Select the correct answer.
both bacteria and amoeba are unicellular organisms. bacteria are considered to be prokaryotes, whereas amoebas are considered to be
eukaryotes. how will you justify this reasoning?
a.
though both are unicellular, bacteria possess a well-defined nucleus without anucleolus. amoebas possesses a nucleus with a
nucleolus, but no nuclear membrane.
b.
though both are unicellular, bacteria possess a well-defined nucleus and all essential cell organelles, whereas amoebas do not
possess a nucleus or cell organelles, except ribosomes.
ос.
though both are unicellular, bacteria doesn't possess a nucleus or cell organelles, except ribosomes, whereas amoebas
possess a well-defined nucleus and all essential cell organelles.

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.
