Answer:
A. A genetically engineered crop that is resistant to insect pests could also harm helpful insects.
B. Crops can be genetically engineered to have useful traits that are not found in wild populations,
Explanation:
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.
Answer:
The cell could not make ATP.
Explanation:
Glycolysis may be defined as the process in which a glucose molecule is broken down into the two molecules of the pyruvate. Pyruvate is used to produce energy through various pathways that depends upon the availability of the oxygen. However when the glycolysis in blocked and the pyruvate is not formed, then the cells would not be able to use either the fermentation or aerobic respiration or the perform citric acid cycle. So the cell does not make any ATP.
