What do you know about cell differentiation in multicellular organisms? check all of the statements that are true. proteins play a key role in cell differentiation. the external environment, specifically temperature, during the development of turtles and some other reptiles to determine the sex of hatching offspring different transcription factors are associated with the differentiation of stem cells into bone, muscle, and nerve cells. transcription factors bind to regulatory regions of a gene and affect their expression. the amount of available light or daylength to determine the patterns of gene expression that lead to flowering in some plants.

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.
