Growth of bacteria in food products causes a need to "time-date" some products (like milk) so that shoppers will buy the product

Yuri [45]

Answer: 19,960,039.97 days

Explanation: f(t) = 200e0.002t

where, f(t) is number of bacteria in millions and t is time in days.

so, if the product cannot be eaten after the bacteria count reaches 4000, it will take:

4,000,000,000 = 200e0.002t

4,000,000,000 = 200.4004003t

therefore, t= 4,000,000,000/200.4004003 =19,960,039.97 days

that is, to say that it will take 19,960,039.97 days before the product will not be eaten again.

M + + Cl2 + KI -> KC + 12

Mama L [17]

Answer:

displacement reaction.

Explanation:

When chlorine gas is passed through a solution of potassium iodide, as a result of this reaction the products i. e. solid iodine and potassium chloride are formed. This type of reaction is called a displacement reaction because in this reaction the less reactive iodine that is attached with potassium iodide is replaced by the more reactive chlorine molecule so the displacement of atoms held so we called it displacement reaction.

Alchen [17]

Answer:

recombination frequency = 4.5% or 4.5mu

Explanation:

to calculate the frequency of recombination between these genes

we have,

recombination frequency = [ number of recombinnants/total number of offsprings) x 100

total offspring = 88 + 103 + 6 + 3

total offspring = 200

Gl ra 88............................ parent

gl Ra 103.........................parent

Gl Ra 6..................................... recombinant

gl ra 3................................................ recombinant

recombination frequency = {6+3/88 + 103 + 6 + 3} x 100

recombination frequency = 9/200 x1oo

recombination frequency = 0.045 x 100

recombination frequency = 4.5% or 4.5mu
