The answer is:
<span>Step 1 Genetic material duplicates.
</span>Step 2 Cell grows in size and other <span>organelles duplicate.
</span><span>Step 3 Cell wall or membrane forms.
</span>Step 4 Cells separate.
Binary fission is a type of cell division characteristic for prokaryotic cells. In this process, after the cell reaches its maximum size, the genetic material starts to duplicate. These two copies of genetic material are now connected to plasma membrane. The cell begins to grow in size and thus separate those two copies of genetic material. Other organelles are duplicated, too. Next, a new cell wall or cell membrane starts to grow in the middle of the cell leading to the separation of the cell. 
        
                    
             
        
        
        
Option B
Middle colic arteries is the most likely additional  source of blood to the descending colon
<h3><u>
Explanation:</u></h3>
The middle colic artery is a section of the superior mesenteric artery. Middle Colic provides the transverse colon, has a branch that runs to the right colon and branch that persists to the left colon that catches up with the left colic artery and proceeds as the marginal artery to provide the descending colon.
The left gastroepiploic artery is one of the sections of the splenic artery. Sigmoid- branch off IMA so barred in this case Splenic- proceeds of the celiac trunk, branches accumulation spleen & pancreas Superior Rectal- a sequence of IMA not possible to participate in this case
 
        
                    
             
        
        
        
Oceans bring warm water to distant shores. Ocean temperatures and winds are coupled into a complex interactive system. Varying ocean temperatures affect local atmospheric pressure, which creates regional wind patterns that, in turn, drive oceanic currents that affect surface ocean temperatures.
        
             
        
        
        
Answer: If the carbon bonds are on a different charge or one is not charged evenly it will break or maybe misshape the membrane.

Answer:
Frequency of allele A1- 0.41 
Explanation:
In Hardy weinberg equilibrium, 
P refers to the dominant allele 
q refers to the recessive allele
The allele frequency will be p+q=1
The genotypic frequency is- P²+q²+2pq=1
P²= genotype of dominant trait ( A1A1)- 77
2pq= genotype of heterozygotes (2pq)- 65
q²= genotype of recessive trait (A2A2)-  123
Total number of offsprings= 77+  65+ 123
                                             = 265
Now to calculate allele frequency of A1= 

= 77/265 + 1/2( 65//265)
=  0.290+ 0.122
= 0.413
Thus, 0.41 is correct.
