Explain at least two ideas involving the history of evolutionary principles BEFORE Darwin's theory of discovery of natural selection.

Answers

Answer 1

Answer:

Species are fixed and Earth itself is less than 10,000 years old.

Explanation:

One theory states that species are fixed, or permanent on the earth and no change occurs. The second theory was that Earth itself is less than 10,000 years old and no change occurs in it. These two ideas present before Darwin's theory of discovery of natural selection which is rejected after Darwin's theory because Darwin's theory is based on evidences.

B. Pillar cells, lamellae, gills, respiratory system, fish
C. Pillar cells, lamellae, gills, respiratory system, cat
D. Lamellae, gills, respiratory system, fish, pillar cells

Answers

Answer:

B

Explanation:

Cats Dont have gills so rule out C. The body has to be the end so it would be B starting from Pillar cells to fish

Biological structures are arranged based on the level of the organization. The order of organization from smallest to largest is pillar cells, lamellae, gills, respiratory system, and fish. Thus, option B is correct.

What is the level of organization?

The level of organization is the arrangement of the structures based on the level of complexity. It starts from the most simple to the most complex structures. It starts with an atom and ends in an ecosystem.

Pillar cells are the simplest level that comprises the fundamental unit made of molecules. They together make the tissues or the lamellae in the fish. The tissues or the lamellae group together to make the organ and gills.

The gills combines with the other organs to make the organ system like the respiratory system, which together with various organ system makes the fish the makes a complete organism.

Therefore, the order of the organization starts with pillar cells and ends at fish.

What is learned behavior?

Learned behaviors are those behaviors or characteristics that we learn from observing other people, learning and reading, and our experiences. It is the best type of characteristic of humans because learning just by observation is very efficient.

This behavior can not be inherited by another person because it is not in our genes. The behavior can be acquired by nature and the learning ability of a human, not inheritance. The genetic qualities are only inherited.
