<span>Since muscle contraction depends on interactions between actin, myosion and some intermediate molecules, the primary protein structure of such proteins and their spatial conformation are fundamental for their functioning. For example, actin and myosin, both filamentous proteins that slide past each other or troponin/tropomyosin interactions that blocks the binding of myosin to actin.</span>
Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm. Bacteria can do this through several mechanisms.

Answer:
C, the DNA in a Eukaryotic cell is in the nucleus
I think local winds is like somewhere where it is usually windy with high pressures. For example see breezes, land breezes, and etc.
Hope this helps!
Cells specialize (have different functions/organelle counts, etc) when they selectively activate (turn on) certain genes in their copies of DNA in the cell nucleus.
