Answer:
Explanation:
Duchenne muscular dystrophy acts as a X-linked recessive disease. Which means the gene sits on the X chromosome, and you need two bad copies to show disease (for females) and one bad copy (to show in males).
Now from our knowledge, we know males are XY and females are XX. Males have only one copy of the X chromosome from their mother and one copy of the Y chromosome from their father, thus if they get the mutated version of the gene that causes this disease, they will get the disease. However, if a female has a mutated version of gene on one of the X chromosome, the other X chromosome could have a normal gene and that normal gene would take over and produce a normal phenotype/function.
Since, boys only have one X chromosome, if they get the mutated gene they will get the disease, whereas females have two X chromosome (so even if one copy is bad and the other is good, the good version can take over, however boys don't have this) thus mostly male children are affected by this.
The chief difference between arteries<span> and </span>veins<span> is the job that they do. </span>Arteries<span> carry oxygenated blood away from the heart to the body, and </span>veins<span> carry oxygen-poor blood back from the body to the heart.
Another difference would be v</span><span>eins have valves and arteries do not. In arteries, blood flows in the right direction because of the heart pumping it forwards at high pressures. The lower blood pressure in veins means that valves are needed to stop blood flowing backwards (for example, in veins in the legs, blood needs to flow upwards against the pull of gravity).</span>
<span>Therapeutic cloning means that it could be used to heal people so the best way to benefit the society while doing this would be to help cure diseases. Example would be cloning body parts and testing diseases on them and then developing medication that can help against them. Also you could clone exact body parts that fit you so you could have a new kidney or lungs if necessary that fit you perfectly.</span>
Answer:
b) Have a variable region that can activate complement or attach to macrophages.
Explanation:
Antibody:
Antibodies are the part of immune system that is protein in nature and produced to protect body from pathogens such as bacteria and viruses. These pathogens are recognized through the fragment antigen-binding variable region. Antibodies are also known as immunoglobulin.
Gamma globulins are the class of globulins, Antibodies are the most significant gamma globulins but it should be remember that some antibodies are not gamma globulins.
Correct Answer:
On the basis of above knowledge discussed the correct answer of this question is option b i.e Have a variable region that can activate complement or attach to macrophages.
A triglyceride is the most common fat found in foods and in the body. It gives more than twice as much energy compared to carbohydrates and protein. Triglyceride is made up another three molecules such as carbon atoms, hydrogen atoms and oxygen atoms. A hydroxyl group being the unit of hydrogen and oxygen atoms is represented as OH. The hydrogen and oxygen atoms are being bonded to each other. The carbon atoms are also bonded with each other wherein the oxygen atom will be attached to the carbon atom.
