Out of the following
given choices;
a.            Valine instead of glutamic acid in the
sixth position
b.            Glutamic
acid replacing valine in the first position
c.             Extensive
amino acid substitutions
d.            Trinucleotide
repeats
e.            Frameshift substitutions
The answer is A. this is caused by a mutation in the beta
thalassemia genes on one of the 46 human chromosomes (chromosome #11) of the individual.
The alpha subunit is normal in people with sickle cell disease. When sickle
hemoglobin releases oxygen in the peripheral tissues, the molecules tend to
stick together and form long chains or polymers. These rigid polymers distort
the cell and cause it to bend out of shape from
the normative disc shape. 
 
        
             
        
        
        
The specific electrophoretic diagram required to determine the DNA sequence is not found here but this technique refers to Sanger sequencing.
<h3>What is Sanger sequencing?</h3>
Sanger sequencing is a technique used in molecular biology and genetics to determine the linear order of nucleotide bases in a given genomic sequence, which is fundamental to identifying alleles in a genome.
This technique (Sanger sequencing) is based on the use of certain analogous nucleotides that stop the process of amplification, which can be subsequently evidenced in an electrophoresis gel.
In conclusion, the specific electrophoretic diagram required to determine the DNA sequence is not found here but this technique refers to Sanger sequencing.

The medicare part B involves coverage for immunization, Seasonal flu, seasonal H1N1 flu, pneumococcal vaccine and Hepatitis B.
<u>Explanation:</u>
Medicare is a popular insurance coverage for elderly Americans that operates in 4 different modules the part A covers for inpatient expenses , part B covers outpatient expenses, the part C covers alternate medications and the part D covers medicine purchase for part C. All the coverage consists only commercially available vaccines. So the above given vaccines covers in the section of part B of Medicare.
 
        
             
        
        
        
Answer:
Option (A).
Explanation:
Cell membrane or plasma membrane is made up of lipids and proteins with the small amount of carbohydrates are attached to it. This membrane maintains fluidity and separate cell's environment.
Small non polar and uncharged molecules can easily pass through the cell membrane by the process of diffusion. Carbon dioxide and water are small molecules that can easily pass through the membrane.
Thus, the correct answer is option (A).
