Sophie was asked to draw a wave with a wave height of 2 meters and a wavelength of 1 meter. Below is the image she drew. What needs to be corrected on the image?
a. The distance from the still water level to the trough needs to be changed to 1 meter.
b. The distance from the still water level to the crest needs to be changed to 1 meter.
c. The distances from the still water level to the trough and the crest need to be changed to 1 meter.
d. The distance between the two crests needs to be changed to 2 meters.
Answers
Answer:
C. The distances from the still water level to the trough and the crest need to be changed to 1 meter.
Explanation:
I took the test also I want to thank the people in the comments for giving me the correct answer
In the image, the distances from the still water level to the trough and the crest needs to be changed to 1 meter. Thus, the correct option is C.
What is wavelength?Wavelength is the spatial period of a periodic wave. It is the distance over which the wave's shape repeats periodically. The wavelength is the distance between two crests and troughs. Wavelength is the distance which is measured by the unit meter. Wave height is the vertical distance between the crest and the trough of a wave.
For example: Still-Water Line is the level of the lake surface if it is perfectly calm and flat. The crest is the highest point on the wave above the still-water line.
The distances from the still water level to the trough and the crest need to be changed to 1 meter in the diagram to correct the wave height and wavelength of the wave.
Therefore, the correct option is C.

Explain the two reasons why DNA changes
Answers
Answer:
1.) Mutation or outside effect
2.) The DNA copies itself
Explanation:
1.) Mutations can occur when a body is exposed to high amounts of radiation or other harmful chemicals, thus changing the DNA.
2.) In order for our bodies to grow, cells must divide and make new cells. Each time a cell makes new cells, the DNA has to copy itself for the new cell. This process is called “replication.”

as cells undergo cellular respiration, what products are produced, and how are they released from the body
Answers
Answer:
The cells reproduce The products of cellular respiration are carbon dioxide and water. Carbon dioxide and there released by being transported from your mitochondria out of your cell, to your red blood cells, and back to your lungs to be exhaled
Explanation:
Hope this helped :D
The products that are produced during cellular respiration are carbon dioxide and water. It uses oxygen as a reactant.
Cellular respiration:The process by which organisms take up oxygen and glucose as food molecules and then convert the energy for various activities leads to the formation of waste products like carbon dioxide and water.
This process breaks down sugar in the presence of oxygen to release energy.

What is the percent by volume of a solution formed by adding 15 L of acetone to 28 L of water?
Answers
Answer:
34.88 %
Explanation:
To solve this question, we are going to assume that the acetone has 100% solution.
We know that 15 L of acetone was added to 28 L of water
We need to determine the percent by volume of a solution as
15 L of acetone/ (15L of acetone +28L of water)
= 15L/43L
=0.3488
= (0.3488×100%)
= 34.88 %
Hence, the percent by volume of a solution formed is 34.88

becuase when the cycle occurs sediments make sedimatary rock and sedimetary rock after heat and pressure it make metamorphic rock not igneous rock.
Statement which is true about rock cycle is that sedimentary rock can revert to metamorphic rock but never to igneous rock.
What are sedimentary rocks?They are the types of rocks which are formed as a result of accumulation of minerals or organic particles at the surface of the earth.Sedimentation is the name given to a collective process which cause the particles to settle.
The study of sedimentary rocks is useful in civil engineering and as important sources of coal, fossil fuels and ores.The color of sedimentary rock is often determined by iron content and sometimes due to the presence of organic matter.
They are classified based on origin in to 4 types which are clastic, biochemical ,chemical and other sedimentary rocks.While based on composition they are classified as siliciclastic,carbonate ,evaporite,organic rich,siliceous ,iron-rich and phosphatic sedimentary rocks.

Answers
Answer:
Explanation:
The seedlings gaining sunlight will help them be able to grow and go through photosynthesis as they are able to gain sunlight which they need
In a tropical forest, the trees often grow very closely together, which reduces the amount of light reaching the forest floor and seeds of many species will not germinate unless they get plenty of light so that they can do photosynthesis and grow.
What are the best conditions for seedling growth?Many factors are required for seedlings to grow, such as proper sunlight, wind, fertile soil, and so on, here seedlings that are present in dense forest that rarely get sunlight never grow, but those that do grow get sunlight, and because they are present in dense forest, there is less transpiration from lower plants.
Hence, in a tropical forest, the trees often grow very closely together, which reduces the amount of light reaching the forest floor and seeds of many species will not germinate unless they get plenty of light so that they can do photosynthesis and grow.
