Answer:
Cb>Cy>Co>Cr
Explanation:
First of al we need to do the Punnett square. As a result we get the genotypes:
CyCb
CyCr
CoCb
CoCr
Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype. 
Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.
The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.
As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.
 
        
             
        
        
        
Answer:
A decrease in pH is too acidic compared to optimum pH for amylase activity. The hydrogen ion changes amylase sites of activity and amylase activity become low. At pH 13 to 1 which is acidic, reduces the activity of amylase because the hydrogen ion changes amylase activity sites and render it's action low which will denatures amylase and make it ineffective.
Explanation:
Amylase refer to enzymes that catalyses or breakdown starch into sugars. General, enzymes are biological substances that speed up the rate of chemical reactions.
Enzymes generally are affected by pH. The most favorable pH is the optimum pH which make amylase to be effective or enzymes.
A high pH or low pH has effect on the enzymes and will reduces enzymes activities. A low pH will cause the hydrogen ion to alter the enzymes sites and reduce their activities while high pH will cause the hydroxides ion to alter the enzymes activity sites.
