Answer:
This protein consists of 8 subunits of equal size linked by disulfide bonds
Explanation:
The sodium dodecyl sulfate-polyacrylamide gel (SDS-PAGE) is a technique widely used in molecular biology laboratories to separate proteins with molecular weights between 5 and 250 kDa. SDS is an anionic detergent used to denature proteins before electrophoresis. SDS can denature proteins by altering non-covalent bonds such as hydrogen, hydrophobic and ionic interactions, but they cannot cleave disulfide bonds. In this case, reducing agents (e.g.,  β-mercaptoethanol or dithiothreitol) have been used to cleave disulfide bonds.
 
        
             
        
        
        
The primary products of the light independent reactions  (after one turn of the cycle) are:
a)  two G3P molecules
b)  three ADP 
c) two NADP+
However ADP and NADP+ are not really "products". They are regenerated and later used again in the Light-dependent reactions.  Each G3P molecule is composed of three carbons. 
For the Calvin cycle (Light independent cycle) to continue, 5 out of  the 6 carbons provided by the two G3P molecules are used to regenerate ribulose 1, 5 phosphate. Therefore there  remains only one carbon for the next turn of the cycle.
One  molecule of glucose requires 6 turns of the cycle. Any extra G3P is used to make starch, sucrose and cellulose. 
 
        
             
        
        
        
Do you have choices to choose from? my best guess would be an estuary.
        
             
        
        
        
Answer: CONDITIONS FOR HARDY
No mutations should appear in the beetle population because new alleles would change the allele frequencies 
There should be random mating among beetles 
There should be no natural selection on the beetle population 
The population of beetles must be large enough so that genetic drift is avoided 
There should be no migration of beetles into or out of the population.
CONDITIONS FOR EVOLUTION- 
Natural selection favors green beetles 
Purple mutants appear among the Beatles
Preferred mates are red, so these individuals reproduce
Large numbers of brown beetles were killed in a forest fire 
A significant number of yellow beetles left. 
Explanation: I only added about half the sentence of each answer because it’s to long. 
 
        
             
        
        
        
I believe filtration is the first step in treating lake water. 
Hope this helps!!
