Answer:
Taking into account the concepts presented in chemistry with respect to elements and compounds, it is possible to affirm that the compounds are formed by two or more elements.
Explanation:
Two or more chemical elements have the ability to bind -by forming bonds- to obtain a compound. This occurs randomly in nature.
The bonds between the elements that form a compound must be stable enough to ensure the stability of the molecule. A chemical compound can only be separated into the elements that form it by chemical processes.
The bonds types that form compounds can be:
- <em>Ionic bond.</em>
- <em>Covalent bond.</em>
- <em>Coordinated covalent bond.</em>
- <em>Metallic bond.</em>
It is necessary to mention that chemical elements are called atoms, and the bonds between them are molecules. The physical and chemical properties of a compound will be different from the properties of the elements that form it.

Hello YOU!
Explanation:
Phrenology was a science of character divination, faculty psychology, theory of brain and what the 19th-century phrenologists called "the only true science of mind."Phrenology came from the theories of the idiosyncratic Viennese physician Franz Joseph Gall (1758-1828).
Gall believed that the bumps and uneven geography of the human skull were caused by pressure exerted from the brainunderneath. He divided the brain into sections that corresponded to certain behaviors and traits that he called fundamental faculties. This is referred to as localization of function.
Phrenology is considered pseudoscience today, but it was actually a vast improvement over that era's prevailing views of personality. ... But phrenology may be undergoing a redemption of sorts. Not the skull part—that's still considered bunk.
Phrenology was particularly popular in the U.S. because it fit so well with the idea of the American dream–the notion that we can accomplish our goals despite a humble heritage. Spurzheim believed that the brain was like a muscle that could be exercised.
Answer:
The life process may be defined as the different process that are important for the sustenance of life. The most important life process are nutrition, respiration, excretion and transportation.
If the mouse is placed in the closed sealed container then the weight will remain before and after the experiment of 1 or 2 week. This is because the life process metabolic reactions will use and conserve all the atoms involved in the life process. These atoms can exist in the liquid, solid and gas forms but present inside the container.
