Answer:
S. aureus strain is less infectious, but its alpha-toxin is highly-toxic.
Explanation:
Given data:
LD50 for S. aureus alpha toxin 0.45 \mu g/kg
ID50 for same mouse density found to be 200,000
From the data information given above Staphylococcus aureus was done on mice. The result show that LD50 is found to be 0.45\mu g/kg and ID50 found to be 200,000 on same mouse population
the result taken together mean that S. aureus strain is less infectious, but its alpha-toxin is highly-toxic.
Im going to assume you mean the structural formula of butane, which is C4H10. which mean that it has 4 carbon and 10 hydrogen
Answer: energy of infrared radiation=13.75×10^-20J
Energy of ultraviolet radiation=8.5×10^-19J
Energy of xrays=3.7×10^-17J
Explanation:
Energy of radiation= h×c/wavelength
h=6.6×10^-34 Js
c=3×10^8 ms-1
For infrared= 6.6×10-34×3×10^8/1.44×10^-6=13.75×10^-20J
For ultraviolet= 6.6×10^-34 × 3×10^8/233×10^-9=8.5×10^-19J
For xrays= 6.6×10^-34×3×10^-8/5.34×10-9=3.7×10^-17J
