NEED HELP ADAP The graph represents the reaction 2H20 + O2 = 2H202 as it reaches equilibrium. Based on the graph, which two statements about this reaction
are true?
Concentration (mol/L)
- H,09
Time (s)
A. After point 3, the reaction stops.
B. Equilibrium is first reached at point 2.
C. At point 1, the
proceeds mostly in the forward direction.
D. At point 3, the reactants and products reach their equilibrium
concentrations.

When does dna replication(make a copy of itself)?

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.

In german cockroaches, curved wing (cv) is recessive to normal wing (cv+). bill, who is raising cockroaches in his dorm room, finds that the frequency of the gene for curved wings in his cockroach population is 0.6. in his friend joe’s apartment, the frequency of the gene for curved wings is 0.2. one day joe visits bill in his dorm room, and several cockroaches jump out of joe’s hair and join the population in bill’s room. bill estimates that, now, 10% of the cockroaches in his dorm room are individual roaches that jumped out of joe’s hair. what is the new frequency of curved wings among cockroaches in bill’s room? 0.69 0.4 0.5 0.31 0.20
