Answer:
Interphase, mitosis, and cytokenesis
Explanation:
Interphase is the phase in which the cell is growing, and mitosis and cytokenesis make up the phase in which daughter cells are formed 
 
        
             
        
        
        
Answer:
True.
Explanation:
The Hund's Rule states that all orbitals must be singled occupied before any orbital is doubly occupied, and all the electrons at the singly occupied orbitals have the same spin number. By doing that, the electrons filled the lowest energy orbitals first. 
 
The 2p level has 3 orbitals: 2px, 2py, and 2pz. So, when filling it, first put an electron in the 2px, then in the 2py, then and the 2pz (all with the same spin). After that, the remains electrons can be paired up. 
 
        
             
        
        
        
Answer: The final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M
Explanation:
According to the dilution law,
 
where,  
 = molarity of stock
 = molarity of stock  solution = 2.5 M
 solution = 2.5 M
 = volume of stock
 = volume of stock  solution = 5 ml
solution = 5 ml  
 = molarity of diluted
 = molarity of diluted  solution = ?
 solution = ?
 = volume of diluted
 = volume of diluted  solution = 750 ml
 solution = 750 ml
Putting in the values we get:
 
 
Therefore the final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M
 
        
             
        
        
        
Answer:
c. contraction
Explanation:
Heating will cause substances to expand, or change their state (like solid to liquid) or it may be a chemical reaction.
 
        
                    
             
        
        
        
Answer: A closed system, because energy can enter or leave the container, but the water molecules cannot
Explanation:
Open system: In this system energy and matter both have access to their surroundings beyond the boundaries of system. .
Closed system :In this type system only energy has an access to its surroundings beyond the boundaries of system but not matter.
Isolated system:In this type system exchange of both energy and matter are restricted to move outside the boundaries of system.
According to question, the system given is a closed system because energy is transferred from the burner to glass flask and from the glass flask to the water (matter). But water molecules are only getting condensed on the inside surface of the flask that is exchange of matter beyond the boundaries of the system is restricted. Hence, closed system ,A closed system, because energy can enter or leave the container, but the water molecules cannot.
