Answer: I am a Shrub
Explanation:
A Shrub also called a bush  is medium-sized woody plant  with many stems which is shorter than a tree but taller than a  herb  having a range in height of about 6-10 metres  Shrubs are divided into two --- Deciduous and evergreen.
Many Shrubs are planted in  homes and gardens because of the  aesthetic value they provide,  including serving as wind breaks when many of them are planted together.Example of Shrubs include  Rose, jasmine,Hibiscus  tulsi, etc.
 
        
             
        
        
        
Answer:
Polymerase chain reaction (PCR) test is used to duplicate traces of DNA from any living form, for identification purposes.  The correct sequence is 1, 3, 2; based on the options given.
Explanation:
The steps to be followed for the PCR procedure are:
<em>Denaturation</em>
Option 1.  Involves incubation at 94°C to denature DNA strands into single strands by breaking of weak hydrogen links
<em>Annealing</em>
Option 3.  Temperature is lowered to 60°C to allow primers joining their similar DNA sequences.
<em>Elongation</em>
Option 2.  Incubate at 72°C to promote the extension of the DNA strands, actually extending them.

Answer:
Explanation: When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective. ... this is actually why cells divide.

Air pressure (inside the lungs) is lowest when lung volume is highest, so the answer is B. when you breathe in your lungs expand, which makes the air molecules spread out, therefore the pressure is lower.
