Different evolution theory of living organism​

Biology
1 answer:
Neporo4naja [7]3 years ago
4 0

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.

algol [13]

Answer:

Principles of Geology

Explanation:

J. Henslow gifted Darwin the first volume of Principles of Geology, written by Charles Lyell. The book explains about the old age of the earth. Accordingly, the slow rate of several geological processes suggests that the earth is very old.

Darwin read the book as the ship was crossing the Atlantic and learned about geological processes occurring over the millions of years. For example, he learned that the earth's surface was not formed by some catastrophic event.

In his book, Lyell explained the slow and gradual geological processes like erosion gave rise to the vast landscapes present on the earth's surface.

Darwin compared the time taken by geological processes to form the earth's surface and reasoned if these millions of years were enough to support the evolution of species.

True or false: single sugars are too large to be absorbed directly into the bloodstream
AleksandrR [38]

Answer:

False

Explanation:

The sugars on the basis of the number of glucose or sugar units can be categorized into two categories:

1. Simple sugars: The sugars which contain one or two sugar units called mono and disaccharides.

2. Complex sugars: The sugars which contain more than two sugar units are complex sugars.

The simple sugars like glucose, galactose are easily digested by the digestive system of the human body and easily absorbed by the cells.

Since the simple sugars or simple sugars are small in their structure compared to the complex carbohydrates therefore false is the correct answer.
