There were many factors that affected people who lived in the Great Plains during the Dust Bowl era. What was the main factor th

cupoosta [38]

Answer: The Dust Bowl was caused by several economic and agricultural factors, including federal land policies, changes in regional weather, farm economics and other cultural factors. After the Civil War, a series of federal land acts coaxed pioneers westward by incentivizing farming in the Great Plains.

Explanation:

1) Manifest Destiny: The US Government wanted settlers to move onto the Plains as they needed the land to be settled and farmed and for communities and towns to grow up and expand. This was needed if the USA was to be a rich and successful country. The government therefore promoted the idea of Manifest Destiny.

Why is it necessary for DNA to replicate as the first step in mitosis?

Zepler [3.9K]

DNA is a macromolecule composed of nucleotides which carry the genetic instructions used in the growth, development, functioning and reproduction of the cell. One of the most important characteristics of DNA is its ability to make several copies of it (to be copied via the process of replication). When the cell divides into two it must carry each copy of DNA into the divided cells. Through replication, the DNA transfers the information necessary for creating an exact copy of it in the new daughter cell. The transfer of the DNA to the next generation of cells is essential for the function of the whole organism.

DNA replication will make the organism to reproduce the genetic code and transfer it to the next generation (through the reproduction) and thus, to continue the species.

J) type of adhesive junction containing actin microfilaments. Adherens junctions

K) specialized modifications of the cell membrane in which two cells come together in multicellular organisms. Cell junctions

L) point of cytoplasmic contact between two cells. Gap junction

M) anchors cytoskeleton of one cell with that of a neighboring cell. Adhesive junction

Explanation:

Connexin: is a transmembrane protein that forms the gap junctions, they are also called gap junctions proteins.

Hemidesmosome junctions: these types of junctions are in the epidermis, specifically between the epithelial cells and the basal lamina of the epidermis.

Plaque: they are part of the adherens junctions, they are fibrous proteins that are attached to certain points of the extracellular matrix.

Tight junctions: are junctions between two epithelia, they are very restrictive and do not allow the passage of soluble molecules creating a permeability barrier.

Desmosomes: are very strong cell to cell junctions on the lateral sides of plasma membranes. They are in tissues that are under mechanical stress, such as the cardiac muscle.

Connexons: is a pore made of six connexin proteins in a gap junction. Connexons are the ones that connect two cells in gap junctions.

Focal adhesions: They connect the extracellular matrix with the cell, regulatory signs and mechanical force is transmitted through them.

Tonofilaments: tonofilaments are the ones that are associated with a plaque in adherens junctions, they are in epithelial tissues.

Adherens junctions: are cell to cell junctions where the cytoplasmatic face is connected to the actin cytoskeleton. They appear as spots forming the plaque or as zonula adherens, which are actin bands around the cell.

Cell junctions are protein complexes that connect two cells that are next to each other or a cell with the extracellular matrix. They have a lot of functions, such as pas information from cell to cell, or the exterior, form a barrier, synchronize cells, etc.

Gap junctions: are connections between the cytoplasm of two cells, molecules and, ions pass directly from one cell to the other.
