Before exploring some of the features of the different types of eukaryotes, we should first review some of the fundamental differences between eukaryotes and prokaryotes. The two groups of organisms differ fundamentally in the structure of their individual cells. For each of the following statements, identify whether it refers to prokaryotes, eukaryotes, or both groups. a. nuclear envelope compartmentalizes the chromosomes
b. 80S ribosomes
c. has both DNA and RNA
d. plasma membrane encloses the cytoplasm

Answer: the dna polymerase checks for errors in dna to prevent replication mistakes.
i hope this !

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
