Answer:
53°.
Explanation:
Rhese method can be used to identigy the orbital projectioons of the organism. The median sagittal plane are specified at the particular angles to obtained the projections.
IR in parieto-orbital projection and median sagittal plane by the rhese method forms the angle of 53° in the projections. These projections are important for the medical diagnosis of individual.
Thus, the correct answer is option (C).
Answer:
Scientist 1
Explanation:
<em>The conclusion of scientists 1 is valid.</em>
Human activities such as burning of fossil fuels, agriculture, deforestation, etc. leads to the emission of carbon in the form of carbon dioxide into the atmosphere. <em>An increase in the population of a city will only lead to an increase in these activities and hence, an increase in the amount of carbon emitted into the atmosphere.</em>
Also, volcanic activities leads to the production of volcanic gases which is a mixture of carbon dioxide, oxides of sulfur, nitrogen, etc.
<u>However, an active volcano that is several miles away from the city might not be a major source of carbon in the air above a large city. The carbon dioxide produced from such volcanic activity thins out before reaching the city.</u>

Answer:
Explanation:
Weathering can best be defined as the physical, chemical and biological disintegration of rocks to form sediments and soils.
It is an important natural process that has sculpted landscapes and produced useful Agricultural soils over decades.
From the definition, one can extract three main types of weathering.
- Physical weathering is also known as mechanical weathering. It is the breaking down of rocks to form soils by physical means. The freezing and thawing of ice, thermal expansion of rocks, salt crystal growth, pressure release e.t.c causes chunks and bits of rocks to fall off and form soils.
- Chemical weathering is the decomposition of rocks to form sediments and soils. It involves oxidation, carbonation, hydration and even hydrolysis of rocks to form soils.
- Biological weathering utilizes the life activities of plants and animals to drive weathering. Burrowing animals breaks of chunks of rocks and power them into essential soil matter. Chemicals secreted during life process of plants are important to weathering.
