Large animals need specialized organs for gas exchange because . a volume increases more rapidly than surface area as size increases b they require more oxygen per unit of volume c surface area increases more rapidly than volume as size increases d they collect more energy and therefore have more energy to allocate to specialized tissues

Which part of the cell is affected by the movement of molecules through diffusion, osmosis and active transport?

What are the student's observations and inferences before he starts his investigation?

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
