Answer:
Mitosis is the cell division in which a single is divided into the two daughter cells. The genetic constituent remain same in this type of division and known as equational division.
Four phases of mitosis are metaphase, prophase, anaphase and telophase. Prophase is the first stage in which the nuclear envelope disintegrates. The cohesion joins the sister chromatid together. In metaphase stage the chromosomes gets arranged at the metaphase plate and microtubules are attached to the kinetochores. The cohesin break downs and the sister chromatid moves towards the opposite poles at the anaphase stage. The telophase stage results in the formation o the nuclear envelope and spindle microtubules disassemble at this stage.
Answer:
La hay porque si bien la anatomía humana se basa simplemente en los humanos, la fisiología tiene que ver con todas las criaturas vivientes con diferentes tipos de partes del cuerpo.
Explanation:
Based on the given description above regarding birds and mammals that possess four-chambered hearts with fully divided pulmonary and systemic circulations, what makes the incomplete separation of circuits in these organisms advantageous is that the distribution of the blood flow can be adjusted whether the organism is breathing through its lungs or not. Hope this helps.
The enzyme helicase unwinds the double stranded DNA molecule. This enzyme is essential during the process DNA replication because it separates the double stranded DNA into single strands allowing each strand to be copied. The action of helicates sets up a replication folk and a replication bubble the enhances the first step of replication by DNA polymerase.
