Half life is the time taken by a radioactive isotope to decay by half of its original mass. In this case the half life of carbon-14 is 5500 years.
The original mass is 30 g and the new mass is 3.75 g.
New mass = Original mass × (1/2)^n, where n is the number of half lives;
3.75 = 30 × (1/2)^n
1/8 = (1/2)^n
n = 3
Thus, the time taken will be; 3 × 5500 = 16500 years.
<span>The male's feathers do not get longer and longer each generation because they would reach a point in which the feathers would hinder their survival. If the females preferred feather trains that would help males fly, then males would likely have much shorter feather trains.</span>
So the original weight is 175 pounds, and the after weight is 161 pounds. so you can subtract 175 by 161, and then divide it by 175 pounds. finally times it by 100, you will get 8%
Answer:
a. Determine the allele frequencies of:
- f(T) = 0.485 ≅ 0.48
-
f(t) = 0.515 ≅ 0.52
b. Determine the genotype frequencies of the exposed generation
-
F (TT) = 0.21
- F (Tt) = 0.55
- F (tt) = 0.24
the genotype frequencies of the next generation
-
F(TT) = 0.23
- F(Tt) = 0.5
- F(tt) = 0.27
