<span>Some of the things that would make the experiment invalid would be, if there was a variation in the behavior of the class with respect to food - for example, if some people ate their breakfast earlier than the others. This then would mean that some students would have already digested their breakfast during the morning classes and the others would still be digesting. </span>
The homeostatic control system component which transmits the
response is called the receptor.
To add, the receptor is <span>an organ or cell able to respond to light,
heat, or other external stimulus and transmit a signal to a sensory nerve.</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.
ATP has one more phosphate group than ADP
Explanation:
heat (metal or glass) and allow it to cool slowly, in order to remove internal stresses and toughen it.
OR
recombine (DNA) in the double-stranded form following separation by heat.
