The answer is through the placenta. The placenta is formed in the uterus of the pregnant woman. Its role is in the nourishment of the fetus. The placenta provides the fetus with nutrients and removes waste. The umbilical cord connects the placenta to the fetus and it serves as the transporting passageway.
        
             
        
        
        
<span>Thymine is harder to make, but more stable. DNA needs to keep information safe for a long time, so it makes sense to use thymine. But RNA is made and used quickly, and small mistakes don’t matter as much, so the easier to make uracil does the job.</span>
        
             
        
        
        
Answer:
Exponential Growth: y = a(1 + r)x
Exponential Decay: y = a(1 - r)x
Explanation:
Remember that the original exponential formula was y = abx.
You will notice that in these new growth and decay functions, 
the b value (growth factor) has been replaced either by (1 + r) or by (1 - r).
The growth "rate" (r) is determined as b = 1 + r.
The decay "rate" (r) is determined as b = 1 - r
