Answer:
The correct answer is:
a)FADH2
c)GTP
e)NADH
Explanation:
The Citric acid cycle(TCA) also known as the <em>Kreb cycle,</em> is a focal metabolic center of the cell. It is a sequence of chemical reactions in which the acetyl portion of acetyl CoA is degraded to carbon dioxide and hydrogen atoms.These reactions all occur in the matrix of the mitochondria. This cycle is also an important source of precursor for other molecules such as amino acids, nucleotide bases cholesterol etc. The function of the citric acid cycle is the gathering of high-vitality electrons from carbon fuels. The citric acid cycle removes electrons from acetyl CoA and use it to reduce NAD and FAD into NADH2 and FADH2 respectively.
<em>Overall, The citric acid cycle oxidizes two carbon units(from acetyl CoA) and produces two molecules of carbon dioxide, one molecule of GTP and high energy electrons which are present in the form of NADH2 and FADH2</em>
 
        
             
        
        
        
Question 1:
Basically, producers are things like plants the are the first source of food. Primary consumers are the first to eat the producers (like small fish, insects, etc) Secondary consumers (foxes, larger fish, etc) consume the primary consumers, and tertiary consumers (sharks, humans, whales, etc.) consume the secondary consumers. Decomposers (fungi, bacteria, etc) like the name suggests decompose rests of food and organisms and send the nutrients back into the earth.
Questions 2&3:
An autotroph is an organism that produces its own food (like plants do through photosynthesis) and a heterotroph is an organism that cannot produce its own food and has to seek out other sources of food.
Question 4:
Grass, Dragonfly, Trout, human
Question 5:
Bean plant, rabbit, fox, bacteria
Questions 6&7:
They are a little harder to explain in text form but hopefully my explanations can help you figure out the answer yourself.
Hope this helped!
        
             
        
        
        
When the electron wavefunction is bound in a stable state in an atom it stretches into a 'orbital' form. There was a mistake. When attached in a stable atomic state, an electron often acts like a three-dimensional oscillating wave, i.e. the orbital vibrates. It's sort of like a vibrating chord.
        
             
        
        
        
Pioneer species can decrease if other species move it out. If the pioneer species in a forest area is a type of bush, that bush might decrease in number as more species come in.
