These large aircraft carriers are usually located in the middle of the ocean, in a location where an airport or landing location on land is not accessible. USS Dwight D. Eisenhower is a nuclear powered aircraft carrier that is currently in service with the United States Navy.
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.
<span>All cells use oxygen to convert raw food products into energy they can use for health. In the process they make a bi-product which is carbon dioxide and waste material. If there was no cellular respiration the cell would die, because they would be lacking the oxygen needed for food conversion, and they would have no means of getting rid of their waste products.</span>
