An earthquake sends out waves in all directions from its source
(epicenter). These waves travel through different materials in Earth.
Properties of a wave change when it moves from one material to
another. What property of a wave changes as it moves from one
material to another?
wave amplitude
wavelength
wave train
wave speed
Answer:
wave train
Explanation:
because a group of waves of equal or similar wavelengths traveling in the same direction.
4. A wave traveling at 200 m/sec has a wavelength of 2 meters. What is the
frequency of this wave?
Given that,
The speed of a wave, v = 200 m/s
Wavelength, [tex]\lambda=2\ m[/tex]
We need to find the frequency of this wave. The relation between wavelength, frequency and the speed is given by :
[tex]v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{200\ m/s}{2\ m}\\\\f=100\ Hz[/tex]
So, the frequency of this wave is 100 Hz.

Describe what might happen in the water cycle if
the amount of solar energy entering the Earth
system decreased.
When the amount of solar energy that enters the system become decreased, what may happen in the water cycle are:
evaporation will reduceclouds won't formprecipitation would dropfreezing will occurThe water cycle can be described as a biogeochemical cycle that depicts how water is being circulated and recycled within, above, and on the earth's surface.
A typical diagram showing a water cycle is attached below.
From the water cycle diagram, we can observe that a vital aspect of the water cycle involves the sun which supplies solar energy that heats up earth.
The solar energy entering earth makes it possible for evaporation of water as vapor which form clouds that leads to rainfall.
The solar energy is also important in melting of ice, thereby converting it to water to goes into oceans for evaporation.
The implication of having an earth system where the amount of solar energy that enters it is reduced is that:
evaporation of water will reduced, clouds will not be able to form, and we won't have enough rainfall, andice would be predominant as low solar energy that is required to melt the ice is reduced.In conclusion, when the amount of solar energy that enters the system become decreased, what may happen in the water cycle are:
evaporation will reduceclouds won't formprecipitation would dropfreezing will occurLearn more here:

How is lactase an example of fitness in humans?
[tex] \\ [/tex]
Evolutionary advantages. Lactase persistence is a text-book example of natural selection in humans: it has been reported to present stronger selection pressure than any other known human gene. However, the specific reasons as to why lactase persistence confers a selective advantage "remain open to speculation".
WHAT THEY DO IN HUMAN BODY?Lactase breaks down the lactose in food so your body can absorb it. People who are lactose intolerant have unpleasant symptoms after eating or drinking milk or milk products. These symptoms include bloating, diarrhea, and gas. Lactose intolerance is not the same thing as having a food allergy to milk.
In pastoralist populations, individuals with the lactase-persistence mutations were more likely to survive, reproduce, and pass on their alleles than people without the mutations, especially in times of famine.

If you assume that the high projection is correct, what is one way the larger
human population can ensure it has enough food?
The one way the larger human population can ensure it has enough food is by finding more efficient ways of growing crops. Therefore, the correct option is option B.
What is population?The term "population" is frequently used to describe the total number of people living in a particular location. To estimate the number of the residents within a certain territory, governments conduct censuses. The phrase has particular use in the domains of ecology and genetics and is also used to refer to plants, animals, and microbes.
An region with a sexual populace is one in which interbreeding between any two individuals therein is both conceivable and more likely than cross-breeding between individuals from other places. The one way the larger human population can ensure it has enough food is by finding more efficient ways of growing crops.
Therefore, the correct option is option B.
