The initial size of the cultured bacteria was around 2000 after an hour the bacteria count turned to 16000 with the value of n = 8000.

Given:

n = 1000 e^ (kt)

note when t = 0,

e^kt = e^0 = 1

1000*1 ar t = 0

Stepwise solution,

4000/1000 = 4 = e^(k*1)

or

e^k = 4

k = In 4 = 1.386

when n = 1000,

n = 1000 e^(!.386 t)

t = 1.5

n = 1000 e^(2.079)

n = 8000

Hence, the correct answer is (n=4000)

Mila [183]
<h3>Steps in order fro the formation process of urine</h3>

3) Blood enters the kidneys through  the renal artery and branches to  reach the glomerulus.

1) Nephron tubules secrete waste products into collecting tubules.

4) The filtrate travels through the renal  tubule and useful substances are  reabsorbed into the blood.

2) Pressure of the blood forces water and dissolved substances through   capillaries and into the Bowman's capsule.

<h3>Explanation</h3>

The Glomerulus filters water and other substances from the bloodstream. According to the requirement of the body, reabsorption moves nutrients and water back into the bloodstream. Urine actually is made up of 95% of water and the other nutrients are waste ions and hydrogen ions.
