Answer:

punctuated equilibrium

Explanation:

Punctuated equilibrium a model of evolution that explains evolutionary pattern as exhibited by fossils. According to punctuated equilibrium, a species undergoes a long period of no change or no evolution. This period of no change is called "stasis". And stasis is sometimes interrupted by a rapid phase of evolution. This pattern of evolution with long static phage interrupted by rapid phage of changes is called punctuated equilibrium.

DedPeter [7]

Nondisjunction could occur during - Anaphase ii

<h3>What is Nondisjunction ?</h3>

Nondisjunction occurs when the chromosomes do not separate. In this case, gametes are produced with an abnormal number of chromosomes. It is an abnormal number of chromosomes in all  cells called aneuploidy or in some cells called mosaicism.

Example ; Down's syndrome, Trisomy of autosomes.

Anaphase is the 3rd stage of cell division process specially after the metaphase in mitosis. In this step sister chromatids gets seperated from each other and pulls towards the cell's ending portion.

specially in Anaphase 2 chromatids splits at the centromere and pulled to the spindle fibres.

List the events of the sodium potassium pump in the correct sequence, starting at the TOP.
marishachu [46]

<u>Answer</u>:

<em>Sodium potassium pump works by following several steps. </em>

<u>Explanation</u>:

<em>1. Carrier protein binds three molecules of Na+ </em>

<em>2. ATP is split, phosphate bonds to carrier. </em>

<em>3. Carrier protein changes shape, and deposits Na on the outside of the cell. </em>

<em>4. Carrier binds two molecules of K </em>

<em>5. Phosphate is released. </em>

<em>6. Potassium is released inside the cell </em>

Sodium -potassium pump is essential to maintain the concentration of sodium and potassium outside and inside the cell respectively.

It is the function of sodium potassium pump to transport sodium out of the cell and potassium inside of the cell against a concentration gradient.

<em>Thus it is an active transport mechanism. </em>
