The last section of the article shows the severity of ocean acidification and it’s devastating effects on marine and human life by:
A.stating several facts
B.making a comparison
C.providing a detailed image
D.asking rhetorical
The last section of the article likely demonstrates the severity of ocean acidification by potentially employing methods like stating facts, making comparisons, providing images, or posing rhetorical questions. Ocean acidification, mainly caused by atmospheric CO2, has grave implications for marine ecosystems and human life.
Explanation:The student's question is referring to how the severity of ocean acidification is portrayed in the last section of an article. Highlighting the article's strategy for conveying the impact on marine and human life could involve different methods. For instance, presenting several facts would offer hard data illustrating the effects, while a comparison might show the contrast between the present state of oceans to past conditions. Providing a detailed image could visually depict the damage, and utilizing rhetorical questions might engage the reader to think critically about the issue.
Ocean acidification is a significant global issue caused primarily by atmospheric CO2 dissolving in ocean water. This results in a lower pH value in oceans, making them more acidic, and adversely affects many marine species by reducing the availability of calcium carbonate, crucial for building shells and skeletons. If CO2 concentrations continue to rise, corals and other marine life could face severe declines, impacting marine ecosystems and the humans who rely on them.
Which factor would scientists most likely evaluate to determine the health of a marine ecosystem?
Frequency of predation
Levels of pollution
Particulates in the air
Reproductive success of consumers
Answer: levels of pollution

B. from neurotransmitters to neuroendocrine cells for translation
C. from hormones to glands to endocrine target cells
D. from endocrine target cells to hormones to neurons
I thinks the answer is c,from hormones to glands to endocrine target cells
The brain communicates with the endocrine system via neuroendocrine cells to neurons. Neuroendocrine cells receive messages from nerve cells and release hormones into the bloodstream.
Explanation:Messages sent by the brain to the endocrine system pass from neuroendocrine cells to neurons for translation (Option A). In the body, neuroendocrine cells are special cells that receive neuronal input (neurotransmitters released by nerve cells) and, in response to this input, release message molecules (hormones) into the bloodstream. This allows for communication from the nervous system to the endocrine system.

Will the carbon atom's journey ever end?
Yes, it will eventually be used up
No, it will continue cycling through the Carbon cycle forever
Yes, it will eventually run out of energy
The journey of a carbon atom is a continuous cycle. It doesn't end or run out of energy but continues to be recycled in the Carbon cycle.
Explanation:The journey of a carbon atom through the carbon cycle is considered to be an ongoing process that continues indefinitely, not something that ends. This is because the carbon cycle is a closed system with carbon continuously being recycled from the atmosphere, into living organisms, and back again. It is important to note that a carbon atom doesn't 'run out of energy', instead it is transferred and transformed through various chemical reactions during its journey through the cycle.

The carbon cycle consists of a number of biotic (living) and abiotic (nonliving) factors that act as carbon reservoirs, or locations where more carbon is stored than released. Carbon travels constantly from reservoir to reservoir, sometimes stopping for a very long time and sometimes stopping for only a short time. Which of the following are abiotic carbon reservoirs?
(choose all that apply)
oceans
animals
atmosphere
fossil fuels
sun
decomposers
Answer:
Fossil fuels
Atmosphere
decomposers
Explanation:
The following are abiotic carbon reservoirs: oceans, atmosphere, fossil fuels, and the sun. As abiotic substances don't reproduce like animals and plants, while biotic organisms can,
What is the carbon cycle?The carbon cycle is the process by which carbon is exchanged among the Earth's atmosphere, oceans, land, and living organisms. Carbon is constantly moving between these reservoirs through various processes, such as photosynthesis, respiration, and decomposition. Abiotic (non-living) reservoirs are locations where carbon is stored, but there is no biological process associated with them. The carbon cycle maintains the rate of photosynthesis too.

What is the difference between a conductor and an insulator?
Question 2 options:
A conductor can get heat transfer through convection and conduction and an insulator can only get heat transfer from radiation
A conductor lets heat pass through it easily, and an insulator does not allow heat to pass through it easily
A conductor can only get heat transfer through conduction, and an insulator can only get heat transfer through radiation
A conductor is unaffected by heat, and an insulator is extremely affected by heat
A conductor allows heat and electrical charge to pass through easily, facilitating heat transfer through conduction and convection; an insulator does not allow heat or charge to move through it easily, limiting heat transfer mainly to radiation.
Explanation:The difference between a conductor and an insulator lies in their ability to transfer heat and electrical charge. A conductor, such as metals like copper, aluminum, and silver, allows heat and electrical charge to pass through it easily because of the movement of electrons within the material. Conductors can transfer heat through physical contact (conduction) as well as by the movement of the material itself (convection). On the other hand, an insulator like wood, plastic, or rubber does not allow heat or electrical charge to move through it easily, primarily restricting heat transfer to radiation, which does not require direct contact.
Describe how gene therapy can be a social issue and give rise to moral, ethical, and legal debates. Justify your response in two or more complete sentences.
Answer:This type of gene therapy cannot be passed to a person's children. Gene therapy could be targeted to egg and sperm cells (germ cells), however, which would allow the inserted gene to be passed to future generations. This approach is known as germline gene therapy. The idea of germline gene therapy is controversial.
Explanation: I hoped this helped, im only in 5th grade
Final answer:
Gene therapy poses ethical, social, and legal issues regarding access, equity, regulation, and the scope of genetic modification, with debates surrounding the correction of traits, enhancement, and manipulation of future generations. High-profile cases have highlighted the risks and necessitated strict regulation.
Explanation:
Gene therapy can be a social issue as it brings forth a wide array of moral, ethical, and legal debates. Issues arise over who should have access to gene therapy and whether it could create new forms of social inequality due to its cost. Furthermore, concerns exist on who will regulate and police the use of gene therapies, especially to prevent exploitation and misuse.
Another significant debate contrasts the ethical considerations of somatic cell gene therapy, which affects only the individual, versus germ-line gene therapy, which has hereditary implications, potentially affecting future generations. Questions such as which genetic traits are worthy of being corrected, if gene therapy should be used for cosmetic or enhancement purposes, or whether we should genetically manipulate the unborn for desirable traits, invoke deep ethical dilemmas about the limits of therapy.
The case of Jesse Gelsinger, among others, illustrates the need for stringent regulation and ethical consideration. It led to increased scrutiny and temporary halts in clinical trials, forcing a balance between scientific progress and human welfare. There is considerable federal and local regulation of the development of gene therapies, underscoring the potential risks and the need for rigorous evaluation of new therapies.
Carbon cycles in nature can be balanced, so the concentration of CO2 in the atmosphere stays relatively constant. However, if the total amount of trees and other plants increased worldwide, CO2 levels in the atmosphere would decrease. Explain why.
Answer:
During Northern Hemisphere spring and summer months, plants absorb a substantial amount of carbon dioxide through photosynthesis, thus removing it from the atmosphere and change the color to blue (low carbon dioxide concentrations).

Which of these is an example of redevelopment?
A. Drawing an urban growth boundary around an area
O
B. Converting rural pastureland into a new shopping center
O
C. Converting an old shopping mall into a community college
D. Putting a parking garage on an unused lot inside a city
"The correct answer is C. Converting an old shopping mall into a community college. Option C is an example of redevelopment.
Redevelopment typically refers to the process of taking an existing property or area and transforming it for a new use, often to revitalize or improve the area. Here's the reasoning for each option:
A. Drawing an urban growth boundary around an area is an example of urban planning and land-use regulation, but it does not involve the transformation of existing structures or land use within the boundary. Therefore, it is not an example of redevelopment.
B. Converting rural pastureland into a new shopping center is an example of development, as it involves creating a new structure or use on previously undeveloped land. This is not redevelopment because the land was not previously developed for another purpose.
C. Converting an old shopping mall into a community college is a clear example of redevelopment. It involves taking an existing structure that was used for one purpose (retail) and repurposing it for a completely different use (education). This fits the definition of redevelopment as it revitalizes the property and gives it a new function.
D. Putting a parking garage on an unused lot inside a city is also an example of development rather than redevelopment. While it does involve constructing a new structure, the lot was previously unused, so there is no transformation from a previous use to a new use, which is a key aspect of redevelopment.
Therefore, option C is the correct choice as it best exemplifies the concept of redevelopment."

Answer:
The answer to the question is
D. It initially caused a large drop in chicken pox cases in the united states and the rate continues to decrease.
Explanation:
The varicella vaccine introduced in 1995 led to a significant reduction in chickenpox cases in the United States, demonstrating the effectiveness of vaccines in controlling and managing infectious diseases.
Explanation:Based on the information and the graph depicting the number of varicella (chicken pox) cases between 1972 to 2011, it can be concluded that the introduction of the varicella vaccine in 1995 had a significant impact on the reduction of chicken pox cases in the United States. Following the vaccine's introduction, there was a notable decline in virus spread. As seen with many other vaccines such as smallpox, measles, mumps, and polio, the targeted immunization measures tend to significantly reduce the prevalence of the associated diseases.
Once a person is vaccinated, the body develops immunity against the virus, significantly reducing the chances of infection. It's also important to note that, similar to diseases like polio, the successful reduction of chickenpox cases through vaccination showcases the importance and effectiveness of vaccines in controlling and managing infectious diseases on a broad scale.
