligate anaerobes, which are unable to grow in free oxygen,

● facultative anaerobes, which can grow in conditions in which oxygen is present or absent,

● microaerophiles which grow best in conditions of reduced oxygen concentration.

The most likely oxygen classification is OBLIGATE AEROBIC ORGANISM because from the result of the test carried out on the isolated organisms,

--> The organism is catalase positive as it was able to breakdown hydrogen peroxide to oxygen and water( bubbling after the addition of hydrogen peroxide confirmed it as positive). Catalase is an enzyme produced by all aerobic organisms.

--> while in the thioglycollate medium the organism grew at the top of the test tube in order to absorb maximal amount of oxygen.

charle [14.2K]

Answer:

The correct answer is - biological hierarchy.

Explanation:

Biological hierarchy can be understand as the comprehension of the simplest form of the life to the most broadest and complex form of the life. It includes from the atoms which is a smallest structure and cells to the interactions of in between non living things and living things.

The broadest or highest level of the organization is biosphere in biological hierarchy in includes all other living organisms with non living things present in it. atoms to cell, tissue, organ, organ system to organism. these organisms shows interaction with each other and called populations that form communities, to ecosystem and finally biosphere.

Thus, the correct answer is - biological hierarchy.

tensa zangetsu [6.8K]

Answer:

The double membrane of the mitochondria is highly folded,and therefore wider when unfolded than that of the nucleus.This is an adaptive feature  to increase the surface area for reactions (electrochemical  gradient) by accommodating protons pumped into it by the proton motive force(PMF)  from the matrix to set up the electrochemical gradients needed to generate the energy needed by ATPase synthase enzymes for ATPs synthesis.

Required number of protons needed to be accommodated by the double membrane to generate enough energy for ATPase synthesis,therefore larger surface area is needed.

Tpy6a [65]
Bacteria is a unicellular organism which can multiply very fast by binary cell division.
To get a number of divisions required for cell division: you can use the formula: 2x^{number of generations} = number of bacteria
To get 256 bacteria:
2x^{n} = 256  (you can solve this equation by a calculator)
so:  n = 8 generations

With this formula the first bacteria is taken into consideration since 1 bacteria gives two, then the two give four, then eight, 16...
