Answer:

Half-Life is the time for a substance (U-235 in this case) to decay to 1/2 its original mass.

Since the problem is asking for the time for U-235 to decay to 1/2 its original mass (100 grams to 50 grams) then the decay time is 1 half-life, or 700 million years.

hope it helps u kindly mark as brainliest...

Define Evolution and Natural Selection
Korvikt [17]

<h3>Evolution may be defined as any net directional change or any cumulative change in the characteristics of organisms or populations over many generations—in other words, descent with modification… It explicitly includes the origin as well as the spread of alleles, variants, trait values, or character states.</h3>

<h3>Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others</h3>

leva [86]

Answer:

0.00498

Explanation:

The equilibrium frequency  can be calculated by the formula as follows:

qe = u/(u + v)

Here, qe is equilibrium frequency, u =  0.00005 =  the forward mutation rate and v is the backward mutation rate =  0.01.  

qe = 0.00005/(0.00005 + 0.01) =

qe = 0.00498.

Thus, the answer is 0.00498.
