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.

Which best describes the importance of carbohydrates to organisms?
A. Carbohydrates provide an additional source for amino acids.
B.Carbohydrates provide an immediate energy source
C. Carbohydrates provide permanent storage for genetic information.
D.Carbohydrates provide storage for water molecules​

Answers

Answer:

[tex]\boxed {\boxed {\sf B. \ Carbohydrates \ provide \ an \ immediate \ energy \ source}}[/tex]

Explanation:

Carbohydrates are important because they provide the body with energy. It's essential to consume the correct amount of carbohydrates for your body, but make sure they are healthy (examples: whole grain, squash, sweet potatoes, beans)

Carbohydrates are easy for the body to break down. The body will digest these first into simple sugars, like glucose. The glucose is then used in cellular respiration to produce ATP or energy.

Therefore, carbohydrates can quickly provide energy for the body. The best answer choice is B.

Answer:

Carbohydrates provide energy to organisms.

Explanation:

I'm 100% sure because Carbohydrates can also be defined chemically as neutral compounds of carbon, hydrogen and oxygen. Carbohydrates come in simple forms such as sugars and in complex forms such as starches and fiber. The body breaks down most sugars and starches into glucose, a simple sugar that the body can use to feed its cells

Amylase is an enzyme found in saliva that helps break down starches into glucose. Which of
these statements best describes how amylase starts this reaction?
A. Amylase binds to the glucose to start the reaction.
B. Amylase provides extra energy to start the reaction.
C. Amylase decreases the energy needed to start the reaction.
D. Amylase changes the shape of the starch to start the reaction.

Answers

Answer:

Amylase is not the enzyme found in saliva it is ptyalin

Explanation:

the digestion of starch starts in the mouth.

39. What evidence from landforms supports the theory of continental drift and the theory
of plate tectonics?
a. A mountain range in Africa lines up with a mountain range in South Africa
b. All of the continents have mountain ranges along the ocean shoreline
c. Each continent shows evidence that glaciers once covered the land
d. Major rivers in all continents flow to the oceans

Answers

A, because mountains are caused by plates pushing together, and the mountains lining up is a result of that.

The evidence from landforms that supports the theory of continental drift and the theory of plate tectonics is that all of the continents have mountain ranges along the ocean shoreline. Thus, the correct option for this question is B.

What is the theory of continental drift?

The theory of continental drift may be characterized as the movement of the Earth's continents relative to each other, thereby appearing to drift together across the oceanic bed. It is the hypothesis that the Earth's continents have moved over geologic time relative to each other.

The processes of seafloor spreading, rift valley formation, and subduction are some of the major causes of this continental drift. These processes were the main geologic forces behind what Wegener recognized as continental drift.

The movements of the earth's plate form the landforms that are responsible for creating boundaries of the continents that range along the ocean shoreline.

Therefore, the correct option for this question is B.

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.
