Explanation:
When you have had the chickenpox virus once, the Antigen . Presenting . Cells (A.P.C) have the ability to produce antibodies that latch onto the chickenpox pathogen. This then attracts other white blood cells to perform phagocytosis.
A chicken pox vaccination will usually protect a person from chickenpox for the rest of their lives due to the white blood cells being able to tell when the pathogen of chickenpox has entered the body. This vaccine is essentially a dead form of chickenpox.

Ocean Acidification Evidence
Ocean Warming Evidence
:: expansion of ocean volume
:: difficult for some species to make shells
:: larger concentration carbonic acid
:: melting of glaciers and ice caps
growing difficulty in absorbing carbon dioxide
:: organisms more prone to illness
Answers
Answer:Ocean Acidification Evidence: Difficult for some species to make shells , larger concentration, organisms prone to illness . Ocean warming evidence: Melting of glaciers, expansion of ocean volume, growing difficulty in absorbing
Explanation:
Ocean Acidification Evidence includes difficult for some species to make shells , larger concentration, organisms prone to illness. Ocean warming evidence encompasses melting of glaciers, expansion of ocean volume, growing difficulty in absorbing.
What is ocean acidification?The massive amount of carbon dioxide absorbed by the ocean dissolves as carbonic acid in seawater.
This is known as ocean acidification, and it is literally causing a sea change that is threatening the basic chemical balance of ocean and coastal waters from pole to pole.
As greenhouse gases trap more solar energy, the oceans absorb more heat, resulting in higher sea surface temperatures and rising sea level.
Ocean acidification is the decrease in pH of ocean water caused by CO2 dissolution in water.
Ocean warming, on the other hand, is the long-term gradual increase in the average temperature of the Earth's atmosphere. Ocean acidification and global warming are both negative consequences of human activity.
Acidification of the Oceans Evidence: It is difficult for some species to make shells, there is a higher concentration, and organisms are prone to illness.
Melting glaciers, increased ocean volume, and increasing difficulty absorbing are all signs of ocean warming.
Thus, this is the match for the given scenario.

Answer:
Not sure
Explanation:
Please put in order for a food chain.
Answers
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.

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
Answers
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.

Answers
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).
