This happens because taproot formation is impossible, so trees developed shallow root beds.
Permafrost is soil that has a temperature below 0 °C (for about two years) and forms a solid matrix which can extend to a depth of hundreds of meters. Because of this structure the permafrost prevents trees from developing deep root systems. As a consequence, the shallow root bed of trees such as black spruce, causes them to lean or even fall.
Answer:
a. The smaller protein will migrate (move) faster relative to the larger protein in SDS-PAGE but slower in gel filtration.
Explanation:
Gel filtration chromatography is a technique of chromatography in which particles facilitate separation based on molecular size. The larger protein come out of the column and form gel permeation chromatograph. The smaller proteins move faster to migrate from the column.

The cervix or cervix uteri refers to the lower portion of the uterus in the human female reproductive system. The openings are called the internal orifice and the external orifice of the uterus.
The internal orifice or internal os refers to the upper terminal of the cervix, which opens into the uterus. On the other hand, the external orifice refers to the terminal of the cervix, which opens into the vagina.
