The answer is <span>B. In both oogenesis and spermatogenesis, the cells become haploid after meiosis I.
Gametogenesis is a process in which gametes are produced. Oogenesis is a process in which egg cells are produced and spermatogenesis is a process in which sperm cells are produced. Both processes include meiosis.
Original diploid cell (primary oocyte or spermatogonium) has 46 chromosomes. After meiosis I, there are two haploid cells. After meiosis II, there are 4 haploid cells because meiosis II is similar to mitosis. The difference between spermatogenesis and oogenesis is that those 4 cells after meiosis II in spermatogenesis are all sperm cells, and in oogenesis only one of them is egg cell.</span>
        
                    
             
        
        
        
That would be D. Isovolumic contraction 
As the name states during ISOvolumic contraction the volume of the ventricles doesn’t change and stays the same so no blood enters or leaves the ventricles. The thing that changes is the pressure of the ventricles that increases. 
I can explain the process more if u want in the comments:)

The teacher
should discuss safety procedure with students at the beginning of the experiment
or laboratory assignment.  The teacher
should give list of rules for students. 
1.      
Always wear safety goggles.
2.      
 Never
touch or rub eyes of face during science investigation.
3.      
Keep lids on when not in use.
4.      
Never use broken/chipped glassware. 
 
        
                    
             
        
        
        
The pattern of criss-crossing strips of pastry on top of food is called a quadriller. It can be done with the back of a knife such as fish, scallops, etc. Examples include: meat on the grill or <span>criss-cross strips of pastry on top of a pie.</span>
<span> The goal of the pattern is to improve food presentation and make it look more interesting.</span>
