Archaebacteria are single–celled organisms that live in pondsand reproduce by fission (i.e. each bacterium splits in twoidentical organisms). If you put one archaebacterium in acertain pond, it will reproduce by fission once a day; in 30days, the whole pond surface will be completely coveredby bacteria. How many days will it take to cover the wholesurface, if we initially put two bacteria in the pond?A. 30 days.B. 28 days.C. 29 days.D. It depends on the pond surface area.E. 15 days.23

The answer is B. 28 days.

Here's why:

Archaebacteria reproduce by fission, which means one bacterium splits into two. So, the number of bacteria doubles each day. If one bacterium can cover the whole pond in 30 days, two bacteria will cover the pond one day earlier because they will double to the same amount of bacteria one day sooner. So, it will take 28 days for two bacteria to cover the pond.

The answer is B. 28 days.

Here's why:

Archaebacteria reproduce by fission, which means they double their population every day. If one bacterium can cover the entire pond in 30 days, two bacteria would do it a day earlier because they would start from a population that is double of the initial population in the first scenario.

So, if we start with two bacteria, the pond would be covered in 29 days. However, since we started with two bacteria on the first day, we can consider that day as the first day of reproduction. Therefore, it would take 28 days for two bacteria to cover the pond.

The answer is B. 28 days.

Here's why:

Archaebacteria reproduce by fission, which means one bacterium splits into two. So, the number of bacteria doubles each day. If one bacterium can cover the whole pond in 30 days, two bacteria will cover the pond one day earlier because they will double to the same amount one day sooner. So, it will take 28 days for two bacteria to cover the pond.
