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.
<h3><u>Answer;</u></h3>
<em>Centrioles </em>
<h3><u>Explanation;</u></h3>
- <em><u>Centrioles</u></em> are organelles that are only found in animal cells.
- <u><em>Centrioles are important organelles that functions by helping the process of cell division in animal cells.</em></u> This is by helping the formation of spindle fibers whose role is to separate chromosomes during cell division.
- Additionally, <em><u>centrioles also play a very important role in celiogenesis, the formation of cilia and flagella on the surface of cells.</u></em> The cilia and flagella enhance the movement of cells.
