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:
C
Explanation:
most of them drink their blood
Answer:
Smoke-induced oxidative stress limited the oxygen-carrying capacity of the previous red blood cells
Explanation:
The red blood cell (RBC) contains hemoglobin which helps in the transport of oxygen. However, the Jane's smoking must have induced oxidative stress to the cells of her body including RBC, thus compromising it's oxygen-carrying capacity.
Hence Jane's body increased RBC count in order to maintain oxygen supply to all cells of her body.
Answer:
Use 400 x in order to study the structure clearly.
Explanation:
Cell structures could be clearly identified when magnify the microscope about 400 x by using a compound microscope. Due to high magnification power of compound microscope, the individual is able to see different structures that are present in cells. while by using lower magnification, the individual is unable to see different structures clearly. So use high magnification in order to study the cell.
