<h2>Development of Plant Needles</h2>
Explanation:
- Seed of pitch pine treated with colchicine delivered tetraploid seedlings which had thick and sporadic needles and less fortunate tallness and diameter growth than ordinary seedlings.
-
In test of colchicine-initiated polyploidy in pines, researcher found that a significant number of the polyploid plants returned to a diploid development in light of the fact that the polyploid cells partitioned at a more slow rate and were overwhelmed by the more quickly developing diploid cells which encompassed them.
-
The primary needles of both diploid and polyploid plants were more effective at low light intensity than secondary needles, and they had lower compensation points.
Answer:
150 - 300 bp
Explanation:
Micrococcal nuclease, indistinctly from the time of treatment and in average organisms, will realize the cuts on DNA o RNA zones rich in AT or AU. It is not a specific endonuclease.
Even so, the mean size of the expected fragments will have between 150 bp and 300 bp.

Answer:
winter
Explanation:
On this image, we can see the Earth being tilted away by 23.5 degrees from the Sun. This tilting puts the Northern Hemisphere in a situation where it is the one that is tilted away from the Sun, thus it will receive less sunlight, as well as less direct sunlight. That will cause lower temperatures on the Northern Hemisphere, thus the winter season will start, and it will last for around three months, at least at the mid-latitude zones. On the other side, the Southern Hemisphere is more exposed to the Sun during this tilting, so t receives more sunlight, and more direct sunlight, resulting in summer in this half of the planet.
