A cell with 80 chromosomes undergoes mitosis. How many chromosomes are found in the daughter cells? How many daughter cells are
Natalka [10]

Answer:

1. 80 chromosomes are found in each of the daughter cells. 2. Two daughter cells are produced. 3. The daughter cells are identical to each other.

Explanation:

Mitosis is simply a process of cell division whereby two daughter cells that are genetically identical are produced from a single parent cell. A cell having 80 chromosomes would undergo Mitosis through these various stages:

Interphase: This can be referred to as the rest phase between cell division when mature enough for reproduction. This is a preparatory stage where DNA is duplicated and ready for the division of chromosomes

Prophase: This stage marks the beginning mitosis of the cell with 80 chromosomes. The chromatin threads start a coiling process in which the chromosomes become condensed to enable easy distribution to daughter cells without tangling.  

Prometaphase: This phase commences toward the end of the prophase, where the nuclear envelop breaks down. The chromosomes move toward to the center of the cell.

Metaphase: At this stage, the duplicated chromosomes line up on the mid plane or equator of the cell. During this stage, each chromatid is condensed completely and appears thick and distinct.

Anaphase: At this stage, the chromosomes move toward the poles as each replicated copies of the DNA of the cell ends up on either side of the cell. What we would have here at this stage is an entirely two new sister chromatid having 80 chromosomes. Cytokinesis begins towards the end of this stage as the parent cell cytoplasm divides which also continues at telophase.

Telophase: This is the final phase of Mitosis where two separate nuclei are formed and Cytokinesis takes place to complete the division of the cell to form two daughter cells having the same number of chromosomes. These cells are genetically identical to the original parent cell.

How does phospholipid structure relate to the selective permeability of the plasma membrane? a critical feature of the plasma me
Katen [24]
The structure of plasma membrane makes it selectively permeable allowing it to regulate the passage of substances into and out of the cell. Small nonpolar molecules can easily across the phospholipid bilayer of plasma membrane because it is hydrophobic. Polar molecules and ion cannot easily across the hydrophobic portion of plasma membrane because it is hydrophilic. Polar molecules and ions usually across the plasma membrane with the help of transport proteins.

A GeoChart is a tool used to visualize data on a map. The size of the circular
7nadin3 [17]

Explanation:

We know that the larger the circle, the more large the diameter of the circle the more the quantity being studied.

We can clearly see that the South eastern coast of Australia has more number of people diagnosed with cancer.

The South western and the Northern part also records a sizable amount of skin cancer cases.

  • In the middle part of the map where the circles are small, the number of people diagnosed  with cancer is very low
  • Other areas without the circle did not record any case of skin cancer.
