put the stages of cell cycle in order help
Gap 1
cytokinesis
metaphase
Gap 2
telophase
anaphase
s phase
prophase
The stages of cell cycle in order are Gap 1, s phase, Gap 2, prophase , metaphase, anaphase, telophase, cytokinesis.
1. Gap 1 (G1): During this phase, the cell grows in size, synthesizes proteins, and carries out its normal functions. It is the first phase of interphase.
2. Synthesis phase (S phase): In this phase, DNA replication occurs. The cell synthesizes a copy of its DNA, resulting in two identical sets of chromosomes.
3. Gap 2 (G2): During G2 phase, the cell continues to grow, prepare for cell division, and undergoes further protein synthesis. It is the last phase of interphase before entering mitosis.
4. Prophase: The nuclear envelope starts to break down, and the chromatin condenses into visible chromosomes. The spindle fibers start to form, and the centrosomes move to opposite poles of the cell.
5. Metaphase: The chromosomes align at the cell's equator, known as the metaphase plate. The spindle fibers from the opposite poles attach to the centromeres of the chromosomes.
6. Anaphase: The sister chromatids separate and are pulled toward opposite poles of the cell by the shortening spindle fibers. Each separated chromatid is now considered a chromosome.
7. Telophase: The chromosomes reach the opposite poles of the cell, and a new nuclear envelope starts to form around each set of chromosomes. The chromatin begins to decondense.
8. Cytokinesis: The cytoplasm of the cell divides, resulting in two daughter cells. In animal cells, a cleavage furrow forms, pinching the cell in two, while in plant cells, a cell plate forms to separate the two daughter cells.

ully is riding a snowmobile on a flat, snow-covered surface with a constant velocity of 10 meters/second. The total mass of the snowmobile, including Sully, is 280 kilograms. If Sully accelerates to a velocity of 16 meters/second over 10 seconds, what’s the force exerted by the snowmobile to accelerate? Use F = ma, where .
Answer:
168 Newtons.
Explanation:
The computation of the force exerted is shown below:
Since the sully accelerated for a velocity of 16 m/s over 10 seconds
So the excess would be
= 16 - 10
= 6
And, the ratio of change in velocity is
[tex]= \frac{6}{10}[/tex]
= 0.6 m/s
Now as we know that
[tex]f = m\times a\\\\ = 280\ kg \times 0.6[/tex]
= 168 Newtons
Hence, the force exerted is 168 newtons
We simply applied the above formula so that the force could arrive

Determine whether the given procedure results in a binomial distribution (or a distribution that can be treated as binomial). If the procedure is not binomial, identify at least one requirement that is not satisfied. The YSORT method of gender selection, developed by the Genetics & IVF Institute, was designed to increase the likelihood that a baby will be a boy. When 150 couples use the YSORT method and give birth to 150 babies, the genders of the babies are recorded. Does the procedure represent a binomial distribution? A. No, because there are more than two categories for each trial. B. No, because the trials of the procedure are not independent. C. Yes, because the procedure satisfies all the criteria for a binomial distribution. D. No, because the probability of success differs from trial to trial.
Answer:
The correct answer is C)
Explanation:
The number of couples who used YSORT method (x) = 150That is, the number of couples who used YSORT method is limited or defined or definite.The probability of giving birth to a boy, for each couple is 1/2 or 0.5The gender of the baby born in each case mutually exclusive (Independent)
We can conclude that the procedure results in a binomial distribution because the assumptions of the binomial distribution are met.

Why do droughts contribute to desertification?
Answer:
Drought and desertification are firmly related phenomenon. Continuing over months or years, drought can influence enormous zones and may have genuine ecological, social and financial effects.
While drought is a characteristic phenomenon, whose effects can be exacerbated by human exercises that are not adjusted to the neighborhood atmosphere, land debasement is the way toward transforming fruitful land into less or non-gainful land. In extraordinary cases in drylands this is called desertification.
Land debasement and desertification are complex phenomenon driven by un-adjusted human action in mix with land and climatic requirements. Improper land use, for example, monocultures, and unreasonable land the board rehearses, for example, deforestation, unsatisfactory agrarian practices and overexploitation of water assets), can cause land debasement that can be additionally disturbed by drought.

Answer:
Most nuclear reactors are fueled with a compound known as uranium dioxide. This uranium dioxide is put together in a fuel assembly and inserted into the nuclear reactor—where it can stay for several months or up to a few years. While in the reactor the fuel undergoes nuclear fission and releases energy
Explanation:
Answer:
Uranium is the most widely used fuel by nuclear power plants for nuclear fission. Nuclear power plants use a certain type of uranium—U-235—as fuel because its atoms are easily split apart.

The number of chromosomes during meiosis is incredibly important.why is that?
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes, Meiosis also produces genetic variation by way of the process of recombination.
I hope this helps you
Meiosis refers to the process by which a single cell divides twice to produce four haploid daughter cells. These are the gametes, which are sperms in males and eggs in females.
Why the number of chromosomes is important during meiosis?Meiosis is a eukaryotic cell division process. However, the genetic material distributed among the resulting daughter cells is distributed in very different ways by these two processes.
Mitosis results in the formation of two identical daughter cells, each with the same number of chromosomes as the parent cell.
Meiosis, on the other hand, produces four distinct daughter cells, each with half the number of chromosomes as the parent cell.
Because meiosis generates cells that will become gametes (or reproductive cells), this reduction in chromosome number is critical; without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.
Thus, we can conclude that the number of chromosomes during meiosis is incredibly important because It allows gametes to have half the original number of chromosomes of the organism.
