bot i need your help please come and help me
Of course, I'm here to help! What do you need assistance with?
Remy has learned that rock and soil from avalanches can cause tsunamis by falling into the ocean. Remy wonders if the height of the mountain has anything to do with the eventual size of the tsunami wave. How should Remy test this?(1 point)
Responses
Build different-sized model mountains at the edge of a pool, pour sand down the side of each mountain, and see how large each resulting wave is.
Build a model town at the edge of a pool and see how large waves must be to cause damage to the buildings.
Pour different amounts of sand down the side of a model mountain into a pool and see how large each resulting wave is.
Cause avalanches on several different mountains and see how large each resulting tsunami is.
Stranger danger
The best option for Remy to test the effect of mountain height on tsunami size is to pour different amounts of sand down the side of a model mountain into a pool and observe the resulting wave size. This will allow Remy to control the variable of mountain height while measuring the impact on the generated tsunami waves.
Which is right?
I apologize for any confusion. Both options 1 ("Build different-sized model mountains at the edge of a pool, pour sand down the side of each mountain, and see how large each resulting wave is") and 3 ("Pour different amounts of sand down the side of a model mountain into a pool and see how large each resulting wave is") can help test the relationship between mountain height and tsunami wave size.
Option 1 involves building different-sized mountains to simulate varying heights and observing the resulting wave sizes.
Option 3 involves pouring different amounts of sand down a model mountain to simulate changes in height and measuring the resulting wave sizes.
Either of these options can provide insights into the potential correlation between mountain height and tsunami wave size.
you can only choose 1
If I must choose only one option, I would recommend Option 1: "Build different-sized model mountains at the edge of a pool, pour sand down the side of each mountain, and see how large each resulting wave is."
By building different-sized model mountains and pouring sand down the side of each, Remy can directly observe how the height of the mountain influences the size of the resulting wave in the pool. This method allows for testing the specific variable of mountain height and its impact on tsunami wave size.
Select the group of organelles that is common to both plant cells and animal cells.(1 point)

The correct answer is: ribosomes, cell membrane, mitochondria, cytoplasm.
These organelles are present in both plant cells and animal cells.
At one time, most people believed that the Universe was static, meaning it did not change. When larger and better telescopes were invented in the early 1900s, however, it was discovered that light from objects in space shifted toward longer wavelengths. Scientists concluded that only an expanding Universe could explain this shift. Which of the following statements is supported by this example?(1 point)
Responses
The theory of the expanding Universe cannot change, even if new evidence arises.
The principle of the expanding Universe is a scientific law.
Scientific knowledge can change when new evidence or interpretations arise.
Once a scientific theory has been accepted, it can never change.
