Explanation:
Kettlewell thought that if natural selection caused the change in moth population.
Dark moths resting on light trees were more likely to be eaten by birds then light moths.
Pseudo vacuoles are not true organelles since they are just air bubbles which do not possess tonoplast and cell sap like real vacuoles. But they do help by increasing buoyancy of cells.
Carbon 14 is a radioactive isotope of carbon
<span>Here square frequency of recessive alleles r^2 = 160/1000 = 0.16
Therefore r = 0.16
Since r + d = 1; d = 1-0.16 = 0.84</span>
Alternative splicing is the process of gene expression. It results in a single gene being able to produce multiple functional proteins. mRNA splicing includes certain exons and excludes others. This produces different mRNA strands with different base sequences, which then translates to different polypeptide chains with different codon sequences. Different polypeptide chains will then go through processing to become different proteins.
Hope this helps! :)
