In humans, there will be 46 chromosomes in each of the diploid cells after mitosis. Mitosis is the equational division which results in the formation of offsprings with same number of chromosomes as that of parents.
Mitosis is a type of cell division in which the chromosomal number remains constant from parents to the offsprings. It is therefore also known as Equational division.
Mitosis occurs in all the somatic cells of body. In this division, a parent cell divides to form two daughter cells with equal number of chromosomes. In a diploid (2n) cell, there are two sets of chromosomes whereas in a haploid (n) organism there is one set of chromosomes. In humans, the haploid set contains 23 chromosomes whereas diploid set contains 46 chromosomes (23 pairs).

Answer:
Anaphase of mitosis
Explanation:
Taxol: is a drug that prevents growth of cancer cells by interfering with the disassembling process of microtubules during the Anaphase of mitosis. The drug is able to bind to microtubules and freeze them.
Microtubules: are filamentous proteins and are made up of tubulin subunits. Microtubulesform part of the cell's cytokeleton which is vital for maintaining the shape of the cell and transportation of organelles and other molecules inside the cell.
Anaphaseof mitosis: microtubules from opposite poles of mitotic cells attached at the kinetochore of sister chromatids pull the each sister chromatid to opposite poles thus pulling them apart. The disassembling of the microtubules causes the sister chromatids to pull apart.
The mitotic phase specifically metaphase is of the most interest to a researcher studying Taxol because this drug halts the process of mitosis by preventing microtubules from depolymerizing.
If you were a researcher studying Taxol, you would be most interested in the cells found in the mitotic phase of the cell cycle. Taxol is a drug that disrupts mitosis by binding to the tubulin in microtubules and preventing their depolymerization, which effectively halts the process of mitosis in metaphase. This is because during metaphase, the chromosomes line up along the metaphase plate of the cell and the microtubules attach to the centromeres of the chromosomes, preparing to pull them apart during anaphase. Since Taxol prevents the microtubules from shortening, they cannot pull the chromosomes apart, thus cells treated with Taxol get stuck in metaphase.

Soils, like clay, absorb water quickly.
B)
Sinkholes collect water above the water table.
C)
Land with no slope lets water runoff at a fast rate.
D)
Water in the soil zone is used by plants in life functions and leaf transpiration, but it also can evaporate directly to the atmosphere.
Answer:
d
Explanation:
Answer:D) Water in the soil zone is used by plants in life functions and leaf transpiration, but it also can evaporate directly to the atmosphere.
Explanation: Water in the subsurface soil zone is held together by capillary forces. It is also used by plants to carry out their life processes. The soil zone is crisscrossed by roots, openings left by decayed roots, and animal and worm burrows, which allow the precipitation to infiltrate into the soil zone. Water can also evaporate directly into the atmosphere.

-the scientific fields, medical fields, or technical fields
Explanation;
-There are two main systems of measurement in the world: the Metric system and the US standard system.
-The Metric (or Decimal) system is made of units based on powers of 10. To convert units, one needs to move the decimal point.The prefix (beginning part of the word- i.e. kilo or milli) describes the size of the given unit.
Three professional areas in the U.S. that use the metric system are science and scientific research, manufacturing and engineering, and medical and healthcare.
