Answer:

(I) Lamarckism or Theory of Inheritance of Acquired characters.

This theory is based on the comparison between the contemporary species of Jean Baptiste de Lamarck's time to fossil records.

(II) Darwinism or Theory of Natural Selection.

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.

(III) Mutation theory of De Vries.

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).

(IV) Neo-Darwinism or Modern concept or Synthetic theory of evolution.

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.

1) a) In ONE sentence only, how is telomerase activity different from DNA polymerase activity during DNA elongation? b) In ONE s

Ipatiy [6.2K]

1. During DNA elongation, polymerase enzyme adds new, free nucleotides to the three prime end of the newly forming strand, elongating it in five prime to three prime direction while the telomerase protects the important genes at the end of the chromosome from been deleted as the DNA strand shorten during DNA elongation.

2. During DNA elongation, helicase enzyme separates the double stranded DNA into single strand by melting the hydrogen bond that holds the DNA molecule together thus enabling each strand to be copied while the telomerase acts by preventing the telomere from been deleted during elongation.

Jack has just returned after a walk in the woods. He finds several sticky weed seeds stuck to his jersey with their sharp hooks.

Flura [38]

The reason is to help in seed dispersal. Seed dispersal is the movement or transport of seeds away from the parent plant. Due to the fact that plants have very limited mobility they have to rely upon variety of dispersal; vectors to transport their seeds, including both abiotic and biotic factors. Seed dispersal is important because if seed are not dispersed, many germinating seedlings will grow very close to the parent plant which would result to competition between every one of the seedlings as well as the parent. The competition for essential growth factors such as light, space, water and nutrients.
