Explanation:
Biomagnification is the process by which toxins and pollutants become increasingly concentrated in the bodies of animals as they move up the food chain. This means that organisms at the top of the food chain, such as humans, can end up with dangerously high levels of these pollutants in their bodies if they consume contaminated prey.
When does this phenomenon is concerning ?This phenomenon is particularly concerning when it comes to certain toxins, such as mercury and persistent organic pollutants (POPs) like PCBs and DDT. These toxins can have serious health consequences, including neurological damage, developmental delays, and cancer.
One example of biomagnification in action is with mercury contamination in fish. Mercury is released into the environment through various human activities, including burning coal and waste incineration. When this mercury enters waterways, it can be transformed into methylmercury, a highly toxic form that accumulates in the tissues of fish and other aquatic organisms.
As larger fish consume smaller fish, the concentration of methylmercury in their bodies increases, leading to dangerously high levels in the bodies of top predators like sharks and swordfish. When humans consume these contaminated fish, they can also accumulate dangerous levels of methylmercury in their bodies.
Similarly, POPs like PCBs and DDT can enter the food chain through contaminated soil and water. As these toxins move up the food chain, they become increasingly concentrated in the bodies of top predators like birds of prey and mammals like seals and polar bears.
These toxins can have serious health consequences for these animals, including reproductive problems and weakened immune systems. When humans consume these contaminated animals, they can also accumulate dangerous levels of these toxins in their bodies.
Biomagnification is a serious issue that highlights the importance of careful monitoring of environmental pollutants and the need for sustainable practices to prevent contamination in the first place.

2. Which of the following describes a negative feedback system?
running cattle increase panic within a herd
microphone speaker feedback
feedback that magnifies output
feedback that regulates and stabilizes
Answer:
Feedback that regulates and stabilizes
Explanation:
Negative feedback systems are ones that try to always maintain homeostasis, or a certain state.
For example, the regulation of body temperature in humans is a negative feedback loop. This is because the body maintains a constant temperature at homeostasis, and will adjust if it is too hot or cold.
Feedback that regulates and stabilizes is a negative feedback system, because it involves regulation/stabilization, similar to the regulation of body temperature.
So, the correct answer is Feedback that regulates and stabilizes
Answer:
feedback that regulates and stabilizes

What are the different types of granulocytes? Select all that apply.
basophils
T-cells
eosinophils
monocytes
neutrophils
There are four types of granulocyte;
Explanation:
basophils, eosinophils, neutrophils and mast cells.
The different types of granulocytes are: basophils (option A), eosinophils (option C), and neutrophils (option E). Granulocytes are a type of white blood cell that are characterized by the presence of granules in their cytoplasm.
What are granulocytes?The three types of granulocytes are basophils, eosinophils, and neutrophils such as basophils are the least common type of granulocyte. They are characterized by their large, dark-staining granules and play a role in allergic reactions and inflammation. Basophils release histamine, which causes blood vessels to dilate and become more permeable. Eosinophils are the second-least common type of granulocyte, and neutrophils are the most common type of granulocyte. They are characterized by their small, pale-staining granules.
Hence, the different types of granulocytes are: basophils (option A), eosinophils (option C), and neutrophils (option E).

Describe and explain the abiotic and biotic factors that may affect the numbers or distribution of organisms in their habitats.
Answer:
The biodiversity and distribution of organisms within an ecosystem is due to both abiotic (non-living) and biotic (living) factors. Abiotic factors are non-living variables that can influence where organisms can live. Examples of abiotic factors include: light intensity.

HELPPPPP Some factories that burn coal produce smoke with harmful chemicals, such as sulfur. Scrubbers are devices that are attached to the smokestacks to reduce the amount of sulfur put into the atmosphere. To evaluate the effectiveness of these devices, what data would need to be collected?
A. The percentage of sulfur contained, on average, in a certain amount of coal
B. The amount of coal a factory burns each year, and how much sulfur it emits
C. The increase, over time, in the use of scrubbers by factories that burn coal
D. The amount of sulfur emitted by a smokestack before and after the scrubber is attached
Answer:
D. The amount of sulfur emitted by a smokestack before and after the scrubber is attached
To evaluate the effectiveness of these devices, the data would need to be collected is the amount of sulfur emitted by a smokestack before and after the scrubber is attached. The correct option is D.
What are scrubbers?Scrubbers are devices for reducing air pollution that employ liquid to filter out gases or particles from an industrial exhaust or flue gas stream. To effectively remove particles and polluting gases from the gas flow, this atomized liquid (usually water) entrains them.
Wet scrubbers are tools that use direct contact with a liquid spray to capture suspended particles. As the many small droplets in the spray collide with and entrain the particulates, a scrubber effectively washes the contaminants out of the contaminated air stream.
Therefore, the correct option is D.The amount of sulfur emitted by a smokestack before and after the scrubber is attached.

Please put in order for a food chain.
Answer: C) The benthic invertebrates would decrease in population size because they are eaten by the sea ducks and the phytoplankton would increase in population size.
Explanation:
The benthic invertebrates are eaten by sea ducks. Sea ducks are eaten by bald eagles. If the bald eagle was removed, there would be more sea ducks because they will have no more predators. Since there are more sea ducks, they will need to eat more food, like benthic invertebrates. The benthic invertebrates would have a lower population because the sea ducks eat more of them.
Why not the other answers:
A) The bivalves would not increase in population size. Without the bald eagle preying on sea ducks, there would be more sea ducks, who need to eat more food, such as eating more bivalves.
The phytoplankton would not decrease. With sea ducks eating more food, more benthic invertebrates are eaten. There would be less benthic invertebrates to eat phytoplankton.
B) Tundra swans were never eaten by bald eagles. There is no arrow connecting them.
D) Wading birds were never eaten by ospreys. There is no arrow connecting them.
