- Let's review. Mitosis is the process of dividing body cells and their nuclei. This results in identical cells, so it helps you grow and repair damage when you do things like scrape your knee. Your cells are not always dividing.

What is facilitated diffusion?   Facilitated diffusion (or facilitated transport) is a process of diffusion, a form of passive transport facilitated by transport proteins. Facilitated diffusion is the s … pontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane transport proteins.

- Answers. Best Answer: Mitosis is the process of cell division. The cell equator, or equatorial plate, is when the nucleus has broken down, and the chromosomes are lengthening, and forming a line in the middle of the cell. This happend during Metaphase. This line is called the cell equator.he cell equator, or equatorial plate, is when the nucleus has broken down, and the chromosomes are lengthening, and forming a line in the middle of the cell.

- Facilitated diffusion is another type of passive transport in which substances travel through the cell membrane. One substance that undergoes facilitated diffusion is glucose. Glucose, like water, relies on a special carrier protein.

mitosis Mitosis definition, the usual method of cell division, characterized typically by the resolving of the chromatin of the nucleus into a threadlike form, which condenses into chromosomes, each of which separates longitudinally into two parts, one part of each chromosome being retained in each of two new cells resulting from the original cell.

Section 19.5 Microtubule Dynamics and Motor Proteins during Mitosis The Mitotic Apparatus Is a Microtubule Machine for Separating Chromosomes. The mitotic apparatus has no fixed structure: it is constantly changing during mitosis (Figure 19-35). For one brief moment at metaphase, however, when the chromosomes are aligned at the equator of the cell, the mitotic apparatus appears static.

Mitosis In cell biology, mitosis is a part of the cell cycle when replicated chromosomes are separated into two new nuclei. In general, mitosis is preceded by the S stage of interphase and is often accompanied or followed by cytokinesis, which divides the cytoplasm, organelles and cell membrane into two new cells containing roughly equal shares of these cellular components. Mitosis and cytokinesis together define the mitotic phase of an animal cell cycle—the division of the mother cell into two ...

Mitosis Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word mitosis means threads, and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.rophase is the first stage in mitosis, occurring after the conclusion of the G 2 portion of interphase. During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase.

- Airflow Meter. An airflow meter measures air velocity as well as air pressure. Depending on the type of application, the airflow meter is made as a hot-wire airflow meter, a vane airflow meter, a cup anemometer, a Pitot tube air flow meter or a pocket weather flow meter, all of which can measure air velocity as well as air pressure. Some can even detect the wind direction.

The Stages of Mitosis Simplified Overview of the Role of Mitosis. In the grand scheme of cellular life the stages of mitosis is simply responsible for the regeneration of cells in the exact form as its predecessor or parent cell. Thanks to mitosis mammals are able to continuously regenerate skin, hair, red blood cells, and repair wounds.

Mitosis and cytokinesis in plants and animal cells? Mitosis is the process by which a cell duplicates its genetic information (DNA), in order to generate two, identical, daughter cells. It is generally followed immediately by cytokinesis which divides the cytoplasm and cell membrane.

Difference between facilitated diffusion and secondary active transport in cells 3 Answers 3. Facilitated diffusion is a passive process in which membrane channels mediate the transport of polar, or big molecules that are not solvable in the cell membrane. Co-transport, on the other hand, is active transport, as it depends on the electrochemical gradient of ions across the cell's membrane, particularly Na+.

- Before the cell enters the mitosis sequence, it first undergoes a DNA synthesis (or S) phase where each chromosome is duplicated to produce an identical pair of sister chromatids joined together by a specific DNA sequence known as a centromere.

CELL CYCLE Regarding mitotic chromosome structure, centromeres represent a constricted region of the chromosome (often referred to as the primary constriction) where two identical sister chromatids are most closely in contact.

Built-in Controls in Mitosis One of the main controls is called contact inhibition. When a few cells are placed in a dish in nutrient broth, the cells will divide until they have covered the bottom of the dish, then when they are all touching each other, cell division stops.

- Mitosis and Meiosis describes the process by which the body prepares cells to participate in either asexual or sexual reproduction to make an entire organism. Examples of Mitosis and Meiosis Mitosis is the reproduction of skin, heart, stomach, cheek, hair etc. cells. These cells are Autosomal cells. This is also a form of Asexual reproduction, where one organism or cell reproduces itself. Some organisms that reproduce asexually are hydra, bacteria, and single celled organisms.

Difference Between Simple Diffusion and Facilitated Diffusion Facilitated diffusion is also called facilitated transport or passive mediated transport. It is a process in which the type of transport is passive that is enabled by proteins. Diffusion by this type is also spontaneous, unstructured, or unplanned passage of molecules or ions in a membrane through the aid of proteins.

What are the similarities between mitosis and meiosis? Mitosis is the standard way that a nucleus divides, generating a replica of itself. Meiosis is a modified mitosis, that carries one round of genome duplication followed by two rounds of karyokinesis (physical split of one nucleus into two nucleus). The total genome content is doubled and then split in four parts, producing 4 cells with half the genomic content of the original.
