Any cells of the human body, but not cells of the placenta can develop from multipotent stem cells. So, the correct option is A.
What are multipotent stem cells?A specific form of stem cell called multipotent stem cells can only differentiate into a small number of distinct cell types within a given tissue or organ. Multipotent stem cells are more specialized and can only differentiate into specific types of cells, in contrast to pluripotent stem cells, which may differentiate into every form of cell in the body.
Hematopoietic stem cells, which give rise to many blood cell types, and mesenchymal stem cells, which can develop into bone, cartilage, and fat cells, are two examples of multipotent stem cells. Multiple, closely linked cell types of a particular lineage or tissue type can be differentiated into by multipotent stem cells. Human multipotent stem cells have the ability to differentiate into any type of cell in the body, save for placental cells.
Therefore, the correct option is A.

What is the difference between relative and radiometric dating and why is radiometric dating more accurate? SCIENCE
Answer:
Relative age is the age of a rock layer (or the fossils it contains) compared to other layers. It can be determined by looking at the position of rock layers. Absolute age is the numeric age of a layer of rocks or fossils. Absolute age can be determined by using radiometric dating.

Which method best helps to prevent wind erosion?
rotating crops
decreasing riverbank slopes
growing more vegetation
avoiding soil compaction
Answer:
Growing more vegetation
Explanation:
Soil erosion by wind occurs anywhere when vegetation and climatic conditions are conducive. These conditions include presence of very strong winds and when the soil is loose, dry, and is composed of fine granulated particles.
It also occurs when the soil surface is relatively smooth and there is sparse or no vegetative. It can also occur where there are large fields with no windbreak mechanisms in place.
The best way to reduce wind erosion is to keep the wind off the soil surface by covering the soil surface. This involves growing of more vegetation, either cash crops or cover crops which serves to protect the soil and keep the winds higher off the surface.
Also trees can be planted around the farms to serve as wind breaks which breaks or reduces the force of the winds.
Also, soil compaction which is the process of increasing the density of soil by packing the soil particles closer together causing a reduction in the volume of air can help to prevent wind erosion.
From the given options above, the best option would be growing more vegetation.
Practicing crop rotation serves to preserve soil nutrients and prevent diseases.
Decreasing riverbank slopes prevents erosion by water.
Avoiding soil compaction would lead to more erosion by wind.

The fuel for nuclear power plants comes from
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. Although uranium is about 100 times more common than silver, U-235 is relatively rare at just over 0.7% of natural uranium.

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

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.

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.

The football has kinetic energy and the apple has potential energy.
Answer:
The football has kinetic energy and the apple has potential energy.
Explanation:
Potential energy is the energy of an object at rest. Because the apple is hanging from a tree, it is not moving. Therefore, it has potential energy.
Kinetic energy is the energy of an object in motion. Because the football is moving from being in the air to hitting the ground, it has kinetic energy. When it hits the ground, the kinetic energy gets transferred into the ground.

Answer:
if the results are efficient in answering the problems raised in the research and if they manage to come to terms with the hypotheses.
Explanation:
As you may know, scientific research must be done through several steps that allow an experiment to be carried out in order to reach conclusions on a certain topic.
In research on the carbon cycle and global warming, it is necessary for the researcher to raise problems and questions about this topic, as well as to raise hypotheses that must be directly related to the results of the experiment. If the result of the experiment is efficient in answering the research problems and questions, in addition to being able to agree with the presented hypotheses, it means that the research has value within the scientific branch in which it fits, in addition to showing that the experiment was done correctly.
