The question lacks the diagram. The diagram has been attached below. 
Answer:
1.
Explanation:
Exons may be defined as the coding region of the RNA whereas introns are the non coding region of the RNA. The introns must be removed out from the RNA to makes it functional molecule.
The splicing of the given molecule results in the formation of single mRNA. The 1 splicing of the introns remove intron A whereas the second splicing results in the removal of intron B. The functional mRNA consists of the mRNA with exon 1,2 and 3.
Thus, the answer is 1.
 
        
             
        
        
        
1. <span>what is the amount of the bolus dose, in both milligrams and milliliters, that you will administer in the first minute? 
</span>The doses is 0.9 mg/kg and the weight of the patient is 143 pounds. So, the total doses of drug needed will be: 
Total doses= 0.9 mg/kg * 143 pounds * 0.453592 kg/pound= 58.37 mg.
10% of the doses will be given bolus for 1 min, so the amount would be: 
Bolus doses= 10%*58.37 mg= 5.837 mg.
In mililiters, it would be: 5.837 mg * 1ml/mg= 5.837 ml.
<span>2. what is the amount of the remaining dose that you will need to administer?
The remaining dose would be 90% of the total dose. You can either calculate it directly or subtract the bolus doses from the total doses.
Remaining doses= total doses- bolus doses= </span>58.37 mg- 5.837 mg= <span>52.533mg</span>
        
             
        
        
        
Answer:
A  genetic disorder that is inherited as a recessive trait is sickle cell anemia.
Explanation:
Sickle cell anemia can be described as a disorder which is caused by a mutation in the hemoglobin beta gene which is found on chromosome number 11. The pattern of inheritance of sickle cell anemia is autosomal recessive which means that both the alleles of the gene shall be recessive for the trait to occur. A person with one recessive allele for the trait will not carry the disease but will be a carrier for the disease. 
 
        
             
        
        
        
During the second gap, or G2 phase, the cell continues to grow in size and produce proteins necessary for cell division. Microtubules, filamentous internal structures, necessary for separating the chromosome copies are made during this phase. The second internal checkpoint that determines if the cell can continue through its cycle occurs in G2. While the G1 checkpoint checks to verify DNA is error free before replication, the checkpoint in G2 confirms the new DNA is error free after replication
