<u>Aesthetics </u>is defined as the philosophical study of art and of value judgments about art.
The field of philosophy known as aesthetics is focused on the nature and appreciation of beauty, art, and good taste. The phrase "critical meditation on art, culture, and nature" has also been used to describe it.
The Greek term "Aisthetikos," which means "of sense perception," is where the word "aesthetics" originates. Axiology includes aesthetics along with ethics (the study of values and value judgments).
Assessments of aesthetic worth depend on our capacity for sensory discrimination, but they typically go beyond that. A sensory, emotional, and intellectual component all go into making a judgment of beauty.
Immanuel Kant asserts that all things are lovely (i.e. certain things are beautiful to everyone). However, there is a second, more arbitrary element at play in a viewer's perception of beauty—taste.
Hence, option A is correct.

Answer:
The answer to 1.A is Great Britain.
Ill try to provide more answers in a second.
The French and Indians fought together against Britain. It may be confusing because it was not the French versus the Indians.
People are exposed to natural radiation sources as well as human-made sources on a daily basis. Natural radiation comes from many sources including more than 60 naturally-occurring radioactive materials found in soil, water and air. Radon, a naturally-occurring gas, emanates from rock and soil and is the main source of natural radiation. Every day, people inhale and ingest radionuclides from air, food and water.
People are also exposed to natural radiation from cosmic rays, particularly at high altitude. On average, 80% of the annual dose of background radiation that a person receives is due to naturally occurring terrestrial and cosmic radiation sources. Background radiation levels vary geographically due to geological differences. Exposure in certain areas can be more than 200 times higher than the global average.
Human exposure to radiation also comes from human-made sources ranging from nuclear power generation to medical uses of radiation for diagnosis or treatment. Today, the most common human-made sources of ionizing radiation are medical devices, including X-ray machines.
Exposure to ionizing radiation
Radiation exposure may be internal or external, and can be acquired through various exposure pathways.
Internal exposure to ionizing radiation occurs when a radionuclide is inhaled, ingested or otherwise enters into the bloodstream (for example, by injection or through wounds). Internal exposure stops when the radionuclide is eliminated from the body, either spontaneously (such as through excreta) or as a result of a treatment.
External exposure may occur when airborne radioactive material (such as dust, liquid, or aerosols) is deposited on skin or clothes. This type of radioactive material can often be removed from the body by simply washing.
Exposure to ionizing radiation can also result from irradiation from an external source, such as medical radiation exposure from X-rays. External irradiation stops when the radiation source is shielded or when the person moves outside the radiation field.
People can be exposed to ionizing radiation under different circumstances, at home or in public places (public exposures), at their workplaces (occupational exposures), or in a medical setting (as are patients, caregivers, and volunteers).
Exposure to ionizing radiation can be classified into 3 exposure situations. The first, planned exposure situations, result from the deliberate introduction and operation of radiation sources with specific purposes, as is the case with the medical use of radiation for diagnosis or treatment of patients, or the use of radiation in industry or research. The second type of situation, existing exposures, is where exposure to radiation already exists, and a decision on control must be taken – for example, exposure to radon in homes or workplaces or exposure to natural background radiation from the environment. The last type, emergency exposure situations, result from unexpected events requiring prompt response such as nuclear accidents or malicious acts.
Medical use of radiation accounts for 98 % of the population dose contribution from all artificial sources, and represents 20% of the total population exposure. Annually worldwide, more than 3600 million diagnostic radiology examinations are performed, 37 million nuclear medicine procedures are carried out, and 7.5 million radiotherapy treatments are given.

Answer:
Canada
Explanation:
The Great Lakes are Lake Ontario, Lake Superior, Lake Huron, Lake Michigan and Lake Erie. Lake Michigan is the only one that is entirely in the USA. The rest are either in Canada or are between the two countries.
