Moon. The force of the moon constantly pulls the ocean and pushes the ocean.
Answer:
Secondary level of protein structure
Explanation:
The proteins are formed of the monomer units called amino acids which bond with each other via peptide bond and form a linear peptide structure called the primary level structure of the protein.
The proteins to perform several functions in a cell undergoes structural conformation and attain the helical form called alpha helix due to the involvement of alpha carbon in bond formation and a pleated sheet called beta-pleated sheet due to the involvement of beta carbon. These structures are known as a secondary level of protein structure.
Thus, a Secondary level of protein structure is the correct answer.
Interferons
Virally infected cells produce and release small proteins called interferons, which play a role in immune protection against viruses.
<h3>What are Interferons ?</h3>
Interferons prevent replication of viruses, by directly interfering with their ability to replicate within an infected cell.
- They also act as signalling molecules that allow infected cells to warn nearby cells of a viral presence – this signal makes neighbouring cells increase the numbers of MHC class I molecules upon their surfaces
- So that T cells surveying the area can identify and eliminate the viral infection.

Answer – B (crepuscular activity)
The adaptation of the California quail to live in the
chaparral biome is by crepuscular activity. This means that unlike nocturnal
animals that are most active in the night and diurnal animals that are most
active in the day, the California quail is most<span> active at dawn and dusk</span>
