Answer:
1. RNA polymerase binds to the promoter.
2. DNA strands are unwound and separated
3. The complementary RNA nucleotides are added.
Take a look at the attached picture. First, the RNA polymerase must bind to the promoter region to initiate the whole process. DNA must be unwound by DNA helicase, then it will make the RNA transcript, which consists of adding the complementary RNA nucleotides to the DNA strand. Then the transcript leaves the nucleus and begins translation.
 
        
             
        
        
        
Answer:
Letter a) Protists would have less permeable membranes than those in hypotonic or Isotonic environments, wlowing less water to enter the coll. Also, they could possibly develop higher salt concentration within the cell to retain water.

The microorganisms found in soil are important because they affect the structure and fertility of soil. Certain bacteria responsible for nitrogen fixation converts nitrogen in the atmosphere, so that it can be used by plants. Because of microbes, nutrients and minerals are made available to plants. Soil with more diverse microbe will result in fewer plant diseases and better crop yield.
