Acell with internal osmolarity of 300 mosm is placed in a solution that is 300 mosm. the cell swells and bursts. which of the following statements is true? (1 point) water moved out of the cell down its osmotic gradient. when the cell is first placed into the solution, the solutes inside the cell have the exact same chemical composition as the solutes outside the cell. the cell membrane is more permeable to the solutes that are initially outside the cell than the solutes that are initially inside the cell. there is no net movement of water into or out of the cell.

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.

The double bond between a carbon atom and two oxygen atoms (a molecule of carbon dioxide) has two characteristics. what are they? a. an ionic bond is formed between the oxygen and carbon atoms. b. four valence electrons are shared. c. two valence electrons are shared. d. valence electrons are shared between oxygen atoms.
