Answer:
As I think second option is the correct one.
Explanation:
The myofibrils are made up of thick and thin myofilaments, which help give the muscle its striped appearance. The thick filaments are composed of myosin, and the thin filaments are predominantly actin, along with two other muscle proteins, tropomyosin and troponin.
Answer:
Cell theory refers to the idea that cells are the basic unit of structure in every living thing. Development of this theory during the mid 17th century was made possible by advances in microscopy. This theory is one of the foundations of biology.
<em><u>Plants</u></em> : plants are generally <em><u>autotropic</u></em> living organisms, that prepare their own food by using simple substances through <em><u>photosynthesis</u></em>,
eg. maple, bamboo, etc.
<em><u>Consumers</u></em>: these are living organisms that doesn't produce their own food and depends upon <em><u>producers</u></em> and other <em><u>consumers</u></em> for food.
eg. Human, rat, etc
<em><u>decomposers</u></em> : these are living organisms that break down the <em><u>dead</u></em> and <em><u>decaying</u></em> body of organisms to obtain their food,
eg. bacteria, mushrooms, etc
<em><u>producers</u></em> : these are living organisms that produce their own food through process of <em><u>photosynthesis</u></em>.
eg. plants, cyano bacteria, etc
The chemical reaction could be vary with the condition but the nuclear decay rate is constant, here the option A is the right option.
