Answer:
Explanation:
1)Pfr/Pr
2) Pr
3)far-red
Explanation:
The leaves at the top of a tree’s canopy are exposed to direct sunlight during the day, and their phytochromes will occur in a high *Pfr/Pr* ratio. Meanwhile, the leaves of the same tree at the bottom of the canopy are highly shaded during the day and will likely have a higher proportion of the * ( PHYTOCHROME )Pr *;form of phytochrome present due to exposure to a higher proportion of *FAR RED * light.
Plants make use of the phytochrome system to it's adjust growth based on the seasons. Through phytochrome plants is able to respond to the timing and duration of dark and light periods. At dawn, all the phytochrome molecules present in the leaved are converted to the active Pfr form until sunset this is because the sun is unfiltered, and unfiltered sunlight has high percentage of red light, but lower far-red light, with the help of phytochrome system , the plants is able to compare the length of dark periods over several days.
According to <em>Newton's Second Law of Motion</em>, force is defined as mass times acceleration. If the same car is accelerated to <u>60 mph</u> compared to 30 mph, the force will be <u>greater</u>.
Answer:
Please Provide more information, but generally you can use any measuring tools. If its volume, the formula is V = W * H * L
Explanation:
Answer:
positive pressure
Explanation:
Exhalation is a passive process during which the intercostal muscles and the diaphragm relax. The ribs move downward and inward, while the diaphragm rises. This movement causes the chest to decrease in size and positive pressure to build inside the chest cavity. The positive pressure pushes air out of the lungs.
A Punnett Square is a chart in which you cross two parents' offspring to figure out what traits their offspring may have. It helps give an estimate of the probability of the child having different attributes, such as eye color or hair color through the use of dominant and recessive alleles.
