Permanent magnets are the objects producing the invisible magnetic field. The tools containing the permanent magnets will pick the magnets and iron. Thus, options A and C are correct.
What are permanent magnets?Permanent magnets are the magnetic field-producing materials that pull or repel the ferromagnetic materials towards or away from themselves. The magnetic field is produced from the internal magnetic material.
They are formed when the ferromagnetic objects are heated at high temperatures and have those properties for a very long time. These magnets can attract objects that have magnetic fields around them like iron and other magnets.
Therefore, a permanent magnet will attract magnets and magnetic materials like iron.

n the northern United States where snow and ice create dangerous road conditions in the winter, the Department of Public Transportation often salt roads, which encourages melting. How could salting the roads have and impact on the plant life that live on the edge of the road?
Plant cells will lose water due to osmosis.
Plant cells will gain water due to osmosis.
Plant cells will use the salt to grow taller.
There would be no impact.
Answer:
Plant cells will lose water due to osmosis
Explanation:
Osmosis uses a concentration gradient. Water travels from areas of high concentration to low concentration. The salted road has low water concentration while the plants near the edge have a higher water concentration. The water will leave the plants and go to the salted road. Using common sense, if you sprinkle salt on a snail, it dehydrates and dies. Same thing happens here. The salt sucks the water out.

In an ecosystem, a wide range of organisms coexist. In a pond ecosystem, one can find amoebae, bacteria, green algae, and fish. Which of the
following is the best conclusion one can make regarding the genetic diversity of these organisms?
Green algae will have the greatest genetic diversity because they are photosynthetic and do not depend on other organisms to survive.
Fish will have the greatest genetic diversity because they receive genetic material from a male and female source.
Bacteria will have the greatest genetic diversity because their high reproductive rate ensures that some will survive.
Amoebae will have the greatest genetic diversity because their genetic makeup allows them to survive in many environments.
Answer: Progressives introduced reforms to address the ills of industrial capitalism. Their efforts led to anti-trust law suits (e.g., Northern
Explanation:
Answer:
The correct answer would be "Fish will have the greatest genetic diversity because they receive genetic material from a male and female source".
Genetic diversity is defined as the variation in the total amount of genetic information among the individual of the population.
In sexually reproducing population, genetic diversity is present in high amount as compared to asexually reproducing population.
It is because of two reasons:
The genetic make of an individual is determined by 2 parents (father and mother).
The event of crossing over takes place during formation of gametes.
Together, they lead to the development of new combinations of alleles in an offspring which is different from both the parents.
Thus, fish would have the highest genetic diversity in their population.
Explanation:
Which scenario is likely to result in the most diverse offspring?
Asexual reproduction by budding
Asexual reproduction by binary fission
Sexual reproduction between two individuals in the same population
Sexual reproduction between two individuals from different continents
Answer:
sexual reproduction between two individuals from different continents

how does mangrove planting reduces impact of climate change
Answer:
By slowing down the movement of water and catching sediment, mangroves help reduce the impacts of storm waves and flooding. mangroves also prevent greenhouse gasses which helps climate change.
Explanation:
Answer:
Besides protecting shorelines from extreme weather and providing fish a safe place to breed, mangroves could play a big role in trapping climate-changing carbon emissions, something that has so far been largely overlooked, they said. As mangroves are cleared at a rate three to five times faster than other forests, according to UNEP estimates, those losses are particularly felt in developing countries where most mangroves are located, including Bangladesh, India, Pakistan, Sri Lanka, Kenya, Senegal, West Bengal, Vietnam and Sumatra. Like other plants, mangroves take carbon dioxide from the air as they photosynthesize. They use this carbon dioxide to produce more leaves. As a result, this carbon gets locked in the leaves instead of the air. This is why plant communities like forests and grasslands are called “carbon sinks". As leaves fall from trees, they decompose and the trapped carbon slowly drains back into the atmosphere. Mangrove leaves drop into the water. Lower oxygen levels in that water means that leaves decay more slowly than they would in air. The leaves also serve as a primary food source for a variety of animals like worms, shrimp, fish and crabs. These animals transport that carbon to deeper water. Deeper still if they are eaten by larger animals. When they die, they sink to the bottom where their carbon remains trapped indefinitely.
Given the diagram below, which of the following ordered pairs represents the
vertex, A?
O A. (b cosc, b sinC)
O B. (b cos C, c sinc)
O C. (a cosB, a sinB)
O D. (a cosc, b sinC)
Answer:c
Explanation:because cosin of b is c
(a cosc, b sinC) pairs represents the vertex A in this diagram. Hence option D is correct.
What is Vertex ?In geometry, a vertex (in plural form: vertices or vertexes) is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedral are vertices.
The vertex of an angle is the point where two rays begin or meet, where two line segments join or meet, where two lines intersect (cross), or any appropriate combination of rays, segments, and lines that result in two straight sides meeting at one place.
In a polygon, a vertex is called "convex" if the internal angle of the polygon is less than π radians otherwise, it is called concave.
Hence option D is correct.

Explain why the blood vessels and the heart are not made of the same type of muscle even though they are both involuntary.
Answer:Each muscle in the body is made up of cells called muscle fibers. Muscle fibers are long, thin cells that can do something that other cells cannot do—they are able to get shorter.
Explanation:
IM not sure if this would help but their you go.
Muscle fibers are the cells that make up each muscle in the body. Muscle fibers are long, thin cells with the unique ability to shrink. Most cells cannot do this.
What are Muscle fibers?Cross-striations are the most noticeable histological characteristic of muscle fibres, which are massive multinucleated cells. Many myofibrils with tiny cylinders made of bundle of myofilaments can be found in the cytoplasm.
Myofilaments are made up of both thick filaments primarily made of myosin and thin filaments primarily made of actin. Due to their regular overlap, which is kept in register from across diameter of the muscle fiber, the thick and thin filaments create the cross-striations.
Thus, the cells that make up each muscle in the body are known as muscle fibres. Long, thin cells called muscle fibres have the unusual ability to contract and expand. Most cells are unable to achieve this.

which term names part of the peripheral nerves system A spinal cord B brain C sensors
Answer:
[tex]\boxed {\boxed {\sf C. \ Sensors}}[/tex]
Explanation:
There are two divisions of the nervous system: the central and peripheral.
The central nervous system (CNS) is made up of the brain and spinal cord. This section processes information gathered from the sensory organs.
The peripheral nervous system (PNS) is divided into the autonomic and somatic, with different functions. Regardless of the subdivision, the PNS is made up of all the nerves and sensory receptors. The nerves are connected to the brain and spinal cord, which allows them to pass information from the PNS (where it is gathered ) to the CNS (where it is processed).
So, the spinal cord (choice A) and brain (choice B) are parts of the central nervous system, not peripheral. The correct answer must be C. sensors
