pls mark as brainliest

Explanation:

Each day we breathe about 20,000 times. All of this breathing couldn’t happen without help from the respiratory system, which includes the nose, throat, voice box, windpipe, and lungs. With each breath, you take in air through your nostrils and mouth, and your lungs fill up and empty out. As air is inhaled, the mucous membranes of the nose and mouth warm and humidify the air.

Although we can’t see it, the air we breathe is made up of several gases. Oxygen is the most important for keeping us alive because body cells need it for energy and growth. Without oxygen, the body’s cells would die.

Carbon dioxide is the waste gas that is produced when carbon is combined with oxygen as part of the body’s energy-making processes. The lungs and respiratory system allow oxygen in the air to be taken into the body, while also enabling the body to get rid of carbon dioxide in the air breathed out.

Respiration is the term for the exchange of oxygen from the environment for carbon dioxide from the body’s cells. The process of taking air into the lungs is called inhalation or inspiration, and the process of breathing it out is called exhalation or expiration.

Even if the air you breathe is dirty or polluted, your respiratory system filters out foreign matter and organisms that enter through the nose and mouth. Pollutants are breathed or coughed out, destroyed by digestive juices, or eaten by macrophages, a type of blood cell that patrols the body looking for germs to destroy.

Tiny hairs called cilia (pronounced: SIL-ee-uh) protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose with the breathed air. As air is inhaled, the cilia move back and forth, pushing any foreign matter (like dust) either toward the nostrils, where it is blown out, or toward the pharynx, where it travels through the digestive system and out with the rest of the body’s waste

The mass of an object is 42.8 kg. Calculate the weight on the Earth.​

Answers

Answer:

Weight = 419.44 Newton

Explanation:

Given the following data;

Mass = 42.8 kg

We know that the acceleration due to gravity of all physical objects on Earth is 9.8 m/s².

To find weight, we would use the following formula;

Weight = mass * acceleration due to gravity

Substituting into the formula, we have;

Weight = 42.8 * 9.8

Weight = 419.44 Newton

Explanation:

After the Italian word "novella," which was used for stories in the medieval period, the novel was born in the early 18th century. Its definition has changed over time, and it now refers to a work of prose fiction with a word count of more than 50,000 words. Character development takes precedence over the plot in novels. It is the study of the human psyche in any genre.

Elizabethan prose fiction and French heroic romances, which were long narratives about contemporary characters who behaved nobly, were the novel's forerunners. Due to a growing middle class with more leisure time to read and money to buy books, the novel became popular towards the end of the 1700s. Autobiographies, biographies, journals, diaries, and memoirs became popular due to public interest in human character.

In the story’s opening paragraph and elsewhere, Andy finds comfort and reassurance in the idea the woods are “always the same''; later in the story, she remembers the ocean, “huge and empty, yet always moving. Everything lay hidden…” (par. 45). How does the contrast between woods and ocean suggest the transition she must make from childhood to adulthood?

Answers

Answer:

This is my opinion!

Woods is childhood - ocean is adulthood

As a child, everything is usually the same. Go to school, come home, do homework, play outside, eat dinner, sleep. Repeat, repeat, repeat. Nothing is changing because your parents always have your back, and you have no real responsibilities. As an adult, things are always changing. Something could go wrong at any moment. Forget to pay pills, electricity shuts off, you lose your job, etc.

Read the passage describing the famine that struck Ireland in 1740 to 1741.

In 1740–1741 extremely cold temperatures struck vast areas of pre-industrial Europe, causing harvest failures that led to increased prices for staple food, famine, disease, excess mortality and migration. . . . Ireland was probably more vulnerable than most other European countries. Already in the first half of the eighteenth century, Irish food production was based heavily on potatoes and oats – a pattern of cultivation providing little resilience against the risk of harvest failure after an extremely cold winter. . . . Ireland was ill-prepared to deal with the consequences of harvest failure . . .

I NEED AN ARGUMENTATIVE LETTER WITH EVIDENCE AGAINST SCHOOL DRESS CODE(not uniforms) WILL GIVE BRAINIEST

Answers

Answer:

this will not be as good but feel free to modify (i wrote this in like 10 minutes)

Explanation:

   Plenty of schools around the world have dress codes. Although dress codes will guide students to wear appropriate clothing, dress codes can also be a pain to students in the mornings.

    Many scholars wear inappropriate clothing to schools. Dress codes have been made to prevent this from happening. Although dress codes have their own perks of not having students wear inappropriate clothing, they can make students' mornings more uncomfortable. Waking up early in the mornings can be difficult for some, now imagine that with having to measure out clothing. Students who can't afford to clothe may need to just get dress coded. There are many solutions to avoid this problem in both ways.

      Uniforms have been going around schools. Although they may not satisfy every student's style, they do bring one solution to the struggles of mornings. Some teachers may find this a little bit easier to spot the trouble makers as well. They can easily spot the students not wearing the uniforms and dress code them, rather than trying to measure everything by eye.

      Dress codes can have their own perks of letting the students choose their own clothing with a bit of a guideline. Having to struggle in the morning to find clothes that fit the dress code standards can take up time and result in being late for school. Uniforms are one of many solutions to this problem. Although they do not give students much of a choice, they can solve the issue with both the students and teachers.
