D) Sodium E) Carbon. ______Organic molecules display a great deal of complexity and variations this is due to A) The complex interaction carbon creates with water B) The large number of rare elements that form functional groups in organic molecules. C) The fact that only living organisms can form these atypical bonds in carbon. D) The versatility in the types chemical bonds and chemical partners that carbon atoms can make. E) Their tremendously large sizes. _____ Organisms of same species often have limited difference while member of different species have many differences, these differences. these differences are do to? A) The use of completely different elements for composing molecules from organism to organism. B) Differences in the types and relative amounts of organic molecules synthesized by each organism. C) The use of different types of bonds within carbon molecules between each organism. D) The relative sizes of organic molecules between organisms, the more complex the organism the large the organic molecules become. E) The use of different inorganic compounds with in each organism. ____ In order for carbon to have completely filled it orbital shells stabilizing the shells how many pairs of electron bonds carbon does carbon form in order to complete its valence shell? A) 1 B) 2 C) 3 D) 4 E) 8 ____ You are study a seeding eating bird and are following the carbon atoms in the birds organic molecules which of these statements best describes the carbon atoms present in the bird? A) Ultimately these carbon atoms came from carbon dioxide incorporated into sugars through photosynthesis B) The inorganic carbon from the soil the bird was eating with the seeds C) The carbon atoms in CO_2 the birds was breathing. D) Inorganic carbon atoms in the seeds were incorporated into organic molecules by the bird. E) The carbon atoms ultimately came from simple organic compounds that formed abiotically from inorganic carbon, hydrogen, oxygen, and nitrogen atoms.Explanation / Answer
1. Which of the following element is seen in all organic molecules-
Answer-E) Carbon-
Description-All organic compounds contain carbon. Carbon is so important to the structure of organic molecules that organic chemistry has been called the study of carbon and its compounds. Other elements are readily incorporated into organic molecules.
2. Organic molecules display great deal of complexity and variations due to-
Answer-D) The versatility in the types chemical bond and chemical partners that carbon atom can make
3. Organism of same species often have limited difference while number of different species have many difference this difference are due to-
Answer-B) Difference in the types and relative amount of organic molecules synthesized by each organism
4.Answer-(D)-4
description-a valence electron is an electron that is associated with an atom, and that can participate in the formation of a chemical bond; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair. C atomic number is 6. Makes four electrons available to form covalent chemical bonds.
5.Answer- A) ultimately this carbon atom came from carbon dioxide incorporated into sugar through photosynthesis
description-they were incorporated into organic molecules by plants, they were processed into sugars through photosynthesis and they are ultimately derived from carbon dioxide
