Answer:
A comparison of the three different forms of double-stranded DNA reveals that <u>Z-DNA</u> has the largest pitch per turn of the helix, whereas <u>A-DNA</u> has the widest diameter.
Im afraid the answer is no there is a chemical in turtles saliva that does not allow you to physically drink orange juice if you do you will die.
Answer:
Because humans couldn’t see outside of earth. Gailieo Galilei used his telescope to prove this was wrong ultimately.

it was debunked till the 16th century. Scientists observations and knowledge had advanced too far for the geocentric model to explain them.
I looked like the sun was moving from earth but it really earth thats moving around the sun. The parallax is effect helped explain this.
Answer: depolarization; hyperpolarization
Explanation:
At resting potential (absence of stimulus), the cell membrane of a neuron is said to be polarized with a net negative charge within due to more potassium (K+) ions present than sodium (Na+) ions.
However, an impressed stimuli reverses the ions content as K+ ions flows out and quickly replaced by Na+ ions, resulting in a decrease in membrane potential and a more positive cell membrane. Thus, depolarization occurs.
An increase in the membrane potential (so that it becomes more negative) is called hyperpolarization.
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.
