In 1944 Elion joined the Burroughs Wellcome Laboratories (now part of GlaxoSmithKline (a company that makes prescription medicines)). There she was first the assistant and then the colleague of Hitchings, with whom she worked for the next four decades. Elion and Hitchings developed an array (variety) of new drugs that were effective against leukemia, autoimmune disorders, urinary-tract infections, gout, malaria, and viral herpes. Their success was due primarily to their innovative (characterized by new or unique) research methods. Rather than using the trial-and-error approach used by previous pharmacologists, Elion and Hitchings examined the difference between the biochemistry of normal human cells and that of cancer cells, bacteria, viruses, and other pathogens (disease-causing agents). They used this information to create drugs that could target a particular pathogen without harming the human host's normal cells. Their methods enabled them to eliminate much of the guesswork and wasted effort typical in previous drug research.
Answer: 32
Step-by-step explanation:
1. cos of 58 deg= 0.529919264
2. sin^-1 (0.529919264)= 31.999... = 32
Answer:
9.75ft
Step-by-step explanation:
Step one:
Given data
Dimension of the cylinder
Diameter= 6.5 ft
Height= 12.5 ft
You measure the level of milk to be 2.75 ft from the brim
Required
The dept of the milk in the cylinder
Step two:
to get the depth, we need to subtract the measured level from the brim from the height of the cylinder
= 12.5-2.75
=9.75 ft
Hence the Depth of the milk is 9.75ft
