10 Organisms can be classified based on homology, which is shared characteristics inherited from a common ancestor. In the past, homologies were based on studies
of anatomical structures and patterns of embryonic development. In more recent
years, the use of molecular biology techniques has allowed homologies to be
compared at the level of nucleotide sequences. Nucleotide sequence comparisons
are possible because all organisms share which of the following?
F DNA bases
G Cellular organelles
H Division of the nuclear chromosomes
J Types of proteins needed for cellular functions

not only is it colder, it also becomes darker, less salty, and more dense.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
