Answer:
Please find the diagram attached and explanation below.
Explanation:
Mitosis is a type of cell division that forms two genetically identical cells. It involves four stages viz; prophase, metaphase, anaphase, and telophase.
Considering a diploid (2n) cell with four (4) number of chromosomes.
Prophase- four duplicated chromosomes condense and pair up.
Metaphase- four chromosomes line up at the cell plate or equator in order to get separated.
Anaphase- the sister chromatids are pulled apart by the spindle microtubules
Telophase: the chromosomes recoil and organelles form at opposite poles of the cell.
At the end of cytokinesis, which is division of the cytoplasm, four chromatids are present in each daughter cell. The chromatids becomes individual chromosomes that retain the diploid (2n) chromosome number of four.
Appalachian: A. Two continents colliding.
The Appalachian mountain range is an ancient example of a collision between two continental plates. Both plates have low density and little subduction occurs between them.
North American Cordillera: B. Terrane accretion
These form when two continents that collided bonded so tight that it forms a permanent land mass. If the continents would pull away from each other, the terrane stays intact.
Aleutian plate: D. Oceanic convergence
This is a type of convergence where one plate subducts beneath another plate. Between the two, the older plate is usually the one that subducts because it is usually more dense.
Andes mountain range: C. An oceanic plate and continental plate colliding.
In the collision between an oceanic and continental plate, the thinner and more dense oceanic plate subducts under the continental plate. The Andes mountain range was formed by the subduction of the Nazca Plate beneath the South american Plate.
A histone is a protein that interacts with DNA to coil it into a nucleosome.
A nucleosome is a small unit of DNA coiled around 8 histone proteins.
Therefore, the major difference is that a nucleosome is a small structure and histones are the proteins that help form the structure.
