Mitosis is when a DNA error, aka mutation, occurs in a body cell. When cells divide, it needs a copy of the DNA. During DNA replication, that error can cause the instructions for building proteins to differ. The change can not affect offspring. Meiosis is the same situation, but in sex cells. This can be transferred to offspring.
<span>The question says,'the orange colour of carrot roots and marigold flowers comes from cell bodies known as chromoplasts. The statement is true. Chromoplasts are coloured plastids, they usually contain a yellow or orange pigment. They can be found in roots, leaves, fruits and ageing leaves and are responsible for the distinctive colours of these plant parts.</span>

Answer:
The correct answer is option c. "The apparent value of KM increases with a competitive inhibitor, while it remains unchanged with a noncompetitive inhibitor".
Explanation:
The KM value in an enzymatic reaction is defined as the substrate concentration at which the half of the enzyme molecules are binding with the substrate. A way to distinguish between a competitive and noncompetitive inhibition is that the apparent value of KM increases with a competitive inhibitor, while it remains unchanged with a noncompetitive inhibitor. A competitive inhibitor would make that a higher concentration of substrate is needed, while a noncompetitive inhibitor does not change KM since the inhibitor binds to a site of the enzyme different from the active site.
