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.

Which of the following BEST describes the relationship between concentration and enzyme activity?
nalin [4]

The statement that BEST describes the relationship between concentration and enzyme activity is when substrate concentration decreases, enzyme activity decreases (Option B).

  • Enzymes are proteins that speed up chemical reactions by lowering the activation energy of that reaction.

  • Some factors that alter enzymatic activity include temperature, pH, and substrate concentration.

  • An enzyme works in optimum condition as long as there is more substrate available which can be broken down by the specific enzyme.

  • However, the enzymatic activity increases as the substrate concentration until a limiting value is reached.

In conclusion, the statement that BEST describes the relationship between concentration and enzyme activity is when substrate concentration decreases, enzyme activity decreases (Option B is correct).
