So following the octet rule, carbon atom can only form a maximum of 4 bonds because, by then, it will have 8 valence electrons.
Answer:
The recombinant frequency between T and S is 18%;
The correct Sequence of genes is T-A-S
Explanation:
The table below shows the recombinant frequency between heterozygous height and nose morphology:
Tall-uptrend snout 40% Expected
Dwarf-downtrend snout 42% Expected
Dwarf-uptrend snout 9% Recombinant
Tall-uptrend snout 9% Recombinant
Sum Total 100%
To calculate the recombinant frequency; we have :
=9+9
=18%
Hence, the recombinant frequency between T and S = 18%
The determinant of the corect sequence of the genes is T-A-S
Answer:
<em>(I) Lamarckism or Theory of Inheritance of Acquired characters.</em>
This theory is based on the comparison between the contemporary species of Jean Baptiste de Lamarck's time to fossil records.
<em>(II) Darwinism or Theory of Natural Selection.</em>
Charles Darwin made an extensive study of nature for over 20 years, especially in 1831-1836 when he went on a voyage on the famous ship “H.M.S. Beagle” and explored South America, the Galapagos Islands and other islands.
<em>(III) Mutation theory of De Vries.</em>
The mutation theory of evolution was proposed by a Dutch botanist, Hugo de Vries (1848-1935 A.D.) in 1901 A.D. in his book entitled “Species and Varieties, Their Origin by Mutation”. He worked on evening primrose (Oenothera lamarckiana).
<em>(IV) Neo-Darwinism or Modern concept or Synthetic theory of evolution.</em>
The detailed studies of Lamarckism, Darwinism and Mutation theory of evolution showed that no single theory is fully satisfactory. Neo-Darwinism is a modified version of theory of Natural Selection and is a sort of reconciliation between Darwin’s and de Vries theories.
Answer:
Birds are commonly known to eat beetles, and if the birds were wiped out, beetles wouldn't have the need to be the colors that they are. They wouldn't have a reason to hide from birds and could evolve to colors that aren't for camouflage or scaring away.
Explanation:
There are so many examples for that in different areas, like biology experiment carried out in our lab recently.
