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.
Taste bitter is not the defining characteristic of an acid.
<h3>What is the definition of acids?</h3>
Acids are a type of substance that is very present in our daily lives. For Chemistry, they are substances that release H+ ions in an aqueous solution, decreasing its pH.
In this case, is a characteristic of an acid the turn litmus red, reacts with bases to form salts and react with metals to form H2 gas.

D because the sun is an average sized star
ok so.."Student answers may vary because the pattern in the dinosaur data is not completely similar to that of either ectotherms or endotherms. The graph shows that the metabolic rates of dinosaurs are not quite as high as those of endotherms of similar mass. However, they are also a bit higher than those of ectotherms of similar mass."
you need to look at the graph you have/or the one you made :o
