A species could be a mimic if it's colors are slightly off from the creature they're trying to mimick, or, upon closer inspection, have a different body shape than the creature they're trying to mimick.
 
        
             
        
        
        
Answer:
The reduced form of cytochrome c more likely to give up its electron to oxidized cytochrome a having a higher reduction potential.  
Explanation:
Electrons from NADH and FADH2 flow spontaneously from one electron carrier of the electron transport chain to the other. This occurs since the proteins of the ETC are present in the order of increasing reduction potential. The reduced cytochrome b has lower reduction potential than cytochrome c1 which in turn has a lower reduction potential than the cytochrome c. 
Cytochrome c is a soluble protein and its single heme accepts an electron from cytochrome b of the Complex III. Now, cytochrome c moves to complex IV which has higher reduction potential and donates the electron to cytochrome a which in turn passes the electrons to O2 via cytochrome a3.
 
        
             
        
        
        
Answer:
Option B: Molecule 2
Explanation:
'Equilibrium of a molecule inside and outside a cell' means that there are similar numbers of that molecule on the inside and the outside. (hence 'equilibrium')
The number of each molecule is as follows:
Molecule 1 - Inside: 3, Outside: 5
Molecule 2 - Inside: 2, Outside: 3
Molecule 3 - Inside: 1, Outside: 5
Molecule 4 - Inside: 7, Outside: 4
Therefore the correct option is option b. 2
This is because the number of molecules inside the cell and outside the cell are the closest together, most similar out of all the molecules.
Hope this helped!
 
        
             
        
        
        
Answer: (B)
Explanation: They are asking for a comparison between light waves and sound waves.
A  and C is wrong because it only says about sound waves
D only says about sound waves
E is completely wrong because they are affected differently in different mediums.
 
        
             
        
        
        
Meiosis is needed for sexual reproduction, here chromosome number is halved, it provides for mixing up of genes.
 mitosis is needed for growth, repair, replacement, asexual reproduction.
it maintains same chromosome number
