Answer:
transformation
Explanation:
Transformation is one of the three methods of genetic recombinant in bacteria. The other two are transduction and conjugation. Transformation occurs when the bacterial cells take up the DNA and which in turn changes their phenotype.
Transformation requires that there should not be any cell to cell contact. In the experiments performed by Griffith, the heat-killed virulent S strains were mixed with live R strains. The R strain took the DNA of heat-killed S strains which in turn converted them into the virulent strains. Since this horizontal gene transfer did not include any cell-to-cell contact, he called the process transformation.
Answer:
The process that does not require oxygen is fermentation.
Explanation:
Fermentation is an alternative route of cellular respiration for obtaining energy, in the absence of oxygen. In aerobic respiration, oxygen is the acceptor of electrons from NADH but, in anaerobic respiration, the electron acceptor is an organic compound.
The fermentation process does not occur in the mitochondria nor does it involve the electron transport chain, and has a low energy yield at the end of the process.
With respect to the other options:
- <em>The </em><em><u>electron transport chain</u></em><em> and the </em><em><u>Krebs cycle</u></em><em> occur in the presence of oxygen.</em>
Answer:
E. Coal
Explanation:
Coal produces more pollution than any other energy source. Burning coal leads to soot, smog, acid rain, global warming, and carbon emissions.

HOPE THIS HELPED!!!
<span>A person's oxygen dispersal into the bloodstream from the lungs drops about 4 percent every decade. This happens because of decrease in organ reserve due to aging.</span>
Answer:
Ciliated cells are adapted in the respiratory tract to form an epithelial lining of coordinated metachronal ciliary activity that provides the propelling force for the transport of mucus along the airways.
