Apair-rule gene in drosophila called runt controls nervous system formation. in the mouse, runt controls blood cell formation and genital structures. in humans, the analog of runt, when mutated, causes children to lack collar bones, and the opening at the top of the skull fails to close. what kind of experiment could tell you whether these genes are conserved in function?

Osmosis is often viewed incorrectly as a process driven directly by differences in solute concentration across a selectively permeable membrane. what really drives osmosis? view available hint(s)osmosis is often viewed incorrectly as a process driven directly by differences in solute concentration across a selectively permeable membrane. what really drives osmosis? the first law of thermodynamicsthe difference in the height of water columns on either side of a selectively permeable membranethe difference in water concentration across a selectively permeable membranethe difference in sugar or ion concentration across a selectively permeable membrane
