ANTONII [103]4 years ago

Explanation:

Primordial organisms did not require oxygen for respiration as is the case with most organisms case today. These organisms were and are still mainly anaerobic. They main form of cellular respiration is glycolysis that does not utilize oxygen. Since other organisms evolved from the primordial cells, it is deduced that the early atmosphere was not mainly composed of oxygen but mainly carbon dioxide.

In today’s aerobic cells oxygen is utilized in the Krebs cycle as a proton acceptor making cellular respiration even more efficient in the production of energy. Remember that, utlimately, organisms evolve to fit into their environment.

The number of bacteria in a certain population is predicted to increase according to a continuous exponential growth model, at a
Brilliant_brown [7]

The given question is incomplete. The complete question is as follows;

The number of bacteria in a certain population is predicted to increase according to a continuous exponential growth model, at a relative rate of 16% per hour. Suppose that a sample culture has an initial population of 71 bacteria. Find the predicted population after three hours Do not round any intermediate computations, and round your answer to the nearest tenth bacteria .

Answer:

114.7

Explanation:

A (t) represent the population of the bacteria at the time t.

Since, the population grows exponentially, the population can be calculated as follows:

A (t) = Ao ×  e^{kt}

A (t) is teh final population, Ao is the initial population, e is the exponential, k is rate and t is time.

A (t) = 71  × e^{0.16\times t}

For t = 3 hours

A (t) = 71 × e^{0.16\times 3}

A (t) = 114.7.

The population of bacteria after 3 hours is 114.7.
