What are the nature protection strategies of the United States?The 42,826 protected areas in the United States covered 1,235,486 km2 in 2022, or 13% of the country's land area. The country system includes 424 areas which covering more than 85 million acres in every state, the District of Columbia, and American Samoa.
The smallest park is Gateway Arch National Park in Missouri, which is 91 acres. This is also one-tenth of the world's protected land area. National parks protect a total of approximately 52.2 million acres, with a median of only 208 thousand acres.
Therefore, other nations should also follow the same strategies and do afforestation.

Considering ethical questions is part of a marine scientist’s job. Part of being ethical is doing your homework and exploring all sides of an issue. Choose a current ethical issue in marine science, such as the use of genetically modified organisms (GMOs), conditions in fish farms, or another topic your instructor approves. Find two perspectives supporting one side of the ethical issue and two supporting the other. Be sure to use reliable sources, such as university web sites or newspaper/magazine articles. Create an outline with at least five points for each side. Then write a brief paragraph explaining what you believe an ethical choice around this issue is. Remember, ethical problems are difficult because both sides have valid points. Be sure to consider and discuss at least one point you think is valid from the side that you disagree with in your conclusion as you explain why your choice is the ethical one. Also, include a list of sources that you used. Two is the minimum for each point of view.

One current ethical issue in marine science is the use of genetically modified organisms (GMOs) in aquaculture.
What are genetically modified organisms?Genetically modified organisms (GMOs) are living organisms whose genetic material has been artificially altered in a laboratory using genetic engineering techniques.Here are two perspectives supporting each side of the issue:
Perspective 1: According to a report by the World Health Organization (WHO), GMOs have the potential to reduce the environmental impact of aquaculture by decreasing the need for wild fish as feed, reducing the use of antibiotics, and decreasing the risk of disease outbreaks.
Perspective 2: Opponents of GMOs in aquaculture argue that they pose a significant risk to wild fish populations and the environment. According to the Ocean Conservancy, GMO fish can escape from fish farms and breed with wild fish, potentially altering the genetic makeup of natural populations and harming biodiversity.
Therefore, use of GMO's is profitable as well as hazardous for the environment.

Answer:
Size of milky way galaxy is very large than our solar system.
Explanation:
The size of the solar system is much smaller than the size of the milky way galaxy because our solar system is a part of milky way galaxy. The radius of our solar system is 4.545 billion km while on the other hand, the radius of the milky way galaxy is 52,850 light years which is very very large than the radius of our solar system. Milky way galaxy has 100–400 billion planets while in our solar system has only eight planets.

1: For example, rhinovirus has over 100 different serotypes. Now, the good news is that you can't get ill from the same virus serotype right after getting better, due to the fact that you'll have developed antibodies which help to protect your immune system for a little while.
2:Most children in the United States are now vaccinated against measles virus; before vaccination was widespread, most were naturally exposed to this virus and suffered from an acute, unpleasant, and potentially dangerous viral illness. Whether through vaccination or infection, children exposed to the virus acquire long-term protection from measles. The same is true of many other acute infectious diseases: this state of protection is a consequence of immunological memory.
The basis of immunological memory has been hard to explore experimentally. Although the phenomenon was first recorded by the ancient Greeks and has been exploited routinely in vaccination programs for over 200 years, it is just now becoming clear that memory reflects a persistent population of specialized memory cells that is independent of the continued persistence of the original antigen that induced them. This mechanism of maintaining memory is consistent with the finding that only individuals who were themselves previously exposed to a given infectious agent are immune, and that memory is not dependent on repeated exposure to infection as a result of contacts with other infected individuals. This was established by observations made on remote island populations, where a virus such as measles can cause an epidemic, infecting all people living on the island at that time, after which the virus disappears for many years. On reintroduction from outside the island, the virus does not affect the original population but causes disease in those people born since the first epidemic. This means that immunological memory need not be maintained by repeated exposure to infectious virus

CELLULAR RESPIRATION
What happens to the energy after cellular respiration? What happens to the carbon dioxide and water?
Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP. Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid.

A child pulls a toy across the floor. What is the equal and opposite force for the force of the child pulling forward on the toy as described by Newton's third law? Choose 1 answer: Choose 1 answer: (Choice A) A Ground's normal force pushes up on the child's feet. (Choice B) B Ground's friction pushing on the toy (Choice C) C Child's feet's friction pushing on the ground in the opposite direction (Choice D) D Toy pulls on the child in the opposite direction
Answer:
D. Toy pulls on the child in the opposite direction
Explanation:
Newton third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever an object 1 exerts a force (action force) on another object 2, object 2 exerts a force (reaction force) of equal magnitude but opposite direction on object 1.
According to this question, a child pulls a toy across the floor. Based on Newton third law described above, the toy will pull the child with an opposite force that is equal in magnitude. Hence, the equal and opposite force is: Toy pulls on the child in the opposite direction.
