The model shows two types of proteins, channels and carriers, allowing the movement of molecules into the cell. as indicated by the model, what question is best asked about the role of the proteins in this type of transport? a) how can proteins be used in active transport? b) how do proteins allow for endocytosis of large molecules? c) how can molecules move against the gradient through proteins? d) how do proteins allow for facilitated diffusion of molecules into the cell?

Heyme with this one ❤ ☺❤ name the part of the cell concerned with the transmission of hereditary characters from parents to offspring. "i will mark brainlist "

The earth consists of a variety of different organisms. despite their diversity, however, some similarities on the structural and metabolic levels may be seen. these similarities can be attributed to a. similarities among organisms in their proteins and nucleic acids. b. the ability of organisms to readily adapt to sudden environmental changes. c. similarities in organisms' habitats and niches. d. the ability of all organisms to interbreed and produce new species.

Molecular models of two different substances are shown below. in the molecule on the left, the oxygen atom pulls on electrons more strongly than the hydrogen atoms. in the molecule on the right, the two oxygen atoms pull on the shared electrons with the same strength. water molecule, h,o oxygen molecule, oz when the two substances are put in the same container, they do not attract each other. why does this happen? a. they both contain oxygen. b. one is polar and one is nonpolar. c . they are both polar. d. they contain different elements.
