How does respiratory failure affect the body?
A. Energy is not given to the body
B. Carbon builds up in the body
C. Oxygen does not make it to the brain
D. Pathogens attack the systems of the body

Answers

From experience with a family member having respiratory failure I'd say it'd be c, but to make sure I'd ask your teacher or a parent.

Oxygen does not make it to the brain is the statement that describes how a respiratory failure affect the body.

Respiratory failure is any situation that leads to a decrease in the amount of oxygen in the blood.

When you breathe, the lungs fill with oxygen, which passes into the blood and, in this way, reaches organs that need oxygen-rich blood to function well, such as the heart and brain.

In this condition, the blood does not receive enough oxygen or has too much carbon dioxide, since it is not removed when you breathe out.

If the brain, muscles or other body organs do not receive enough oxygen, you may experience a sensation of dyspnea, shortness of breath that involves a feeling of discomfort when breathing.

Therefore, we can conclude that oxygen does not make it to the brain is the statement that describes how a respiratory failure affect the body.

How can you use the periodic table to find the number of neutrons in one atom of an element?


The number of neutrons is equal to the number of electrons.

The number of neutrons is equal to the atomic number of the element.

The number of neutrons is equal to the atomic weight of the element.

The number of neutrons is equal to the atomic weight minus the number of protons.

Answers

You can find the number of neutrons in an element by subtracting the number of protons (or the atomic number) from the atomic weight. This is because the protons plus the neutrons are what make up the atomic weight. So, the number of neutrons is equal to the atomic weight minus the number of protons.
Final answer:

To find the number of neutrons in an atom of an element using the periodic table, subtract the atomic number from the atomic weight.

Explanation:

To find the number of neutrons in an atom of an element using the periodic table, you need to look at the element's atomic number and atomic weight. The atomic number represents the number of protons in the nucleus of an atom. The atomic weight represents the average mass of all the isotopes of an element, taking into account the abundance of each isotope.



To find the number of neutrons, you subtract the atomic number from the atomic weight. This is because the atomic weight includes both protons and neutrons, so subtracting the atomic number (which represents the number of protons) gives you the number of neutrons. For example, for helium (atomic number 2, atomic weight 4.0026), there are 2 neutrons (4.0026 - 2 = 2).



Therefore, the correct option is: The number of neutrons is equal to the atomic weight minus the number of protons.

Answers

If the earth was to exceed its weight the of people the population would then decrease because the environment couldnt sustain that many people the carbon would overwhelm oxygen......but its simply just a matter of natural resources (like food) more than anything else.
Final answer:

Exceeding the Earth's carrying capacity can have negative consequences, such as a population crash and collapse of ecosystems.

Explanation:

When the Earth exceeds its carrying capacity, it means that the resources available are being used up faster than they can replenish. This can lead to several negative consequences. For example, if the human population continues to increase, the birth and death rates could decrease, causing a population crash. Additionally, the ecological footprint of humans would increase beyond the Earth's ability to support it, potentially leading to a collapse in the population.

A basketball has a mass of 1 kg and is traveling 12 m/s. How fast would a 6 kg bowling ball have to travel to have the same momentum

Answers

 A bowling ball and a tennis ball can have the same momentum, if the tennis ball with its smaller mass has a ... A 100-kg fullback moving straight downfield ... 175 kg. Velocity of both: v = p total. / m. = (200 kg·m/s) / 175 kg. = 1.14 m/s ... skater with the smaller mass must have the larger velocity: m. 1 v. 1. = m. 2 v. 2 ...

Answer:

The velocity of the bowling should be 2 m/s in order to an have same momentum as that of basket ball.

Explanation:

Momentum is defined as motion possessed by the moving object.it is calculated by multiplying mass of the object with its velocity.

[tex]Momentum(P)=mass(m)\times Velocity(v)[/tex]

Mass of basket ball = m = 1 kg

Velocity of the basket ball,v = 12 m/s

Momentum of the basket ball = p

p = 1 kg × 12 m/s = 12 kg m/s

Mass of bowling ball = m' = 6 kg

Velocity of the bowling ball = v'

Momentum of the bowling ball = Momentum of the basket ball = p

p = m' × v'

12 kg m/s = 6 kg × v'

v ' = [tex]\frac{12kg m/s}{6 kg}= 2 m/s[/tex]

The velocity of the bowling should be 2 m/s in order to an have same momentum as that of basket ball.

How might a chemical spill affect nutrient cycles in soil

Answers

Final answer:

A chemical spill can disrupt nutrient cycles by causing nutrient overload in soils, leading to eutrophication in nearby water bodies, which depletes oxygen and harms aquatic life. The use of artificial fertilizers contributes to this issue, upsetting delicate ecosystem balances and creating long-term ecological consequences.

Explanation:

A chemical spill can significantly affect nutrient cycles in soil, with various negative environmental impacts. Chemicals such as those from fertilizers lead to increased levels of nitrogen and phosphorus, which can cause eutrophication in water bodies. Eutrophication is characterized by excessive algae growth that depletes oxygen, affecting aquatic life and disrupting the balance of ecosystems. Moreover, a chemical spill may also increase soil acidity or alkalinity, altering the soil's ability to hold and cycle nutrients like nitrogen, phosphorus, and sulfur, which are vital for plant growth. In some cases, chemicals may leach nutrients away from soil, diminishing the soil's fertility and impacting plant life.

Human activities including the use of artificial fertilizers exacerbate these effects. Runoff from these fertilizers adds to the nutrient load in water bodies, triggering algal blooms, causing oxygen depletion, and creating dead zones where aquatic life cannot survive. The aftermath of such spills affects not only plants but also the animals that depend on those plants, thereby altering the entire ecosystem.

Nutrient pollution due to overuse of fertilizers in agriculture and residential settings significantly upsets aquatic ecosystems. The runoff contributes to the accumulation of harmful toxins which can affect human health and lead to extensive ecological damage that may take decades to reverse.

Final answer:

A chemical spill can disrupt nutrient cycles in soil by causing excess nutrients like phosphorus to leach away and by promoting eutrophication due to nitrogen-rich compounds. This imbalance can degrade soil health, harm aquatic ecosystems, and contribute to broader environmental issues such as global warming and acid rain.

Explanation:

A chemical spill can greatly affect the nutrient cycles in soil. These cycles are integral to maintaining the balance of elements like nitrogen and phosphorus. A spill can lead to an excess of certain nutrients, which may alter soil chemistry. For example, a chemical spill containing phosphorus can increase its chemical mobility, making it prone to leaching and resulting in a decline in stored nutrients vital for plant growth. On the other hand, nitrogen-rich compounds from artificial fertilizers, if spilled, can cause excessive eutrophication, creating algae overgrowth and depleting oxygen in nearby water bodies, thus jeopardizing aquatic life. Additionally, altered nitrogen cycles due to human activity such as fossil fuels combustion and the use of artificial fertilizers contribute to various ecological disturbances, including global warming and acid rain. Ongoing eutrophication can have serious long-term consequences, such as dead zones in oceans and can disrupt the natural nitrogen fixation process essential for plant and soil health.

When a transition metal reacts with chlorine, what types of bonds are formed between the two elements? A) ionic bonds B) covalent bonds C) transition bonds D) No bonds are formed.

Answers

C I think might be it

Answer : The correct option is, (A) ionic bonds

Explanation:

Ionic bond : It is defined as the bond that is formed by complete transfer of electrons from one atom to another atom.

That means, the atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom.

The ionic bond is usually formed between a metal and a non-metal.

Covalent bond : It is defined as the bond which is formed when sharing of electrons takes place between the atoms.

This is usually formed between two non-metals.

When a transition metal reacts with chlorine then they form ionic bond because transitions metals are metal and chlorine is a non-metal. So, transition metal and chlorine will form an ionic bond.

Hence, the correct option is, (A) ionic bonds
