Please answer all seven multiple-choice questions
Explanation / Answer
1. Option C - Transformation and gene gun. All other options are not completely correct in viral mediated it is only Adenovirus not HIV.
2. All the above - all the molecules diffuse across phospho- lipid bilayer
3. Option D - a and b. Yeast is eukaryotic unicellular organism under the class fungi which ferments under low oxygen concentration.
4. Binary fission - Gene transfer from parent to offspring
5. Option A- Resistant bacteria which can live for hundred years
6. All the above - All the said statements are characters of cyanobacteria
7. Option b - Prions are harder to kill followed by endospores, Mycobacteria and fungi.
