Her work not only brought her fame but her death as well; she developed aplastic anemia due to radiation exposure. She experienced recurrent and prolonged infections (viral, bacterial, parasitic, and fungal). Explain why she suffered from recurrent infections. Be sure to mention the different types of WBC and the relation to the various infections, and the reasons why she lacked the cell-mediated and the humeral response.Because of similarities between hypoxia associated with high altitude and COVID-19, some studies have suggested that people living at high altitude may be accustom to low blood oxygen levels and therefore less adversely effected by coronavirus infection. Based on your knowledge of acclimation/adaptations to high-altitude, DISCUSS whether you think high altitude hypoxia might protected against coronavirus infection. Justify your answer. Your words may not be more than 100 words.
- Researchers have suggested that sleep apnoea (the tendency to occasionally stop breathing when asleep) may worsen the effects of allergen-induced asthma. To investigate this possibility, Johnson and colleagues (2015), compared two groups of rats, a normal healthy non-allergic group, and a second group that were mildly allergic to ovalbumin. They subjected these rats to one of two treatments – 1) a 10-minute period of induced hypoxia (oxygen down to 10% of the air), representing the kind of temporary hypoxia that sufferers of sleep apnoea may be subjected to, and 2) a control (normal air) group. They then compared the respiratory function of both groups in these two treatments by using a two-factor ANOVA. (Questions are on the next page).

You have isolated the B cells producing antibodies against the viral H7 protein and fused those specific B cells with a unique kind of mutant myeloma cells. The myeloma cells can't make any of the three following enzymes; dihydrofolate reductase (DHFR), thymidine kinase (TK), and hypoxanthine-guanosine phosphoribosyl transferase (HGPRT). The mutant unfused myeloma cells are grown in the laboratory in a nucleotide supplemented medium. For selecting the hybridomas, you have used a modified medium HT that does not contain any aminopterin but contains hypoxanthine and thymidine. Which of the following result do you expect to see from your experiment, and what problem you may encounter in the future after the hybridoma selection?People infected with SARS-Cov-2(the cornavirus that causes covid-19) can show an array of different symptoms and comlications.
