Answer:
The answer is "PK1 activates PK2"
Explanation:
All enzymes were required again for the transmission of a signal. If Pk1 is continuously active, pk2 will no longer be required, as per my theory, can trigger pk1, therefore the cells were if they amplify the message even when they're not active. But since both enzymes require regular copies together for transduction, pk2 is simple and pk1 requires to also be activated.

Answer: The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg called ovules. The stamen is made up of two parts: the anther and filament. The anther produces pollen (male reproductive cells). The filament holds the anther up. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary.
Explanation:
Mutations can be caused by ultraviolet radiations from the sun or is the DNA copies itself during cell division. However, acquired mutations in somatic cells (cells other than sperm and eggs) cannot be passed to the offspring. When mutations occur in reproductive cells and are called germ line mutations. A single germ line can have a range of defects.
