Answer:
126 mm Hg
Explanation:
the percentage by volume of oxygen in the air is 21%. Therefore it also contributes to the 21% of the total barometric pressure of the air.
Now, 21% of 600 mm Hg
=21/100*600= 126mm Hg
therefore The partial pressure of O2in Antonito’s air is approximately is 126 mm of Hg.
It occurs polyuria. Polyuria is, in other words, to urinate a lot, abnormally. If the patient drinks enough water to compensate the loss of it by urination, then the outcome is not as severe. If the patient does not take enough water, dehydration and h<span>ypernatremia take place and blood pressure increases and several other complications.</span>

Answer: B. by toxic chemicals (in smoke) or radiation that can damage the DNA in cells.
Explanation:
The carcinogens presents in cigerates covalently bind to DNA and form DNA adducts which results into miscoding (e.g., insertion of the wrong base) during replication of DNA and this genetic mutation causes uncontrolled cellular growth which causes cancer.
Ionising radiation including X-rays, radioactive particles, and gamma rays,can cause cancer by damaging DNA. high-energy radiation damages DNA and cause genetic mutation same as cigerates and causes cancer.
Both toxic chemicals (in smoke) or radiation damages DNA inthe cells which leads to cancer.
Hence, the correct option is B.
