Answer:

The correct answer will be option-B.

Explanation:

The information about DNA we know today form what, structure and functional aspects is the result of the contributions of the discoveries made by the scientists in the past.

The story of DNA begins with the identification of molecule by Johann Friedrich Miescher in the 1860s, identification of its monomers by Albrecht Kossel in 1881, functional role as the genetic material of the organism by the experiments of Hershey and Chase in 1928 and the double-helical model by Watson and Crick shows in 1953 and many other related discoveries by other scientists shows us that new discoveries are made on the basis of work of the other scientists which live or lived in the past.

Thus, Option-B is the correct answer.

The history of the discovery of DNA as genetic material of the organisms konwn to us today statred in 19th century when

Johann Friedrich Miescher

1860s

Chromosomes were first observed in plant cells by Swiss botanist Karl Wilhelm von Nägeli in 1842,

Felice Fontana discovered the nucleolus in eel cells in the year 1774

Hershey-Chase experiment shows that DNA

James Watson & Francis Crick suggest the first correct double-helix model of DNA structure

Describe a situation in your everyday life where you could use the scientific method. List all the steps of the scientific metho
emmainna [20.7K]

Yes, scientific method can be applied on many everyday activities to get a reasonable solution. Infact normally we are applying this method without having it in our knowledge that we are applying it.

For example: In morning we are going to office and we start the car, but it is not started.You turn the engine again and again but it simply donot works.

Observation (the state of defining a problem):

The car is not started

Hypothesis (A possible solution based on the information we already know):

The car is not started because it might be out of gas or there can be some other technical fault.  

Experiment (testing of hypothesis by applying different methods of solving problem):

You get the fuel and put it inside the car but it still donot works and car didnot start. Experiment didnot get solution.

Analyze the results of data and test another hypothesis

You call a technician and he check with the car engine tries and finds out that the engine was out of order and needs repairing.

Draw conclusion:

The engine do not works when it is out of order and it is a cause of a car not being started.

<em>Now the theory and law making part can not be applied on this case but it is a part of scientific method.</em>

Hope it helps!

If a force of 12 N is applied to an object
Varvara68 [4.7K]

Answer:

<h3>The answer is 3 kg</h3>

Explanation:

The mass of the object can be found by using the formula

m =  \frac{f}{a}  \\

f is the force

a is the acceleration

From the question we have

m =  \frac{12}{4}  \\

We have the final answer as

<h3>3 kg</h3>

Hope this helps you

If a large housefly 2.4 m away from you makes a noise of 47.0 dB, what is the noise level (in dB) of 5400 flies at that distance
dem82 [27]

Answer:

the noise level of 5400 flies is equal to 84.32 dB

Explanation:

Noise made by house flies = 47 dB from the distance of 2.4 m

to calculate the noise of 5400 flies at a distance of 2.4 m.

the intensity of noise

  10 log_{10}(\dfrac{I}{I_0}) = 47 dB

now,  I' = 5400 I₀

=     10 log_{10}(\dfrac{5400 I}{I_0})

=    10 [log_{10}[5400] +log_{10}(\dfrac{I}{I_0}))      

= 10 ( 3.732 + 4.7 )                            

= 84.32 dB                                          

hence, the noise level of 5400 flies is equal to 84.32 dB
