When a new technology is introduced, there is geo-testing performed to see how this new extraction method effects the environment. The over all effects and efficiency are what should determine the acceptance of these solutions.
Answer:
Yes
Explanation:
No matter what age, trees still give out oxygen. It may not be the same amount as an older tree, but it still has the same effect.
The correct answer is: 5) NER recognizes helix distortions, while BER recognizes specific base damage.
DNA damage that occurs as a result of radiation, oxidizing reagents, chemicals and other mutagens can be repaired. Excision repair repairs single strand DNA damage and it includes:
• Nucleotide excision repair (NER)-it detects and repairs types of damage that distort the DNA double helix such as those of UV radiation (thymine dimers); not only the damaged nucleotide(s) are removed but also a surrounding patch of DNA
• Base excision repair (BER)-it detects and removes certain types of damaged bases (small, non-helix-distorting bases); enzyme glycosylase is responsible for this type of repair
Answer:
C. 65 million years ago
Explanation:
The current locations of the continents and their modern day inhabitants, including humans, can be traced to this period.
