Yes, Avery, Mc Leod and Mc Carty do thought that genes may be involved in the transformation of non virulent rough Strains of <em>Diplococcus pneumoniae</em> to harmful smooth strained bacteria 
<h3><u>Explanation:</u></h3>
Avery was a Canadian medical researcher who along with other two well known scientists of the contemporary time went for an experiment where he took two strains of bacteria Diplococcus pneumoniae - one is rough and nonvirulent and another is smooth and virulent. For a control run, he injected both the bacteria in separate mice and the expected result was there. Now as he injected heat killed smooth bacteria, the mice survived. But as he injected heat killed smooth bacteria with rough bacteria, although there was no organism which can kill the mice the mice died. And autopsy revealed the presence of live smooth bacteria in the lungs. 
Thus they suspected something have gone from the dead smooth bacteria into the non virulent rough bacteria which lead to transformation of the rough bacteria to smooth ones. Thus, the experiment was carried on, which suspected role of genes in this transformation. 
 
        
             
        
        
        
Answer:
The cell would lose the water inside it causing it to die. 
Explanation:
Water in cells moves towards the higher concentration of salt so if there is more on the outside the water would move on the outside causing it to die because it needs water. If it was the opposite and there was more salt inside more water would go inside causing the cell to swell and virtually exploding and diluting parts of our body.
 
        
             
        
        
        
<span>the factor that will have the greater impact on a population is : D. Climate
Climate will determine the overall environent condition in a specific region, which will eventually determine which organisms can survive there.

It results from the composition of the cell membrane. The cell membrane consists of a phospholipid bilayer, which have hydrophilic heads and hydrophobic tails. Hope this helps! :)
