Given the diagram below, which of the following ordered pairs represents the
vertex, A?
O A. (b cosc, b sinC)
O B. (b cos C, c sinc)
O C. (a cosB, a sinB)
O D. (a cosc, b sinC)
Answers
Answer:c
Explanation:because cosin of b is c
(a cosc, b sinC) pairs represents the vertex A in this diagram. Hence option D is correct.
What is Vertex ?In geometry, a vertex (in plural form: vertices or vertexes) is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedral are vertices.
The vertex of an angle is the point where two rays begin or meet, where two line segments join or meet, where two lines intersect (cross), or any appropriate combination of rays, segments, and lines that result in two straight sides meeting at one place.
In a polygon, a vertex is called "convex" if the internal angle of the polygon is less than π radians otherwise, it is called concave.
Hence option D is correct.

Answers
Answer:
Photosynthesis products serve as a chemical energy suppliers for reactants and cellular respiration.
Since photosynthesis creates oxygen and oxygen needed for cellular respiration in the production of carbon dioxide and energy, carbon dioxide is used to generate plant energy and oxygen.
Explanation:
Photosynthesis products produce chemical energy by reacting to cellular respiration. Photosynthesis products interact to extract ATP from cells in cellular breathing reactants.
Photosynthesis products inhibit the reactants in the presence of light in cellular breathing.

In what aspect the enzyme is different from other catalysts ? help please
Answers
Answer:
Enzymes and catalysts both affect the rate of a reaction. In fact, all known enzymes are catalysts, but not all catalysts are enzymes. The difference between catalysts and enzymes is that enzymes are largely organic in nature and are bio-catalysts, while non-enzymatic catalysts can be inorganic compounds.

Which choice best describes the parts of the water cycle? The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth. The ocean's tidal energy causes water to cycle on the earth. The water from the oceans evaporate and form precipitation. The precipitation then condenses back on the surface of the earth. The earth's magnetic energy causes water to evaporate. The water condenses into water vapor once it becomes precipitation. The condensation then falls back to the surface of the earth. The sun's thermal energy causes water vapor to condense. This condensation then forms precipitation. This precipitation returns to the atmosphere for the cycle to continue.
Answers
Answer:
The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth.
Explanation:
The water cycle is an illustration of how water continuously moves or circulates between the atmosphere and the various parts of the earth.
Evaporation of water from the surface of the earth by the thermal energy from the sun causes water to leave the surface of the earth into the atmosphere. When the atmospheric water vapor (humidity) at the upper strata of the atmosphere becomes high, the vapor condenses to form clouds which later forms precipitation that falls back to the surface of the earth.
The ocean's tidal energy does not cause water to cycle on earth.

Answers
Answer:
similar results in multiple tests of the claim
Explanation:
e2020 told me so
Similar results in multiple tests of the claim are a factor found in a scientific claim.
What is a scientific claim?The statements made regarding an issue in the field of science are referred to as a scientific claim. Scientific claims are different from any other form of a claim as they are made after a lot of research and are backed by data.
Science is basically a systemically done study of the world around us. People practising in the field of science are called scientists. They collect data, analyze it and based on this analysis they come to conclusions.
Thus a scientific claim is a statement made after coming to the conclusion after analyzing the data.
Even though, a scientific claim is made after thorough research, not every scientific claim is as reliable. The experimentation and analysis can be subject to various errors which can cause a faulty scientific claim.
Therefore, the factor present in a scientific claim would be similar results in multiple tests of the claim.

NEED HELP ASAP: List two ways in which the atmosphere would be impacted in the absence of the biosphere. Use complete sentences.
Answers
Answer:
If there would be no biosphere on earth the atmosphere would be quite different. There would be no oxygen to support because oxygen is liberated by plants in photosynthesis so no plants means no oxygen. The earth would be a planet without life just like Venus and Mars. Therefore, no organism would be surviving in the world.
There would be no negligible green house effect and global warming since it is all created due to activities of men.The earth's atmosphere would be much cleaner and with lesser amount of CO2 and O2 but no organism would be there to use them.
Hope it help!
There would be more carbon dioxide, which would eventually burn away the ozone layer, as well as no oxygen, and all animal and plant life would perish.
What is biosphere?The biosphere is basically comprised up of the areas of the Earth where life can be found.
The biosphere encompasses all the things from the deepest tree root systems to the dark environment of ocean trenches, including lush rainforests, and high mountaintops. Earth is described by scientists in terms of spheres.
Because it is all of life, the biosphere is as important as life itself. Earth would be a lifeless planet like Mars or Venus without the biosphere. Human insecurity grows as natural resources are depleted.
The biosphere is the zone that contains all living things. The biosphere requires the lithosphere, hydrosphere, and atmosphere to exist. There would be no life on Earth if these three spheres did not exist.
Thus, this way, the atmosphere would be impacted in the absence of the biosphere.
