Answer:
A) actin and myosin is a correct answer.
Explanation:
- Myofibrils are the contractile fiber and they are made of actin and myosin.
- Myofibrils are made of thick myofilaments and thin myofilaments.
- Thick myofilaments are made up of myosin whereas thin myofilaments are composed of actin.
- The functional unit of muscle is Myofibrils and contraction of muscle occurs due to myofibril, when the filaments actin and myosin interact with each other.
Thus Myofibrils are made primarily of (A) actin and myosin.
Constipation and diarrhea, are both caused by a similar thing. Constipation is caused whenever there is too much buildup of food, or other food based material in the intestines. Usually this passes itself, yet constipation can also cause diarrhea through a bowel movement.
What area of a cell is the location of rRNA synthesis and is also in charge of ribosomal subunit assemblage?
What is rRNA?
Ribosomal RNA (rRNA), a molecule in cells that is transferred to the cytoplasm and is a component of the protein-producing organelle known as a ribosome, aids in the conversion of messenger RNA (mRNA) into protein. rRNA, mRNA, and transfer RNA are the three main forms of RNA found in cells (tRNA).
Nucleolus area of a cell is the location of rRNA synthesis and is also in charge of ribosomal subunit assemblage.

Answer:
The meaningful differences between organisms in a population are genetic. Variations in the genome of members of a population arise through mutation. Occasionally, a mutation occurs in an individual that is beneficial, that helps that organism be better able to survive and repoduce in its current environment.
