Which of the following best describes the role of moss in the transition to stage III of the process
vfiekz [6]

Answer:

Hello. You did not put the answer options, but the role of moss in the transition to stage III is the creation of protonemes where the gametes that will act in stage III will be formed.

Explanation:

Stage III consists of the fertilization of the female gamete of the moss with the male gamete of another moss, thus creating a zygote that will give rise to other mosses in the future.

Moss is very important for this phase, because it will be responsible for creating a structure called protonemas. In the protonemas are the gametophytes that will have a structure called gametangium that will allow the formation of gametes.

Armon specializes in framed art. For a specific design of framed art, the width of the frame is 10 inches longer than the width
dlinn [17]

Answer: The answer is: f(x) = 2x^2 + 40x + 200

Explanation:

Given: x is the width of the Artwork

Let W be the Width of the Frame

Let L be the Length of the Frame

Width = x + 10

Length = Width * 2, so by substitution, Length = 2(x + 10)

Area = Width * Length

By substitution:

Area = (x + 10) * 2(x + 10)

f(x) = (x + 10) * (2x + 20)

f(x) = 2x^2 + 20x + 20x + 200

f(x) = 2x^2 + 40x + 200

To test this, if a picture 8" wide is put in this frame, the width would be 8+10 or 18 inches. The length would be twice the width, or 36 inches. The Area is 18 x 36 = 648.

Using the formula:

f(8) = (2 * 8^2) + (40 * 8) + 200

f(8) = (2 * 64) + 320 + 200

f(8) = 128 + 320 + 200

f(8) = 648

What are the two main types of seismic waves that are created during an earthquake (15 points)
Alik [6]

Answer:

- body waves

- surface waves

Explanation:

The earthquakes produce two major types of seismic waves, body waves and surface waves. The body waves are the seismic waves that travel through the layers of the Earth. The surface waves are the waves that only travel on the surface of the Earth and the surface of the water bodies. The earthquakes are a natural phenomenon that occurs most at places where there is more intense geologic activity. Because the crust is cracking and breaking deep inside, lot of adjustments occur, and through the adjustments, lot of energy is released, which is manifested through these two types of waves.
