Soon after blood is filtered through the nephrons, is released from the body.
Answers
The correct completion of the sentence is: "Soon after blood is filtered through the nephrons, urine is released from the body."
How excretory system works?The excretory system is responsible for the elimination of waste products from the body and the maintenance of proper fluid and electrolyte balance. It consists of several organs and structures, including the kidneys, ureters, bladder, and urethra.
The process begins in the kidneys, which are bean-shaped organs located in the back of the abdomen. Blood enters the kidneys through the renal arteries, and within each kidney, it passes through tiny filtering units called nephrons. Nephrons filter waste products, excess water, and electrolytes from the blood, producing a fluid called filtrate.
As the filtrate passes through the nephrons, essential substances such as glucose, amino acids, and certain ions are reabsorbed back into the bloodstream. This reabsorption occurs in specialized tubules within the nephrons.

List 3 negative impacts does plastic pollution have on the ocean?
Answers
Ingestion
And suffocation
Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.

2. Energy moves around this ecosystem through a food chain. Producers (plants) use sunlight to produce energy through photosynthesis. This energy is then transferred to herbivores (rabbits), which are eaten by carnivores (hawks). Energy is lost at each level of the food chain through respiration and other metabolic processes, so the amount of energy available at each level decreases.
3. If a disease strikes the snake population, the population of hawks and rabbits would be affected. If the snake population declines, there would be fewer predators to prey on the rabbit population. This would cause the rabbit population to increase, which would lead to an increase in the hawk population as they have more food to eat. However, if the disease is severe and the snake population declines too much, there may be a shortage of food for the hawks, causing their population to decline as well.
4. If the rabbit population suddenly doubled, the effect on the grass would be negative. With more rabbits, there would be more grazing pressure on the grass, leading to overgrazing. Overgrazing can lead to a decrease in grass biomass, which can negatively affect other organisms that rely on grass for food and shelter. Additionally, with less grass available, the rabbit population may eventually decline due to a lack of food. This would cause a chain reaction that could lead to the decline of other organisms in the ecosystem.
7. So if a disease stroked the snacks population than the effect on hawks would be that they would feed off a different food source, such as the rabbit. The rabbits population would decrease and soon enough the hawk population would decrease because of the competition towards food. This happens because snakes are secondary consumers and hawks feed off both rabbits and the snakes to balance the populations. If one disappears or decreases than the hawks would aim toward the animal that has a bigger population, the rabbit. Making the rabbit population leading towards less food all around.
8. If the rabbit population doubled than the grass would decrease or would die. This would happen because there is to many consumers and the grass can not keep up with how much it is giving out. This would also lead to a decrease to the rabbit population making the population really low or back to normal, depends on how quickly the grass grows.
Design a device that will knock a block of wood a distance of 5 meters.
This was the challenge in science class. Ben and Sam designed a pendulum to move the wood block. Their first design moved the block about 1.5 meters. They rebuilt their pendulum and changed the mass of the pendulum bob. After the changes, the boys knocked the block of wood 4 meters, 6 meters, and finally 8 meters. The average distance the block moved after the final changes to the pendulum was 6 meters. The boys won the design challenge.
Changing the pendulum design after the first trial was an example of _____________ to solve the problem presented by the teacher.
A) designing the model
B) evaluating the model
C) identifying the problem
D) doing research on the problem
Answers
Changing the pendulum design after the first trial was an example of evaluating the model to solve the problem presented by the teacher. So, the correct option is B.
What is Pendulum?A weight suspended from a fixed position in such a way that it can swing back and forth when pulled by gravity is called a pendulum. The consistent and predictable swinging motion of a pendulum makes it useful for many tasks, such as timekeeping, physics investigation, and engineering design.
In the example above, Ben and Sam analyzed their initial pendulum design after the first try and found that it could only move a wooden block about 1.5 meters. He decided that he needed to modify his design. After making adjustments to the mass of the bob, he rebuilt his pendulum. They were able to knock the wooden block over a distance of 4 m, 6 m and finally 8 m after making these adjustments with an average distance of 6 m.
Consequently, changing the pendulum design after initial testing was an example of evaluating the model and improving it as a result of the evaluation findings.
So, the correct option is B.

BRIANLIST TO WHOEVER ANSWER ALL
Answers
3:I’m sorry I’m not really sure how to answer this one but I’m going to assume that you mean from dark to light. So they liked this time period because the trees were darker due to pollution, this made the darker moths survive from predators while the lighter color moths would be eaten, over time, natural selection would do its course and the whole population of moths would be dark.
4:Well I kind of already answered this but the majority of them were dark because the lighter ones would not be camouflaged therefore making them be easier target for predators and makes the darker moths breed out the lighter ones.
5:Well giraffes cannot live without food so the giraffes with shorter necks would slowly die off making it so only the long necked one would be able to reproduce with babies which would also have long necks, over a long course of time, the shorter necks would be completely gone.
6:Well I wouldn’t say they “grow” longer necks. It’s more like genetic mutation made it so random giraffes would get longer necks then others, since giraffes live in an environment where they have to have long necks only the giraffes with that genetic mutation would survive, and as a said, the longer neck giraffes could only breed with the other Long necked giraffes cause those are the only ones that could survive.
Scientists bred the moths and figured out that the light-colored form of the peppered moth has different genes from the dark form. The black color of the dark form was due to a mutation in the DNA of the light-colored form.

The poles are opposite, so opposite closer together and the distance is closer together, so there is stronger magnetic field
The pair of magnet that have the greatest magnitude would be Pair 1.
Why do they have the greatest magnitude ?Magnets will only attract each other and therefore have a great magnitude if they are facing opposite poles. Pair 3 are therefore out because it has the same pole facing the other.
Magnitude of magnetic force will increase the closer the magnets are to each other. Seeing as Pair 1 has the lowest distance of 0. 3 cm, it means that Pair 1 would have the greatest magnitude.
