In one hypothesis about the origin of life on earth, scientists propose that organic molecules were produced from inorganic molecules in chemical reactions. how would you evaluate a scientist's claim that reactions, showing organic molecules emerging from inorganic molecules, can be seen in nature today? ( 2 points) a the claim must be false because modern-day evolution cannot be observed and recorded. b the claim is likely to be false because the current conditions on earth are opposed to the formation of life. c the claim is likely to be true because all the elements necessary for the formation of organic molecules are present on earth. d the claim must be true because scientists are able to replicate these reactions in a lab.

answer; ///(b) it is composed of four protein chains and four heme groups;

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.

a = executive branch; b = judicial branch

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
