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.
Answer:
ALS causes the motor neurons to gradually deteriorate, and then die. Motor neurons extend from the brain to the spinal cord to muscles throughout the body.
Answer:
Oxygen and carbon dioxide flow through the blood in the placenta. Most of it goes to the heart and flows through the baby's body. At birth, the baby's lungs are filled with fluid. ... Increased oxygen in the lungs causes a decrease in blood flow resistance to the lungs.
When blood glucose levels decrease, Your liver which is a glycogen storage converts glycogen to glucose and releases it into circulation. Further energy ( ATP Molecules ) is obtained by the TCA Cycle with subtraces like Fat and Protein.
Answer:
Vaccines stimulate the body's own immune system to protect the person against subsequent infection or disease." ... The immune system develops antibodies to the disease so that it cannot make you sick again. Immunization describes the actual changes your body goes through after receiving a vaccine.
