PLEASE HELP ASAP What will occur if a species is divided into two groups and allowed to reproduce in different environments for many generations?
1. divergence, potentially giving rise to two different species
2. random mutations, all of which will decrease fitness
3. divergence, but these will never be two different species
4. natural selection, keeping both groups genetically static

Which nucleotide component contains nitrogen

An enzymatic hydrolysis of fructose-1-p, fructose-1-p(aq) + h2o(l) - fructose (aq) + pi (aq) was allowed to proceed to equilibrium at 25°c. the original concentration of fructose-1-p was 0.2 m, but when the system had reached equilibrium, the concentration of fructose-1-p was only 6.52 x 10^-5 m. calculate the equilibrium constant for this reaction and the free energy of hydrolysis of fructose-1-p.

The human body maintains a temperature of around 98.6 degrees at all times. enzymes are involved in almost every chemical reaction in the body. which of the following describes the connection between these two statements? a. enzymes function best at a specific temperature. b. the body needs to be warm to prevent hypothermia. c. the body is kept relatively warm to prevent too much enzyme action. d. there is no connection between the two statements.
