The relationship between steroid hormone, estrogen and the peptide hormone, insulin, is being investigated. in order to quantify the levels of each of these hormones, tissue samples were homogenized then placed in a mixture of 2: 1 hexane/water. what's the expected results from this extraction method?
a. estrogen would be in the hexane phase; insulin would be in the aqueous phase
b. both estrogen and insulin would be in the aqueous phase
c. insulin would be in the hexane phase; estrogen would be in the aqueous phase
d. both estrogen and insulin would be in the hexane phase

Every compound can be represented by a chemical formula. a chemical formula is the set of symbols showing the elements that make up a compound and their proportions. water’s chemical formula is h 2 2 o. that means a molecule of water contains two atoms of hydrogen and one atom of oxygen chemically bonded. a molecule is a group of two or more atoms bonded together. molecules can range in size from two to thousands of atoms. a molecule of a compound is the smallest unit of that compound. every molecule of water has all the physical and chemical properties of water. that’s because every molecule of water is made of the same elements in the same proportions: two hydrogen atoms and one oxygen! which of the following is a true statement? a every molecule of the same compound will have different properties. b every molecule of a compound has the same proportion of elements. c molecules can be physically separated into smaller units of a compound. d molecules cannot be represented by chemical formulae.

Has anyone taken the genetics unit test in connexus? not looking for answers, just a little bit what to expect and some with studying.
