When atom decays, two or more forms of the same element are obtained. These forms are called isotopes and they have the same number of protons but a different number of neutrons in relation to the parent atom. So they differ in the relative atomic mass, which is the number of core particles, while the chemical properties remain the same as the parent atom. This process takes place with radioactive decays where radioactive isotopes are obtained, and the time required for decay is half life, and this is the time that is needed for half atom parent to decay and form the daughter elements.

The new deal did little to change the relationship between the American people and their government true or false?

Elenna [48]

Answer:

True

Explanation:

So, your question is straight foward, but what I do know is that The New Deal included new constraints and safeguards on the banking industry and efforts to re-inflate the economy after prices had fallen sharply. New Deal programs included both laws passed by Congress as well as presidential executive orders during the first term of the presidency of Franklin D. Roosevelt.

Mnenie [13.5K]

Answer:

Susan B. Anthony was never married, and devoted her life to the cause of women's equality. She once said she wished “to live another century and see the fruition of all the work for women.” When she died on March 13, 1906 at the age of 86 from heart failure and pneumonia, women still did not have the right to vote. (February 15, 1820 March 13, 1906) was an American social reformer and. The women's movement was loosely structured at that time, with few state organizations and no national organization other The funding Train had arranged for the newspaper, however, was less than Anthony had expected. Anthony founded the National Women's Suffrage Association in 1869 with fellow women's suffrage activist Elizabeth Cady Stanton. She drafted the first version of the 19th Amendment in 1878. Just before she retired in 1900, Anthony was asked if women would be given the right to vote in her lifetime. Hope That Helps!

How did Theodore Roosevelt enact "control of corporations" while he was president?

Marta_Voda [28]

Answer: The Square Deal was Theodore Roosevelt's domestic program, which reflected his three major goals: conservation of natural resources, control of corporations, and consumer protection. These three demands are often referred to as the "three Cs" of Roosevelt's Square Deal.

Explanation: One of Roosevelt's acts as president was to deliver a 20,000-word address to Congress asking it to curb the power of large corporations (called "trusts"). He also spoke in support of organized labor to further chagrin big business, but to their delight, he endorsed the gold standard, protective tariffs and lower taxes.

I will surely help you..

Explanation:

#When we breathe, we inhale oxygen and exhale carbon dioxide. The so-called exchange of gases is necessary for metabolic activities and can be considered a chemical process.
Every organism, from an individual bacterial cell to a mighty blue whale, undergoes respiration. This respiration is carried out by a system of organs known as the Respiratory System and the respiration in humans is carried out by the human respiratory system.
Let us explore respiratory system notes to have a detailed understanding of the human respiratory system, its parts, functions and the process of respiration in humans.
Respiratory System Definition
“Human Respiratory System is the organ system that involves inhaling of oxygen and exhaling of carbon dioxide to meet the energy requirements.”
What is the Respiratory System?
The human respiratory system consists of a group of organs and tissues that help us to breathe. Lungs are the primary organs of the respiratory system which help in the exchange of gases. The other main parts of this system include a series of airways for air passages, blood vessels and the muscles that facilitate breathing.

#Features of the Human Respiratory System
The respiratory system in humans has the following important features.
The energy is generated by the breakdown of glucose molecules in all living cells of the human body.
Oxygen is inhaled and is transported to various parts and are used in the process of burning food particles (breaking down of glucose molecules) at the cellular level in a series of chemical reactions.
The obtained glucose molecules are used for discharging energy in the form of ATP- adenosine triphosphate molecules by the human body to fulfil essential life processes.

#Respiratory System Parts and Functions

Let us have a detailed look at the different parts of the respiratory system and their functions.

Nose
The nose possesses a couple of exterior nostrils, which are divided by a framework of cartilaginous structure termed as the septum. This is the structure that evenly separates the right nostril from the left nostril. Tiny hair follicles that cover the interior lining of nostrils acts as the body’s first line of defence against foreign pathogens. Furthermore, they provide additional humidity for inhaled air.
Larynx
Two cartilaginous chords lay the framework for the larynx. They are situated at the point of joining the pharynx and trachea. It is also termed as Adam’s apple or the voice box. It is the portion which rises and falls during swallowing of food particles. It generates sound as air passes through the hollow in the middle.
Pharynx
The nasal chambers open up into a wide hollow space termed as the pharynx. It is a common path for both air and food. It functions by preventing the entry of food particles into the windpipe. The epiglottis is an elastic cartilage, which serves as a switch between the larynx and the oesophagus by allowing the passage of air into the airway to the lungs, and food in the gastrointestinal tract.

Talking while we eat or swallow results in incessant coughing. The reason behind this reaction is the epiglottis. It is forced to open for the air to exit outwards and the food to enter into the windpipe, triggering a cough.
Trachea
The trachea or the windpipe rises below the larynx and moves down to the neck. The walls of trachea comprise C-shaped cartilaginous rings which give hardness to the trachea and maintain it by completely expanding. The trachea extends further down into the breastbone and splits into two bronchi, one for each lung.
Bronchi
The trachea splits into two tubes termed as bronchi, which enter each lung individually. The bronchi divide into secondary, tertiary, and to bronchioles, which is again further divided into small air-sacs called the alveoli. The alveoli are minute sacs of air with thin walls and single-celled manner. It enables the exchange of oxygen and carbon dioxide molecules into or away from the bloodstream.
Lungs
Lungs are the chief centres of the respiration in humans and other vertebrates. They are located in the thoracic cavity of the chest near the backbone and on either side of the heart. They are the pair of large, spongy organs, mainly involved in the exchange of gases between the blood and the air. Compared to the left lung, the right lung is quite bigger and heavier.
