The question is incomplete as it does not have the options which are:
artificial
enhanced natural
extraterrestrial
manmade
Answer:
Enhanced natural resources
Explanation:
Natural resources are the resources used by the humans for survival present in the environment or provided by the surrounding environment.The natural resources includes the wood, gas, air, water and other substances.
The substances which emits harmful radiations like radium, thorium, uranium are known as radioactive isotopes.
When these ionizing radiation emitting natural substances increases in the environment due to human activities like the particle accelerators, X-rays and other methods which produces these substances then these substances are refereed to as the enhanced natural substances.
Thus, Enhanced natural resources is the correct answer.
Answer: El smog fotoquímico se forma cuando los fotones de la luz solar chocan con moléculas de diferentes tipos de agentes contaminantes en la atmósfera. Los fotones hacen que se produzcan reacciones químicas. Las moléculas de contaminación se convierten en otros productos químicos nocivos, como ya venimos en el laboratorio.
Explanation:
Greetings!
The answer would be A. True.
Dissolved Oxygen is vital for most under water species. There has to be some flow of Oxygen throughout the water for the fish.
That is why most fish that are kept in tanks need filters. The purpose of the filter is to get that oxygen flow throughout the water, and of course keep it clean. Some fish, however will come to the top of the tank to breathe (Beta's for instance). But most fish will need that Oxygen throughout the water.
Hope this helps!
Answer: Sensitivity, reproduction, growth and development, regulation and energy processing
Explanation:
The correct answer is: In DNA and RNA, a phosphodiester linkage connects the 3' carbon of one nucleotide and the 5' carbon of another.
The phosphate of one nucleotide is covalently bound to the sugar of the next nucleotide in DNA molecule (or hydroxyl groups in phosphoric acid react with hydroxyl groups on 3' carbon atom of one sugar molecule (deoxyribose) and the 5' carbon atom of another sugar molecule (deoxyribose) to form two ester bonds). In RNA molecule linkage is between the 3' carbon atom of one sugar molecule (ribose) and the 5' carbon atom of another, (ribose).
Hydrolysis of phosphodiester bonds is catalyzed by the action of enzymes phosphodiesterases.
