Answer:
The correct answer is - 130 kDa, 82 kDa, 45 KDa.
Explanation:
In the question given is there are 4 subunits in protein omicron in which two subunits are - 65 kDa and the other two subunits are - 85 kDa and 45 kDa.
So the size band would be in absence of beta-mercaptoethanol which is very essential to break down disulfide bonds that held together these subunits:
Size band = 65 KDa + 65 KDa
= 130 KDa (one band) (
65+65=130),
82, 45 as without beta mercaptoethanol disulfide bond is not broken
.
Thus, the correct answer is - 130 kDa, 82 kDa, 45 KDa.

Answer:
They do not make their own membranes.
They have, at most, one or a few enzymes.
They do not have both DNA and RNA.
They do not have cytoplasm or ribosomes.
They are much smaller than most cells.
They cannot replicate on their own.
Explanation:
Viruses are obligate parasites and are considered acellular since they do not have the basic cell structure. Being an acellular structure, viruses lack membranes, organelles, ribosomes, cytoplasm, etc. Viruses lack their own metabolic machinery, that is, they do not have their own enzymes to replicate themselves. They enter the host cells and use the enzymes of host cells to replicate themselves. Viruses have a genome (either DNA or RNA) that is surrounded by a protein coat.
On the other hand, cells are much larger than viruses. Cells have a cell membrane that encloses liquid cytosol in which various organelles such as ribosomes are suspended. Cells have all the required enzymes for metabolism and can make their own membranes. They can replicate themselves. DNA in a cell is present in the nucleus while RNA is present in both nucleus and cytoplasm.
<h2>Answer is option "A"</h2>
Explanation:
- The concept of actor-observer bias states that the causes of behaviors and events in our lives are motivated by attribution. Attribution is an inference that we make about our behaviors and the behaviors of others. The attributions we make depend directly on whether we are the actor or the observer.
- The actor-observer difference inclination will be progressively articulated in circumstances where the results are negative. For instance, in a circumstance where an individual encounters something negative, the individual will regularly accuse the circumstance or conditions. When something antagonistic happens to someone else, individuals will frequently censure the person for their own decisions, practices, and activities.
- Hence, the right answer is option A "actor-observer perspective".
