Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated; and an M phase, in which mitosis partitions the genetic material and the cell divides.

 

<span><span>G1 phase. Metabolic changes prepare the cell for division. At a certain point - the restriction point - the cell is committed to division and moves into the S phase.</span><span>S phase. DNA synthesis replicates the genetic material. Each chromosome now consists of two sister chromatids.</span><span>G2 phase. Metabolic changes assemble the cytoplasmic materials necessary for mitosis and cytokinesis.</span><span>M phase. A nuclear division (mitosis) followed by a cell division (cytokinesis).</span></span>

The period between mitotic divisions - that is, G1, S and G2 - is known as interphase.

<span>Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell. Chromosomes replicated during the S phase are divided in such a way as to ensure that each daughter cell receives a copy of every chromosome. In actively dividing animal cells, the whole process takes about one hour.</span>

Which Of The Following Most Accurately describe the result of cell division without differentiation?
suter [353]
Hmm...,
      Well from what I'm getting, I feel like the cell would just be replication itself. Cell differentiation is the process by which a cell gets placed, or destined, to become a particular type of cell.
    So, if a cell was to go undergo cell division with out cell differentiation, this most likely means it is going under the DNA replication process, AK.A- splitting the mother cell to create daughter cells.

A _____ is used to reveal the detailed internal structure of a cell.
gladu [14]

Answer:

The correct answer will be- Transmission electron microscope

Explanation:

A Microscope is an optical instrument designed to view the microscopic things which could be living or non-living around us.

The internal structure of a microscope can be viewed by a light microscope mainly dark-field microscope but a detailed structure of a microscope can be viewed by an electron microscope mainly a transmission electron microscope.

The transmission electron microscope studies the internals structure of the cell by creating the 2D images by passing the beam of electrons through the specimen.

Thus, a transmission electron microscope is the correct answer.

Which term describes the deep flat part of the ocean floor?
bulgar [2K]

The correct answer is abyssal plain.  

The ocean basin or the abyssal plain refers to the flat region of the ocean floor. It is enveloped with mud, sand, and animal and plant remain. Situated on this flat plain are underwater mountains known as seamounts, which are produced by volcanic eruptions.  

The challenger deep, in the southern terminal of the Mariana Trench is the deepest point in the ocean.
