Very, very rare. Uranium used in power plants is typically only 3% U-235 (the explosive stuff), while bomb-grade uranium is nearly pure U-235. Simply, the concentration of U-235 in reactor-grade uranium is too small to start a chain reaction and detonate like a bomb.
1. Whorls
2. Organs
3. Symmetry
<u>Explanation:</u>
Some important traits that influence the reproductive success of a flower include: the presence or absence of whorls, the fusion of organs to one another, and the overall symmetry of flowers.
In the process of reproduction in plants, the male and female gametes are produced and transfer of the male gametes to the female ovules occurs. This process is called as pollination. After pollination occurs, fertilization happens and the ovules grow into seeds within a fruit
Floral zygomorphy confers a reproductive advantage to rare plants" as a result of the enhanced pollination efficiency.
<span>Positive feedback</span><span>
There are two types of feedback mechanisms
Positive feedback heightens the intensity
Negative feedback lowers the intensity
These all serve to maintain homeostasis. Homeostasis is the state where the internal and external part of the body maintains and establishes balance and equilibrium. </span>
Answer:
Promoter is located upstream and terminator is located downstream relative to the transcription start site.
Explanation:
Transcription start site is the site from where the transcription starts which is denoted by +1. The sequence of nucleotides which is present backword to them called upstream sequence and nucleotide sequence which is present in the forward direction of transcription start site are called downstream sequence.
Promoter sequences are present upstream to the transcription start site and are denoted with a minus sign and terminator sequence is present downstream to the transcription start site.
Airborne is the most common.
