Base pairs are more biology but they are what make up DNA there are 4 (adenine, thymine, guanine, and cytosine) they each pair with each other (A to T and G to C).
The spherical object will float and the square object will sink to the bottom of the fluid as it has greater density. :)
Baking soda is a fine powder because when you touch it the baking soda is very soft
Given:
Half life(t^ 1/2) :30 years
A0( initial mass of the substance): 200 mg.
Now we know that
A= A0/ [2 ^ (t/√t)]
Where A is the mass that remains after t years.
A0 is the initial mass
t is the time
t^1/2 is the half life
Substituting the given values in the above equation we get
A= [200/ 2^(t/30) ] mg
Thus the mass remaining after t years is [200/ 2^(t/30) ] mg
Answer:
the discovery will always need to be tested more where if you're investigating you should already be in a more controlled environment
