question 24 (4 points)
(01.03 mc)
what macromolecules are capable of self - replication?
○ a proteins
○ b rna and dna
○ c polysaccharides
○ d fats and triglycerides
question 25 (4 points)
(01.03 mc)
the evolution from vesicles to true cells was enabled by the development of
○ a a membrane separating the cell from its environment
○ b organic molecules, such as carbohydrates and lipids
○ c self - replicating molecules, such as rna and dna
○ d inorganic molecules, such as nitrogen and oxygen

Explanation:

For Question 24: RNA and DNA are nucleic - acids that can self - replicate through processes like DNA replication and RNA transcription/translation. Proteins are synthesized based on the information from nucleic acids, polysaccharides are energy - storage or structural molecules, and fats are energy - storage molecules, none of which can self - replicate in the same way.
For Question 25: The development of a membrane separating the cell from its environment was crucial for the evolution from vesicles to true cells as it allowed for the establishment of a distinct internal environment necessary for cellular functions. Organic molecules like carbohydrates and lipids are important components but not the key factor for this evolution. Self - replicating molecules are important for heredity but not the enabling factor for this transition. Inorganic molecules like nitrogen and oxygen are needed for various cellular processes but not the key to this evolution.

Answer:

Question 24: B. RNA and DNA
Question 25: A. a membrane separating the cell from its environment
