Help please, tysm if you do :) _______ acts on groups of paired muscles. When one muscle contracts, the opposite muscle cannot contract because no stimulus is sent. Sliding-filament mechanism Synergistic contraction Reciprocal innervation Antagonistic contraction
Answer:
Hey there!
I think your answer would be "Antagonistic Contraction." That basically means when one muscle contracts, the other one relaxes. That's why when one muscle contracts the other one can't. It is "forced" to relax.
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.

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.

Both football and apple have potential energy.
The football has potential energy and the apple has kinetic energy.
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.

Proteins in the cell membrane have many functions. Which type of protein would be able to transport materials in or out of the cell, and signal other cells? A. Integral proteins B. Glycoproteins C. Pore proteins D. Endoplasmic proteins
Answer:Integral proteins
Explanation: according to a video lesson in Founder Education
Integral proteins present in the cell membrane help in the transportation of materials and the signaling of other cells.
What are integral proteins and their functions?Integral proteins are the proteins attached permanently to the plasma membrane and are embedded in the whole layer of the membrane.They are also known as intrinsic proteins.Functions of intrinsic proteins:Transportation: Hydrophilic compounds may be able to get through the cell membrane due to intrinsic proteins.Signal transduction: A binding site may be present in certain membrane proteins. These binding sites have distinctive structures that closely resemble those of chemical messengers. A receptor membrane protein that is placed inside the cell wall will link with a hormone when it comes into contact with the cell wall. Depending on the type of hormone or other chemicals, the hormone can alter the receptor protein and induce a certain reaction to occur inside the cell.Learn more about membrane proteins here:

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

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.

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.
