Answer:
B
Explanation:
An alkylating agent adds an alkyl group to the DNA strand of a specific cell group highly prone to being cancerous. This action is exactly what Cisplatin does by disrupting DNA replication (mitosis) for cancerous cells by inserting itself into a DNA strand.
 
        
                    
             
        
        
        
Answer:
The correct answer is option a, that is, sympatric speciation. 
Explanation:
Speciation, which takes place when two groups of similar species live in a similar geographical location, however, they evolve distinctly unless and until they no longer interbreed and are regarded as different species is termed as sympatric speciation.  
Sympatric speciation is not similar to other kinds of speciation, in which the formation of a new species takes place when a population gets differentiated into two groups because of migration or geographic barrier. The sympatric speciation can be witnessed in various distinct kinds of species. Thus, the given case of monkeys is an illustration of sympatric speciation.  
 
        
             
        
        
        
The measure of side b as 64 ft is incorrect. The accurate measure would be 8 ft.
According to the Pythagorean theorem, the square of the hypotenuse of a right-angle triangle is the sum of squares of the opposite and the adjacent sides. Mathematically:

In this case, the hypotenuse = 10 ft, the opposite = 6 ft and the adjacent = b
Hence,
b^2 = 10^2 - 6^2
        = 100 - 36
           = 64
b = √64
      = 8 ft
Thus, the side b is 8 ft and not 64 ft.

Answer:
I think the answer is C. between 6.5 and 7.5 because cells usually have a ph between 7.0 and 7.4

The OH on the lower right of lysine and the H on the lower left of valine combine to form a molecule of water (H2O) and detach in a process known as a dehydration reaction when the two amino acids bond. The C on the right side of lysine then single bonds with the N on the left side of valine. This bond is termed a peptide bond. All the other bonds remain unchanged.
