The right answer is C
This process is called anaerobic respiration. It doesn't need dioxygen to occur (it can happen with or without O2).
Anaerobic respiration is a mechanism in which electrons pass through a chain of transporters whose final acceptor is a mineral substance other than oxygen, unlike aerobic respiration where the final acceptor is dioxygen. The final acceptor may be the nitrate ion (as in the case of Pseudomonas), carbon dioxyde or the sulfate ion.
Some bacteria (Pseudomonas) are able, anaerobically, to reduce nitrates to nitrites and then, depending on the case, to dinitrogen (with the enzyme Nitrate reductase A).
NO3- ==> NO2- ==> N2.
According to lecture, the level of emission reductions pledged by individual countries at the paris climate agreements are sufficient to prevent dramatic climate change according to many scientists. <u>The statement is False.</u>
The issue is that many scientists believe the existing pledged emission reductions won't stop serious climate change.Leading the way in global efforts to combat climate change has been the EU. It played a key role in negotiating the Paris Agreement and continues to lead the world.
The EU presented its updated and improved NDC in December 2020, along with information to promote the ICTU (clearness, transparency, and understanding) of the NDC and a target to cut emissions by at least 55% from 1990 levels by 2030.
By working together, the EU and its Member States are committed to a legally-binding goal of a net domestic reduction of greenhouse gas emissions of at least 55% from 1990 to 2030.

The big bang theory states that the universe began approximately 10-20 billion years ago in an expansion of the universe emanating from an extremely compact point. The occurrence of super massive black holes contradict the big bang theory. Super massive black holes are found at the center of galaxies and is what keeps them together. Models do not explain how these would have formed if the big bang occurred the way it was proposed.
Knowing that she is already 75 years old, even though we don't know her health conditions, we can conclude that the vitamins might help her to avoid any deficiency related to minerals and vitamins, and it might also help her if she has an alimentary restriction meaning that she can't it a food that contains a needed vitamin or mineral.
Hope it helps,
Happy homework/ exam/ study!
<span>Forebrain. Forebrain is related to functions of cognitive activities. It is part of brain with other two parts which are hind brain and mid brain. Amygdala related to emotions. Midbrain related to vision, hearing etc. while hindbrain is concerned with control involuntry functions like respiration.</span>
