up-to-date Wth security updates fixes, and improvements, choose Check ior Updates: BACKGROUND: Many molecules and even single atom ions can't diffuse easily through the cell membrane. How do they get into and out of cells? Until now you have only observed oxygen and carbon dioxide diffusing through a cell membrane_ The way those two molecules directly pass through the cell membrane is actually quite uncommon: Most molecules are unable to pass through the membrane, So some kind of hole must be made to allow them to diffuse through. This is done using one Or more proteins to create pore in the membrane that allows only specific molecules or ions t0 pass through: 10. Which are the only types of molecules that pass easily through a cell membrane without a protein channel? Positive ions Negative ions Small non-polar molecules Small polar molecules Medium sized polar = molecules What is true" of most naturally occurring pores? They allow only ions to pass through They allow most molecules to pass through They let anything that is the right size through D. They are specific t0 one kind of molecule 699 words 0 English (United States) Focus

Arecent paper in the journal Nature Communications (Kellenberger et al. 2019,Nat: Comm 10.62) demonstrated overdominance in the Alplne orchid Gymnadenia rhellicani: Specifically; genotypes at the anthocyanidin synthase (ANS) locus determine flower color, where heterozygotes (ANS+/ANS-) are red, ANS+/ANSt individuals are black, and ANS-/ANS- individuals are white. Because pollinators prefer the red morph over black or white; red individuals produce more seeds (=offspring) than either homozygote:
