Avery and DNA (page 289)

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.

ahrayia [7]

Answer:

a. they can fix carbon at the lower CO2 concentrations that develop when the stomata are closed

Explanation:

C4 plants are those that have the capacity to fix CO2 even when a tiny concentration of it is available.

Desert condition is characterized by dryness and strong heat with both condition capable of creating water stress in plant as a result of evapotranspiration. In order to reduce evapotranspiration rate, desert plants (most C4 plants) close their stomata during the day.

<em>Stomata closure limit the diffusion of CO2 into desert plants and the small concentration of CO2 that results is utilized by a special enzyme in the plants.</em>

The correct option is a.
