There is some variation based on species of mouse.

Laboratory mouse has 40 while a deer mouse has 48 as examples.

Matching questions match each description with the appropriate phase of mitosis:

Hello!!
A: Anaphase — 1 chromatids move towards opposite poles. I always remember that “Ana” moves to different places on the sides of town. This is where the chromatids begin to move.
B: Telophase — 4 Cytokinesis may occur. Cytokinesis is the last and final step. The sister chromatids finish moving towards the poles and then cytokinesis occurs.
C: Metaphase — 3 Chromatids line up in the middle of the cell. I always remember since they line up in the middle, they “met” there.
D: Prophase — 2 and 5 Disintegration of the nuclear membrane and the spindle forms. Both of these have to happen first in order for the rest of the processes to occur.
**The order of mitosis goes prophase, prometaphase, Metaphase, Anaphase, Telophase, and Cytokinesis.**
For the bottom:
A: Algae 6 and 10. Both diatoms and kelps (plant related) are a part of the Algae general type.
B: Fungi 7 and 9. Deuteromycetes and Ascomycetes.
C: Protozoa 8. It is ciliates because they are a major group of Protozoa from cilia.
I hope I helped!! Have a great day!! :)

Evolution is change in a population over time and includes the gene pools of that population. How does biogeographic isolation a

MakcuM [25]

Answer:

Biogeographic isolation causes changes in gene pools that result from populations being separated.

Explanation:

Biogeographical isolation consists in the separation of a population by a geographical barrier, giving rise to <u>subpopulations</u>.

With isolation, the subpopulations start to suffer different pressures from the environment and consequently the selected genes in one subpopulation will be different from the other subpopulation.

Due to the biogeographic isolation, the two subpopulations will be prevented from crossing and the differences between them will become more and more accentuated, and with that the <u>subspecies</u> appear.

Over time, these subspecies may become so different from each other that reproduction between them becomes impossible.

When this happens, reproductive isolation occurs and, consequently, the emergence of new species. When speciation occurs due to geographic isolation, it is called allopatric speciation.

20. Interphase

21. Prophase

22. Interphase

Explanation:

The cell cycle is divided into two main divisions. The Interphase ad the M phase or the Mitotic phase.

Throughout Interphase, the cell is not dividing yet, but it is preparing to divide. It synthesizes the nutrients it will need, and grows in preparation to become two cells. This is actually the phase the cell spends the longest time.

Mitotic phase is when the cell starts to divide. It is separated into:

Prophase:

In this phase the chromosomes are condensed and mitotic spindles start to form. These spindles are made up of microtubules that will help later on to split the chromosomes. The nuclear membrane disappears so that the chromosomes will be free to move.

Metaphase

This phase is marked by the alignment of the chromosomes in the middle of the cell. They line up and you will find the asters at the opposite ends of the cell, where the microtubules stem from, attaching themselves to the center of the chromosomes, which we call the kinetochore.

Anaphase

In this phase you will see that the chromosomes are separated by the spindle fibers and are pulled at opposite ends of the cell. The cell then becomes longer by the other spindle fibers that are not attached to a chromosome.

Telophase

This phase is the end phase. The two sets of chromosomes are then enclosed by new nuclear membranes forming two nuclei and other cellular structures just as the cells are about to separate completely. As the two new cells move further apart, in plant cells a cell plate forms, dividing the two cells. The movement of the two cells splitting apart is called cytokinesis and it happens just as mitosis is about to end.

Attached is a picture of the cell cycle of a plant cell.
