Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.

Atree root breaking a rock into smaller fragments is an example of both and mechanical weathering. when rocks are exposed to heat, they which can contribute to thermal stress. when harmful gases, such as sulfur dioxide and nitrogen oxide, react with water in the atmosphere, they can produce the agent of erosion involved in stream erosion is when the ground is so saturated that it can't absorb rainfall or when rain falls so quickly that the ground can't absorb the water, forms. a/an is a huge, heavy, moving body of ice that picks up rocks and sand and erodes the ground beneath it as these materials scrape across it. hot arid climates are prone to erosion by rows of trees and shrubs planted to protect fields from wind erosion are known as

According to the rna world hypothesis, rna acted as the genetic material and catalyzed reactions in ancient cells. what conclusion can you draw from this? a. this implies that dna and proteins aren't essential in cells today. b. this implies that rna can catalyze any chemical reaction that enzymes catalyze. c. this implies that if a cell has a problem with its dna, its rna can compensate for the damaged dna. d. this implies that dna and proteins evolved after rna.
