Answer:
b. Cellular clock is the correct answer.
Explanation:
Cellular clock theory states that cells can divide a maximum of about 75 to 80 times, and that as we age our cells become less capable of dividing.
Cellular clock theory directs on the lifespan of organisms. As the many individual cells do not remain to reproduce continually, so this theory implies that aging of the cells is a result of their reproductive limitation and because of cellular aging.
Cellular clock theory is the theory Leonard Hayflick's that describes the cellular aging mechanism and it suggests that as the cell becomes aged it becomes less effective of dividing.
The answer would be m<span>ycoplasmas. These type of organisms are very unique, because their membrane lacks a cell wall.</span>
The answer to your question is supply invoice
Yes, that is true. Yellow and green colors are now the major colors of these fire engines due to our eye-sights. In the dark, red is one of the least visible colors so imagine what would happen if it was at night and you could barely see it. On the other hand, colors like yellow and green are spotted more easily and raise awareness in a proper and eye-catching way.

Answer:
Enzymes are proteins in composition which are a very essential component of the metabolic reactions in the living organisms.
The properties of enzymes allow the enzymes to be used as a reaction catalyst which increases the speed of the reaction.
The enzymes lower the threshold energy of the chemical reaction and thus increases the rate of reaction.
The enzyme catalyses very complex reactions like a breakdown of complex biomolecules as well as the formation of complex biomolecules.
The active sites are present on the enzymes which bind the substrate molecule and increases the pace of reaction.
