Answer:
C
Explanation:
Semiconservative replication means that strand will also be used. (Pretty sure)
Answer:
Low - The generation of nitrates (NO 3-) requires oxygen, so the oxygen levels will be low
Explanation:
Nitrates are formed when the ammonia react with oxygen present in water. The oxygen which react with ammonia is not the oxygen of water molecule, it is the dissolved oxygen. This oxygen is used by aquatic animals for breathing. If nitrates are formed so the concentration of dissolved oxygen will be lowered which causes suffocation and bad impact on marine organisms and the whole ecosystem will be disturbed.
Answer: The statement is false
Explanation:
Addition of concentrated sulfuric acid (H2SO4) to a beaker full of water (H2O) will release heat energy to the containing vessel due to the breakage of strong ionic bond present in the acid.
Thus, it is an evidence of a EXERGONIC REACTION (since energy is released spontaneously). So, the statement is false
Answer:
In a particular case of secondary succession, three species of wild grass all invaded a field. By the second season, a single species dominated the field and the other two species had a lower relative abundance. A possible factor contributing to the abundances of these species in this example of secondary succession is <u>inhibition</u>.
Explanation:
Trees are great examples of allelopathy in plants. Some use their allelochemicals to inhibit germination or impede development of nearby plant life. Most allelopathic trees release these chemicals through their leaves, which are toxic once absorbed by other plants. Black walnut is a prime example of this.
It allows scientists to explore new explanations for observations.
