Answer:
Maltose is a disaccharide sugar made up of two units of glucose.
In cyclic structure, the glucose exists in two anomeric forms; alpha and beta.
These glucose units can either joined by α (1→4) glycosidic bond or by β (1→4) glycosidic bond.
Thus, the maltose exists in two anomeric form alpha and beta.
 
        
                    
             
        
        
        
This was Ernest Rutherford’s gold foil experiment. He used radioactive alpha particles as a part of the experiment and discovered that there was a densely packed, positively charged nucleus in atoms with electrons that were spread out in spaces between nuclei.
        
                    
             
        
        
        
If it was a double heterozygote, then aabb will be AaAaBbBb.
It will form 4 types of gametes since we have Aa, Bb.  It will have aB, AB, ab, Ab.
An individual will form 
only 2 type of gametes, Aa, Bb.
 
        
             
        
        
        
Answer: Hemoglobin
Explanation: Hemoglobin is a protein very rich in iron found in red blood cells and is responsible for the transportation of Oxygen from the lungs to the whole body. Oxygen binds to the hemoglobin in red blood cells and the red pigmentation of blood that is highly oxygenated is due to the hemoglobin content found in RBC's. 
 
        
             
        
        
        
I would guess rainforest because it’s an reptile/amphibian it appears and those animals need water to survive. There isn’t much water in the dessert.
