The muscles of respiration are muscles that contribute to exhalation and inhalation by causing the contraction and expansion of the thoracic cavity. However, diaphragm is the main muscle of breathing while intercostal muscles is one of the most important muscles for respiration. Intercostal muscles function by manipulating the width of the rib cage and they are attached between the ribs.

Plant cells form a cleavage furrow or indentation of membrane between new daughter cells.

<h2>Mitosis Process</h2>

Explanation:

Plant cells and animal cells undergo the same cellular processes during mitosis.

The centrioles absent in the plant.
Animals cells have centrioles, to what delivers the shaft strands is one of the differences among plant and creature mitosis.
The periods of mitosis and goes on in each stage is the equivalent aside from when it comes to how cytokinesis is practiced.
<em>Plant cells separate the cytoplasm between the two new cores by framing a cell plate (new cell wall)between the cores.</em>
Animals cells achieve this by shaping a cleavage wrinkle which is a squeezing in at the center of the<em> </em><em>cell until two new cells have been framed with cytoplasm and organelles for each new nuclei.</em>

Mistakes can happen during DNA replication, and if they are not repaired it can result in a mutation. Certain mutations can lead

polet [3.4K]

Mutations result either from errors in DNA replication or from the damaging effects of mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides. All cells possess DNA-repair enzymes that attempt to minimize the number of mutations that occur
