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.

You are a molecule of CO2. Write your autobiography. Tell how you started at glucose and ended where you are today as carbon dio
statuscvo [17]

Answer:

I started out as glucose, got converted to pyruvate, after which I got oxidised by Oxygen to become CO2

Explanation:

My name is CO2, and I started out as glucose from pure honey. I got eaten by a little child when I was two weeks old, and I had to go through the dreadful process of aerobic respiration in the child's body.

My glucose molecules were broken down into pyruvate, and I stayed that way  for a while, as I made my way to the mitochondria of the child's cells.  Once I got to the mitochondria, I met my old friend oxygen, who reacted with me to turn me into the molecule I am today - C02.

If you want to know how I escaped the child's body, that's easy - I simply snuck out his nose while he was breathing one cold dark night.
