Students have asked these similar questions
Some scientists propose that Silicon might be a suitable alternative to Carbon as the basicatom that forms the “backbone of life”. Why is this?
Some scientists have speculated that life forms elsewhere in the universe could be based on
silicon, rather than carbon. What properties does silicon share with carbon that makes this more
likely than say aluminum-based life or neon-based life?
explain how the Avery/Hershey Chase experiments proved that DNA is the genetic material.
Is a “trans-fat” a saturated fat, an unsaturated fat or neither? Explain.
Describe three properties of water, and how these properties play a role in the lives of living organisms.

- Consider the following statement. “To produceone molecule of each possible kind of polypeptide chain,300 amino acids in length, would require more atoms thanexist in the universe.” Given the size of the universe, do yousuppose this statement could possibly be correct? Sincecounting atoms is a tricky business, consider the problemfrom the standpoint of mass. The mass of the observableuniverse is estimated to be about 1080 grams, give or takean order of magnitude or so. Assuming that the averagemass of an amino acid is 110 daltons, what would be themass of one molecule of each possible kind of polypeptidechain 300 amino acids in length? Is this greater than themass of the universe?arrow_forwardA famous experiment used the chemicals found in the early atmosphere of the earth and added energy from electrical sparks to show that the beaker accumulated the building blocks of life (the monomers, such as amino acids). Is it also important to show that the early earth was able to polymerize these building blocks of life into chains of monomers (polymerization with chemical bonds between monomers)? Why?arrow_forwardThe percentages of naturally occurring elements making up the human body (see Table 2.1) are similar to the percentages of these elements found in other organisms. How could you account for this similarity among organisms?arrow_forward

- Several emergent properties of water contribute to the suitability of the environment for life. Choose two properties of water and describe how these properties arise from the structure of water molecules. Next choose any organism, and give specific examples of how the properties of water you described contribute to the survival of the given organism.arrow_forwardThe following is made up of two or more different types of elements grouped together as a unit: O a. Cell Ob. Atom O c. Molecule O d. Compound Oe. Tissuearrow_forwardOften, complex molecules are described in terms of their atomic masses. But what is more relevant in biology is how they take up space. (For proteins, their shapes are particularly important.) Let's see if we can get an approximate idea of the physical size of a protein molecule by doing various estimations. An important molecule in the internal mechanisms of cells is Actin. This is measured as having a mass of about 42 kDa (= 42,000 Daltons, where 12 Daltons is defined as the mass of a carbon atom). Let's see if we can estimate how big it is using very crude estimates. Of course eventually we will want to know how big it actually is and what its shape is, but getting a scale would help us determine what measurement tools might be appropriate. In order to estimate the size of Actin, we'll first make an estimate of how many atoms it has, then, using the average size of an atom, we'll consider different models of how it might be arranged to get an idea of its size.
