Because water and oil don't mix, water is not very effective at washing away oily dirt. The ability of soap to mix with both water and oily dirt allows dirt to be washed away. Which statement provides the most logical chemical explanation for this phenomenon?
A. soap molecules have both positively and negatively charged regions. The positively charged regions are attracted to water; the negatively charged regions are attracted to oil. B. soap molecules have both positively and negatively charged regions. The negatively charged regions are attracted to water; the positively charged regions are attracted to oil. C. soap molecules carry no charge. As a result, soap can form an effective bridge between charged water molecules and neutral oil molecules. D. soap molecules have charged regions and neutral regions; the charged regions are attracted to water molecules; the neutral regions are attracted to oilsE. soap molecules have charged regions and neutral regions. The neutral regions are attracted to water molecules; the charged regions are attracted to oils.

Prokaryotic and eukaryotic cells are different in many ways other than the presence or absence of a nucleus. if both archaebacteria and eubacteria are prokaryotic cells, then why are archaebacteria more closely related to eukaryotic cells than they are to eubacteria?

How many alleles does a gamete carry for each trait? a. one b. two c. millions

4) this is any functional structure within the confines of a cell; literally a. "small organ; " it usually has a membrane-based structure 5) this is a tiny fluid-filled cavity in the cytoplasm. it can be used for storage of biochemicals. 6) this is a two-part process that ends in the assembly of proteins at the ribosomes within cells. the first part, transcription, begins in the nucleus, when the dna code is transferred to mrna. the second part, translation, takes place at the ribosomes, where both mrna and trna work to assemble proteins. 7) these are singular, relatively long, whip-like organelles that many unicellular organisms use for motion. 9) this holds an organisms hereditary information. 10) energy stored in chemical bonds of molecules. - down 1) this kind of cell from a multicellular organism does not have a large central vacuole. 2) this organelle serves to process and package lipids and proteins in the cell. 3) this kind of cell has a large central vacuole and a cell wall. 8) chloroplast thylakoids are frequently stacked to form these disks. submit
