Established on the data, sickle cell hemoglobin displays altered primary structure and altered quaternary structure; the secondary and tertiary structures may or may not be altered. The sickle cell disease is a cluster of disorders that disturbs hemoglobin, the molecule in red blood cells that transports oxygen to cells all over the body. A person with this disorder have uncharacteristic hemoglobin molecules named hemoglobin S which can interfere with red blood cells into a sickle or crescent shape.
Answer:
The pulmonary artery carries deoxygenated blood (blood whose oxygen content is relatively low) from the right ventricle to the lungs. The blood here passes through capillaries to alveoli and becomes oxygenated (as part of the process of respiration).
The image provided is not clear, however, the correct and clear image is attached with the answer:
Answer:
The correct answer is - 100 %
Explanation:
As we know DMD or Duchenne Muscular Dystrophy is a sex-linked recessive disorder and according to the given pedigree, it is clear that Individual I-1 is a normal male and 1-2 is a female who has two defective genes of the disorder as if she had only one defective gene she would have a carrier for the disorder.
All gametes produced by both male and female would be -
Male - X and Y
Female - Xd and Xd
Therefore all the male offsprings or son will get one defective gene Xh from the mother for sure and a Y chromosome from the father. All daughters will also carry one gene Xh that is defective from the mother and normal X from the father but would be carriers for the disorder.
In my opinion, nuclear war will is the biggest threat and we need to prevent that from happening. If a nuclear “world” war does occur, the war would end up killing every or most of the world population, as well as other living things of course. Instead of expanding our own nuclear energy, we should focus on making and upgrading nuclear bunkers to shield us from the war and radiation.
