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.

how might genetic variation arise?
Answer:
Genetic variations can arise from gene mutations or from genetic recombination (a normal process in which genetic material is rearranged as a cell is getting ready to divide). These variations often alter gene activity or protein function, which can introduce different traits in an organism.

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.

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.

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:
New type of diseases, weak defense against disease, decrease in product quality and more production of the product.
Explanation:
New type of diseases, weak defense against disease, decrease in product quality and more production of the product are four trends that threatens genetic progress in animal breeding in the face of climate change challenges. Due to new type of diseases the genetic makeup of organism is unable to defend itself due to weak defense mechanism that leads to decrease in quality of that animal.

Which type of mixture is it, if the solid settles out of the mixture over time?
O suspension
o homogenous
o colloid
solution
Answer:
Suspension
Explanation:
A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing. The particles in a suspension are far larger than those of a solution and thus gravity is able to pull them down out of the dispersion medium (water).
If the solids settle out of the mixture over time, such a type of mixture is called suspension.
A suspension is a heterogeneous mixture in which some of the particles settle out of the mixture upon standing.
What are the different types of mixtures?
there are mainly two types of mixtures that are:
homogeneous mixture
homogeneous mixture
A homogeneous mixture is a mixture throughout the solution in which the composition is uniform throughout the mixture.
A homogeneous mixture is a mixture in which the composition is not uniform throughout the mixture.
Hence, a suspension is a heterogeneous mixture in which some of the particles settle out over time.

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.

If a cubical cell with 2-cm sides doubles the dimensions of its sides, what relative change occurs to the ratio of its surface area to volume ratio?
Answer:
When the length of the side of the cube is doubled, the area increases by a factor of four while the volume increases by a factor of eight.
Explanation:
Surface area of a cube is given by the formula below:
Surface area of a cube = 6a²
Volume of a cube is also given by the formula below:
Volume of a cube = a³
Where a is the length of a side of the cube.
For the first cube, a = 2 cm
Surface area of the first cube = 6 * (2 cm)² = 24 cm²
Volume of the first cube = (2 cm)³ = 8 cm³
When the side length of the cube doubles, a = 4 cm
Surface area of the second cube = 6 * (4 cm)² = 96 cm²
Volume of the first cube = (4 cm)³ = 64 cm³
The ratio of the area and volume of the new cube is given below:
Area = 96 cm² / 24 cm² = 4
Volume = 64 cm³ / 8 cm³ = 8
Therefore, when the length of the side of the cube is doubled, the area increases by a factor of four while the volume increases by a factor of eight.

7. If you have a 100-base pair DNA molecule that contains 45 cytosines, how
many adenines are there?
Answer:
5 adenines
Explanation:
Cytosine pairs with Guanine, and Adenine pairs with Thymine. This means, that if there are 45 cytosines, there must be 45 guanines. So that's 90 base pairs down. That means that there are 10 left between adenine and thymine- so that means there are 5 adenines

https://hub.jhu.edu/magazine/2015/summer/nursing-ethics-and-burnout/
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.
