Blood Tests
A creatinine level of greater than 1.2 for women and greater than 1.4 for men may be an early sign that the kidneys are not working properly. As kidney disease progresses, the level of creatinine in the blood rises.
        
             
        
        
        
Answer:
The scientific method
:
Make an observation.
Ask a question.
Form a hypothesis, or testable explanation.
Make a prediction based on the hypothesis.
Test the prediction.
Iterate: use the results to make new hypotheses or prediction
Explanation
that's the scientific method but there are many example to how you use it in everyday life i.e the lights went out and you want to find out why, perhaps you didn't pay your bill or maybe the power went out.  then you would go through the steps to find out what happened
 
        
             
        
        
        
Answer:
Frequency of allele A1- 0.41 
Explanation:
In Hardy weinberg equilibrium, 
P refers to the dominant allele 
q refers to the recessive allele
The allele frequency will be p+q=1
The genotypic frequency is- P²+q²+2pq=1
P²= genotype of dominant trait ( A1A1)- 77
2pq= genotype of heterozygotes (2pq)- 65
q²= genotype of recessive trait (A2A2)-  123
Total number of offsprings= 77+  65+ 123
                                             = 265
Now to calculate allele frequency of A1= 

= 77/265 + 1/2( 65//265)
=  0.290+ 0.122
= 0.413
Thus, 0.41 is correct.
 
        
             
        
        
        
Answer:
below
Explanation:
Greenhouse gas increases will cause an increase in desert areas on Earth. Current desert areas will grow as
temperatures cause increased evaporation. Humans will migrate away from these areas of low water and
productivity
