He ability of a stream to erode and transport materials is largely based on its velocity.
        
             
        
        
        
n a cross between two heterozygous individuals, the offspring would be expected to show a 3 : 1 ratio. For example, in Case 1, three-fourths of the individuals would have red (wild-type) eyes, and one-fourth would have sepia eyes.
If there are 44 offspring, how many are expected to have red eyes?
We expect three-fourths to have red eyes.
<span>34</span> of 44 = 33
If there are 44 offspring, how many are expected to have sepia eyes?
<span>14</span> of 44 = 11
Now you are ready to calculate chi-square.
 
        
             
        
        
        
Answer: The receptor site is the location that a drug binds to, altering the function of a biomolecule.
Explanation:
The drug receptors site, are the sites where the sites where the drug molecules bind.  Basically, a low number of receptors exists and the extent to which the molecules occupy their sites differ with the concentration of drug.  The receptor site changes the conformation and function of the binding molecule of the drug.
 
        
                    
             
        
        
        
A change in temperature affects an enzyme by causing the enzyme to change it's shape.
<h3>what is an enzyme?</h3>
An enzyme is a substance that catalyzes chemical reactions. 
- Temperature is one of the major factors that aid enzymes action.
- Increase in temperature could increase the rate of enzyme.
- However, at a very high temperatures, the enzyme can be denatured thereby changing it shape or structure and the enzyme may no longer bind to the substrate or function effectively this will then reduce the rate of chemical reaction. 
 Therefore, a change in temperature i.e very high temperature can change the shape of an enzyme.
