Describe the Earth's crust, mantle and core. Include the thickness, composition, temperature and pressure of each layer in your description.
PLS DO Asap
Explanation: The Earth’s outermost layer, its crust, is rocky and rigid. There are two kinds of crust: continental crust, and ocean crust. Continental crust is thicker, and predominantly felsic in composition, meaning that it contains minerals that are richer in silica. The composition is important because it makes continental crust less dense than ocean crust.
Ocean crust is thinner, and predominantly mafic in composition. Mafic rocks contain minerals with less silica, but more iron and magnesium. Mafic rocks (and therefore ocean crust) are denser than the felsic rocks of continental crust.
The crust floats on the mantle. Continental crust floats higher in the mantle than ocean crust because of the lower density of continental crust. An important consequence of the difference in density is that if tectonic plates happen to bring ocean crust and continental crust into collision, the plate with ocean crust will be forced down into the mantle beneath the plate with continental crust.
Mantle
The mantle is almost entirely solid rock, but it is in constant motion, flowing very slowly. It is ultramafic in composition, meaning it has even more iron and magnesium than mafic rocks, and even less silica. Although the mantle has a similar chemical composition throughout, it has layers with different mineral compositions and different physical properties. It can have different mineral compositions and still be the same in chemical composition because the increasing pressure deeper in the mantle causes mineral structures to be reconfigured.
Rocks higher in the mantle are typically composed of peridotite, a rock dominated by the minerals olivine and pyroxene. The Tablelands rock in Figure 3.2 is a type of peridotite. Lower in the mantle, extreme pressures transform minerals and create rocks like eclogite (Figure 3.5), which contains garnets.

The diagram below shows a sarcomere. If a disorder makes it impossible for
ATP to bind to the myosin head, which symptom would a person suffering
from this disorder most likely display?
Myosin
Actin

nie
A. Weak muscle contraction
B. Difficulty breathing
O O O
C. Uncontrolled muscle contraction
D. Increased heart rate
C. Uncontrolled muscle contraction
If a disorder makes it impossible for ATP to bind to the myosin head, a person would be suffering from symptoms like uncontrolled muscle contraction. Thus, the correct option is C.
What is Myosin?Myosin may be defined as a superfamily of motor proteins that convert chemical energy in the form of ATP to mechanical energy. This will generate force and movement.
During the controlled muscle contractions, ATP must bind to the myosin head to disrupt the cross-bridge which is formed with actin and enables the myosin to rebind to actin spontaneously.
Therefore, the correct option for this question is C.

Answer:
In every department of each health facility, nurses grapple with ethical challenges every day. Experts say that nurses face unique challenges because of long-term patient and family relationships. sometimes unsustainable decisions are nursing caregivers. "Nurses are often unable to choose patient care," says Rushton. Rushton. "Rushton says that the nation is at a crossroads in health," says a nursing and pediatrics professor. Some of these are serious situations. Johns Hopkins has initiatives and programs to stimulate ethics discussions, especially among nurses. Many hospitals have codes of conduct or guidelines which guarantee quality and safety, although fewer are ethical. Ethics can stay behind when nurses are busy, says Rushton. Initiatives are being developed in Kimmel Cancer Center to support nurses in tackling long-term cancer moral challenges. For students of the graduate school, the Johns Hopkins School of Nursing is specialized in ethics and theory. Students learn about their values and how to sympathize with those on the other side by engaging in debates and debates.
US Nurses Association that prepares to publish its report 50 health care leaders met for the First National Care Ethics Summit in Baltimore in August 2014. The resulting plan on the ethics of the 21st century lays down what can progressively be done to ensure that nurses are prepared. The nursing students of today are going to be nurses of tomorrow, says Rushton. He believes that the common voice of nursing workers can be mobilised in discussions with policymakers, hospital administrators, medical organizations and insurance companies in order to create a culture that values and promotes the practice of ethics.

Scientists have used the eight levels of classification for more than 200 years. When might the system be updated?
Answer: If new species, studies come to the table and the classification is not compatible with them
Explanation: Like a new animal was discovered but even using the eight levels of classification scientists couldn't figure what the animal was
The system might be updated when new species discovered don't match
any level of classification.
The levels of classification help to differentiate plants and animals through
the presence of specific features or behavior.
When new living things are found and the required feature for classification
doesn't match any of the available levels then the scientists can decide to
include a new one to accommodate the new species discovered and for
subsequent study.

Ryan and Jessica meet at a party and start talking. They hit it off immediately and find a quiet corner to make out in. Over the course of the evening, Jessica consumes much more alcohol than Ryan does and is slurring her speech and having a hard time standing up. Ryan recognizes that Jessica is drunk but likes that she is being playful and flirtatious. Ryan suggests that they go out to his car to "take a break" from the party and talk. Jessica agrees but has to be physically steadied as they leave the party. They get out to Ryan's car and start making out. Pick a character and explain how you would best handle this situation.
Please be appropriate because this is gonna effect my actual grade
Answer:
if i were ryan, i would take jessica back to her house. i would take care of her if there wasn't anyone else there, or if her family was there i would make sure that she was safe and being taken care of. once I knew she was safe and she was comfortable, I would leave and go back to my house. if she wanted me to stay, i would do that, but i wouldn't do anything physical (anything beyond kissing) while she was under the influence because if she's that drunk she wouldn't be able to give consent

Select the correct the correct answer. The arrows indecate the direction of flow. Which place experiences monsoos?
Answer:
India experiences the monsoon season
Explanation:
From the picture, it can be seen that India experiences the monsoon season.
This is evident in that the southwestern summer monsoon is brought into a low-pressure area primarily as a result of great heat moving over the Thar Desert in places like Rajasthan and other nearby areas during summer.
This is illustrated in the picture as wind direction moves inwards at this period, making the moisture-rich wind blowing from the Indian Ocean moves to the low-pressure region, hitting the great Himalayas, and thereby leads to rainfall.

Which must happen first in order for the body to use the fuel energy stored in food?
A.
The food must first be digested and combined with carbon dioxide.
B.
The food must first be released as ATP within the cells.
C.
The food must first be digested and combined with oxygen.
D.
The food must first be created in the cells by cellular respiration.
Answer:
b
Explanation:
ATP gives us energy, so I think that's the answer
However, food must first be digested, broken down into its component parts, absorbed by the cells, and stored before cells may release energy, hence option c is correct.
What is the process of food digestion?
Oxygen combines with the fundamental components of food, such as carbs, lipids, and proteins, during aerobic respiration, to make ATP molecules, which are used as reactants.
The initial process of breaking down glucose to release energy for cellular metabolism is called glycolysis.
An energy-consuming phase and an energy-releasing phase make up glycolysis. The glucose is absorbed by the stomach and small intestines before being released into circulation.
Therefore, upon entering the bloodstream, glucose can either be utilized right away for energy or stored for later use, hence option c is correct.
