Answer:
False.
Explanation:
All of the things found in the Earth system can be categorized into four (4) main categories and these includes;
I. Land: this subsystem forms a sphere which is generally referred to as litosphere.
II. Water: this subsystem forms a sphere which is generally referred to as hydrosphere. It comprises of landforms such as mountains, valleys, plateaus, ridge, rocks, etc.
III. Air: this subsystem forms a sphere which is generally referred to as atmosphere. This sphere comprises of gases such as oxygen, carbon dioxide, nitrogen, etc.
IV. Living organisms: this subsystem forms a sphere which is generally referred to as biosphere. It comprises of all living things such as humans, animals and plants.
If humans change the function or equilibrium of one of Earth's systems, this will significantly change the function or equilibrium of all of Earth's systems. Consequently, these changes result in environmental phenomenon such as volcanoes, earthquakes, tornadoes, wildfire, etc.
A.
3.1+2.7+4.6+8.7/ 4 because you have 4 numbers
Answer:
Explanation:
J. J. Thomson Electrons are scattered within the atom.
J.J. Thomson carried out experiment on the discharge tube in 1897 which led to the discovery of electrons as a subatomic particle. During this time, the whole atom was thought to be made of only electrons.
John Dalton Atoms are the smallest unit of an element.
John Dalton in 1808 proposed that atoms are the smallest indivisible particles of an element.
Ernest Rutherford Protons are at the center of an atom.
In 1911, Ernest Rutherford performed experiments using gold foil. He discovered that an atom is made up of a massive center made up of positively charged particles called protons.
Niels Bohr Electrons are in orbital levels.
Bohr in 1913 suggested that electrons are in specific spherical orbits around the central nucleus.
<span>The living matter is composed of mainly six elements — carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. These elements together constitute about 90% of the dry weight of the human body. Several other functionally important elements are also found in the cells. These include Ca, K, Na, CI, Mg, Fe, Cu, Co, I, Zn, F, Mo, and Se. Carbon is the most predominant and versatile element of life. It possesses a unique property to form an infinite number of compounds. This is attributed to the ability of carbon to form stable covalent bonds and C—C chains of unlimited length. It is estimated that about 90% of compounds found in living system invariably contain carbon.Life is composed of lifeless chemical molecules. A single cell of the bacterium, Escherichia coli contains about 6,000 different organic compounds. It is believed that man may contain about 100,000 different types of molecules although only a few of them have been characterized.</span>
Sometimes, I think it's just how it reacts to the air but if it was crazy bubbles I'd be skeptical I'm a pretty paranoid person though...
