Answer: he) is specified by the codons UUU and UUC, and the amino acid leucine (Leu) is specified by the codons CUU, CUC, CUA, and CUG.
Explanation:
Answer:
Option (b).
Explanation:
The frequency of alleles K and k in population are 0.6 and 0.4. The inbreeding coefficient is 0.3.
The heterozygote frequency can be calculated by the formula:
F = 
Here, K = 0.6, k= 0.4, F = 0.3 and H = approximate genotypic frequency of heterozygote Kk.
Put the values in the above formula
0.3 = 
H = 0.36 ≈ 0.34.
Thus, the approximate genotypic frequency of the heterozygote Kk is 0.34.
Hence, the correct answer is option (b).
Answer:
natural selection is animals slowly adapting to its environment
an example is giraffes, giraffes with longer necks will be able to consume more food than giraffes with shorter necks as they they can reach for the leaves on trees. over time the giraffes with shorter necks become extinct and giraffes with longer necks still remain.
A hazard is a danger or risk.
