Answer

Brief Explanations:

Question 11:

The rock - column structure with sedimentary layers is indicative of a shallow - marine environment. Shallow - marine environments often have distinct sedimentary layering due to the deposition of sediments over time. Arctic tundra, deciduous forest, and tropical desert do not typically form such sedimentary rock columns.

Question 12:

Ferns are plants that thrive in warm and humid environments. The discovery of giant fossil ferns in Canada suggests that Canada once had a much warmer climate, as the current climate in Canada is not suitable for the growth of such ferns. The other options are not directly related to the discovery of fern fossils.

Question 13:

Lamarck proposed the Theory of acquired characteristics, which states that organisms can pass on characteristics that they have acquired during their lifetime to their offspring. The Law of independent assortment is related to Mendelian genetics, the Theory of artificial selection is related to human - directed breeding, and the Theory of relative fossil - dating is about determining the age of fossils relative to each other.

Answer:

  1. b. shallow marine
  2. a. Canada once had a much warmer climate.
  3. a. Theory of acquired characteristics
