The main function of the respiratory system is breathing, a process that is also referred to as respiration. This

process allows the body to bring in oxygen and expel (get rid of) carbon dioxide. During respiration, oxygen travels

through the bloodstream and carbon dioxide is carried away.

Breathing air into your body is also necessary for speaking.

Explanation:

Resting metabolic rate (RMR) refers to the total amount of calories that are burned when a person's body is resting, which significantly decreases as we age.

What is the significance of the difference in thickness of the ventricular walls?

Answers

The significance in thickness between the two is due to the different amount of pressure exerted on the walls of the heart. The left ventricle has a thicker wall because the blood must be pumped throughout the entire body (oxygenated blood), unlike the right ventricle, where blood is pumped simply to the lungs to be oxygenated (pulmonary system).
Final answer:

The difference in thickness of the ventricular walls is significant because it is related to the functional requirements of the two ventricles. The left ventricle has a thicker muscle wall compared to the right ventricle, as it needs to generate higher pressure to overcome greater resistance in the systemic circuit. The right ventricle has a thinner muscle wall since it only pumps blood to the lungs with less resistance.

Explanation:

The significance of the difference in thickness of the ventricular walls is due to the functional requirements of the two ventricles. The left ventricle has a significantly thicker muscle wall than the right ventricle because it needs to generate a much greater pressure to overcome the higher resistance in the systemic circuit. On the other hand, the right ventricle has a thinner muscle wall because it only needs to pump blood to the nearby lungs, which have less resistance. This difference in muscle thickness ensures that both ventricles are able to efficiently pump blood to their respective circuits.

Answers

If she deposits $1200 and it earns an interest of $144 over 2 years, then she earns $72 per year. Meaning that after 7 years her account will have a balance of $1704

144/2 = 72

72 * 7 = 504

$1200 + $504 = $1704

Which type of leader sets high expectations but lacks empathy?

Answers

Researchers has shown that there might be four types of leadership styles:
1) Transactor
2) Transformer
3) Relater
4) Overseer
But to answer the query that which type of leader sets high expectations but lacks empathy the answer is, "The Transactors", because transactional leaders,  who have a high process and low people focus tend to be directive in their leadership style. As the name suggests, they are naturally comfortable creating  clear boundaries between themselves and their team members. Therefore, they tend to provide consistent and clear expectations, but also can be demanding and lack empathy, which hinders their ability to build strong relationships and engage with employees.

Achievement-oriented leaders set high expectations but lack empathy.

Achievement-oriented leaders strive for excellence, set challenging goals, and expect high performance from group members. They lack empathy as their focus is on achieving objectives and pushing the group towards success. This leadership style can be effective when dealing with highly skilled and motivated individuals.

A)Republic of Kenya B)Republic of Benin C)Republic of the Sudan D)Central African Republic While many people might scoff at the very concept, light pollution is fast becoming a serious problem. Light pollution most commonly occurs when the beam of a high-wattage fixture is aimed toward the sky. When a spotlight is used to illuminate statues or buildings, for example, some of the light falls on its intended target, while the rest of the light beam is left to scatter into thin air. The result is an effect called urban sky glow, which is essentially a giant shroud of misdirected light that hangs over a city in the night sky. While some may find this phenomenon picturesque when seen from an airplane, it is the reason why only the very brightest stars are visible to citizens of urban environments. As light pollution continues to increase, it is entirely possible that future generations of city dwellers will not be able to see any stars at all.Humans are not the only victims of light pollution; some wildlife species are adversely affected as well. Nocturnal animals such as owls and bats are driven from their own habitats when excessively bright lighting is introduced to these areas. As the growing amount of light pollution causes the habitats of nocturnal creatures to shrink, they will have a more difficult time finding food and breeding successfully. This will inevitably result in a serious population decline unless something is done to keep light pollution in check.Light pollution is a prime example of how most humans habitually consume energy without any consideration of the consequences. It is time that we stop turning a blind eye to the state of the world around us. Working to reduce light pollution is the perfect place to start. Is it truly necessary to have 50 spotlights illuminating trees on a corporate lawn? Is it essential for a restaurant that closes at midnight to have a flashing neon sign operating around the clock? Was the new outlet mall's grand opening only a success because of the 2-megawatt searchlights that hurtled their beams at the stars? Nothing is gained from such blatant waste of light energy.What is the purpose of this essay?A.to make readers aware of the potential harm caused by light pollution and persuade them to take measures to control itB.to inform readers about nocturnal animals facing extinction and persuade readers to take steps to protect those species C.to create interest in environmental science and encourage students to take it up as a career or a life concernD.to convince readers of the need to reduce the consumption of electrical energy and suggest strategies for doing so*Academic Success question* A combination lock requires 4 selections of numbers, each from 1 to 20. how many different combinations are there? suppose that the lock is constructed in such a way that no number maybe used twice. how many different combinations are possible?
