Answer is anaphase

When a dividing eukaryotic cell is treated with a mitotic inhibitor drug, the drug disrupts microtubules. Microtubules are the structures that pull the chromosomes apart when a cell divides. The drug inhibits shortening of spindle microtubules during anaphase stage of mitosis. As a result cell division stops at anaphase stage. Mitotic inhibitors are used in cancer treatment preventing cell from division.

I believe the correct answer is the anaphase of M stage also called Mitosis

<h2>Explanation:</h2>

The cell cycle of eukaryotes has 4 stages; G1, S, G2 and M phases. It is during the M phase of the cell cycle that there is shortening of the microtubules to pull the separate single chromatids towards different poles so that the cell can undergo cytokinesis (division of the cytoplasm).

<h2>Further Explanation:</h2>

Before the cell cycle starts, the cell is usually at rest in a neglidgible G0 phase. It then enters the G1 phase which lasts for around 4 hours. The cell also rests here, prepares and increases the number of organelles. The cell is also checked for any inconsistencies and it does not proceed if errors are found in the DNA. It then enters the S phase where it lasts for around 8 hours and there is doubling of chromosomes in the cell. DNA synthesi occurs. It then proceeds to the G2 phase where again it is checked for any errors and there is increase in organelles.

It is in the M or Mitosis phase of where the cell is considered to be truly dividing. It starts with the prophase stage where the cell prepares for the upcoming division. The chromatin condenses, the nuclear envelope disintergrates and the nucleolus disappears. The spindles begin to disappear in preparation for the next stage of Metaphase. In this stage, the chromatins that had previously been condensed line the equator due to a pull force by kinetochore fibers. Their centromeres then align exactly at the center of the cell. This is the shortest phase of the cycle. Anaphase is the next stage and in this stage, the sister chromatids are pulled on opposite poles by the spindle fibers/microtubules. It is in this stagethat cancer drugs target the cell division by stopping the shortening of these microtubules that pull the chromatins towards different poles. In the last stage called Telophase, the cell is essentially divided and a nuclear envelope forms around each set of chromatin materials on the opposite sides. The cell then undergoes cytokinesis where the cytoplasm pinches and separates forming 2 new daughter cells completing the cell cycle. The cell lasts in this M stage for 11 hours. It enters the G1 phase afresh where it rests and prepares for the next cycle.

Answer: Light Refraction

Explanation:

Light rays travel in straight lines. When they strike an opaque surface, the rays bounce, and light is reflected back to your eye so that you see an image. When light strikes a transparent object, some of the light passes through. If that light strikes the object straight on, it continues to travel in a straight line. If the light enters the transparent object at an angle, though, it changes direction, bending.This bending of light is called refraction. Refraction occurs because light entering an object slows down. When it enters at an angle, one side of the light ray enters before the other, slowing down first.Looking from above, an object under water appears larger than it does in air. It's not that the image the light gave our eyes is bigger. It's that the image is actually closer to our eyes, since the light is not passing straight down, but is instead bending relative to the water's surface. Light passing straight down would be perpendicular to the water's surface, like the vertical line on the letter T.

According to the pedigree chart, which statement MUST be true?
dem82 [27]

Answer:

<h3>A) Only Male offspring can inherit the disease. </h3>

Explanation:

As per the pedigree chart, only the males are shown as affected by the disease. Thus, it must be a sex-chromosomal inheritance, expressed in the Y chromosome or the male chromosome.  

As the females in the family are unaffected, hence the mother in the original parental generation cannot be a carrier.

It is likely that the father from the original parental generation might be the carrier.

As there are affected individuals in both the generation after the original parental generation ( the last generation having two more affected males), the statement that the chances of inheriting the decease with each successive generation is not true.

HELP ILL MAKE YOU A BRAINLEST <br><br> CREATE A STORY OF THE MOON AFFECTING WILDLIFE
Vesnalui [34]
The moon affects wildlife because of its three profound influences on Earth. Time, light, and tide. For many animals, (mainly birds) the moon is essential for migration and navigation. Also, lions hunt the best during the darkest nights of the lunar month. Wildebeests and other prey of lions learn to avoid going out during dark nights to stay safe. Animals learn different things with the moon, whether it be safety, when to reproduce, or when to migrate.

I’m not sure if this is what you’re looking for, but these are some key points you could use in your story if you build around it. Good luck!

The process of translation is responsible for producing which type of molecule?
agasfer [191]

Answer:

The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in the ribosome decoding center to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.
