Answer: This shows that over time, some insects can become "pesticide-resistant" meaning that pesticides don't affect them anymore. And this only happens every few generations. Therefore, each generation is being naturally selected and accumulating variations that make them resist the chemicals. This shows that each cockroach's genes are changing to give them variation from the rest of the population.

Answer:
they help to remove carbon dioxide through calcification
Explanation:
The correct answer would be that <u>they help to remove carbon dioxide through calcification</u>
<em>Shell-building marine creatures play important roles in regulating climate because they help to remove carbon dioxide from the environment through the process of calcification.</em>
Carbon dioxide is a major driver of climate change because the gas is among the greenhouse gases that absorb radiation from the sun thereby causing the warming of the planet. The more the carbon dioxide in the atmosphere, the more the amount of heat trapped and the more the increase in the global temperature. An increase in the global temperature causes the general climatic factors to become erratic.
Hence, the removal of carbon dioxide through the process of calcification is important for regulating climate change.

Answer:
e. None of the above
Explanation:
For me as a Researcher, the reason could be increased Concentration of your DNA sample which you are using as your template. Try to decrease the concentration of DNA (up to 100 ng per reaction is enough and can increase up to 200 ng). so the reason for getting non specific bands is increase concentration of DNA which results in non specific amplification and also degradation of DNA in the reaction which you can see in your gel electrophoresis results.
i always corrected my results using the same technique that is lowering the concentration of DNA between 100 and 200 ng per single reaction of PCR.
