Because the genetic code is a universal code in biology, in general the nucleotide sequence of important genes is highly conserved across many different species of organisms. It is very common for 70% or more of the nucleotides in a gene to be conserved among very different organisms. Redundancy in […]

I need help answering these exam review questions. Describe the basic structure and components of atoms and reactions essential to life. Describe the significance of carbon in forming the basis of the four classes of biologically important organic molecules. Differentiate between hydrolysis and dehydration synthesis reactions as processes of metabolism. Describe in specific terms the forms and functions of the four classes […]

Analysis of an electron transport system in the cell membranes of a previously unknown Kingdom of organisms revealed that it contained the following components with the redox half-reactions and standard reduction potentials shown in the Table. Half-Reaction E’o(V) Cytochrome R+ + e → Cytochrome R +0.35Cytochrome T+ + e → […]

Question: If there is no heritability for shell thickness within a population of snails, what happens to shell thickness in response to crab predation? Question: Create the psychometric function that you would expect if the returned echo is shifted by 90 degree relative to the outgoing pulse of the echolocating bat, Eptesicus. Show […]
