Many scientists support the phenomenon of "obeseogens", industrial pollutants and chemicals found in plastics, food packaging, pesticides, and cosmetics, that contribute to obesity by promoting adipogenesis (increase in number of fat cells) in various organs. this would increase the overall incidence of cancer, because dysfunctional adipose tissue:
a. down-regulates anti-inflammatory molecules such as adiponectin
b. mimics a low grade chronic inflammatory state with pro-proliferative and anti-apoptotic signaling
c. up-regulates molecules associated with invasion and metastasis such as pai-1.
d. mimics a hypoxic state, with upregulation of growth factor and growth factor receptor expression that promote angiogenesis and extracellular matrix remodelling
e. all of the above

Elements and compounds are pure substances that cannot be broken down physically into a simpler substance. a physical change doesn’t break the bonds between atoms of a substance or form new ones. compounds can be broken down by a chemical change. a chemical change breaks chemical bonds and/or forms new ones between atoms of a substance. what simple substance would a compound break into? the basic elements that make it up! for example, if you passed a very strong electric current through water you’d break the chemical bonds in water and be left with oxygen and hydrogen. which of the following is an example of a chemical change? a separating water into different glasses b breaking frozen ice cubes with a hammer c running an electric current through water d boiling water to evaporate it on a stove
