Answer:
Adaptation to their environments!
Explanation:
The mice have different colours of fur because of their surroundings. For example, because the beach mouse lives near- well- the beach, it will have lighter coloured fur to blend in with the sand (and they would need to do that to hide from predators, more than likely). That would be really hard to do if they had dark brown fur hahah~
The same goes for the forest mouse, just instead of sand and changing colour to match something light-coloured, it would change to a dark shade of brown to match the dirt and dark (brown-ish) greens in the forest.
I know this was SUPER late, but I hope I helped in some way ^^
What are Wedges used for? Science. Thank you! <3
Answer:
A wedge is basically a simple machine that consists of two inclined planes, back-to-back. For a wedge, the effort (force) is applied to the vertical (height) of the wedge.
Some examples are knives, axes, chisels, wedges etc.
Their usage is simply for splitting wood, lifting something, cutting etc.
Hope this helps!

Which human activity contributes to the formation of acid rain
Burning fossil fuels such as coal and gasoline
We know that burning fossil fuels, such as coal and gasoline, is a significant human activity that contributes to the formation of acid rain.
When fossil fuels are burned, they release pollutants into the atmosphere, including sulfur dioxide (SO2) and nitrogen oxides (NOx).
These pollutants can react with water, oxygen, and other chemicals in the atmosphere to form sulfuric acid (H2SO4) and nitric acid (HNO3), which are major components of acid rain.
Therefore the correct answer is
Burning fossil fuels such as coal and gasoline
If organisms are being outcompeted in an ecosystem, what could they do?
Answer:
The most obvious result of the removal of the top predators in an ecosystem is a population explosion in the prey species,When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other. When the predators are removed, prey populations explode
Explanation:
Basically they try to balance each other out to the same scale got it!?If organisms are being outcompeted in an ecosystem, the competitive species have to be added to the ecosystem.
The ecosystem has been the area that has been comprised of the biotic and abiotic components that help in survival.
The biotic components in an ecosystem have been consisted of plants, animals, and decomposers that are arranged in the hierarchical order in the ecosystem. The balance between the levels of the ecosystem has been constituent of the proper ecosystem working.
When there has been out-competence in the ecosystem, the number of the species in the ecosystem grows in a large proportion that resulting in an imbalance ecosystem.
The outcompeted species in the ecosystem have been reduced or the competitive species in the ecosystem have been added in order to balance the ecosystem.

Sue is building a bike with a metal frame in a warm, sunny area. Which material would be best for Sue to use for the grips on the handlebars so that her hands do not get too hot?
Answer:
Rubber, or another insulator.

I'm not sure what the options are, but Sue would probably want an insulator so that the heat is trapped, keeping her hands cool.
A mixture contains 21.7 g NaCl,
3.74 g KCI, and 9.76 g Lici.
How many moles of NaCl are in this
mixture?
(Molar Mass)
NaCl: 58.44 g/mol
KCI: 74.55 g/mol
LiCl: 42.3
Answer:
0.371mol
Explanation:
The number of moles of a compound, denoted by n, can be calculated by dividing its mass in grams (g) by its molecular mass in grams per mol (g/mol).
Mathematically; n = mass of compound/ molar mass
According to the question, a mixture contains 21.7 g NaCl,
3.74 g KCI, and 9.76 g LiCl. In order to calculate the number of moles of NaCl in the mixture, we only need to use the mass NaCl compound occupies in the total mixture, which is 21.7g.
The molar mass of NaCl has been given as 58.44g/mol.
Hence, using the formula, we have;
Number of moles (n) = 21.7g / 58.54g/mol
n = 0.3713210
Approximately, n = 0.371mol
Therefore, 0.371mol of NaCl are present in the mixture.

Explanation:
Dew point is the temperature at which water vapor in the air begins to condense into liquid water. The higher the dew point, the more moisture there is in the air. From the starting sounding in the simulation, change the temperature for each point between 800 hPa and 1,000 hPa to 40°C. Then, test how changing the two dew points closest to Earth’s surface (while keeping the temperature constant) affects whether a cloud forms and how big the cloud is if it does form. Describe what you observe, and explain why it occurs.
Answer:
Dew points indicate the amount moisture in the air. The higher the dew points, the higher the moisture content of the air at a given temperature. Dew point temperature is defined as the temperature to which the air would have to cool (at constant pressure and constant water vapor content) in order to reach saturation. A state of saturation exists when the air is holding the maximum amount of water vapor possible at the existing temperature and pressure.
When the dew point temperature and air temperature are equal, the air is said to be saturated. Dew point temperature is NEVER GREATER than the air temperature. Therefore, if the air cools, moisture must be removed from the air and this is accomplished through condensation. This process results in the formation of tiny water droplets that can lead to the development of fog, frost, clouds, or even precipitation.
Relative Humidity can be inferred from dew point values. When air temperature and dew point temperatures are very close, the air has a high relative humidity. The opposite is true when there is a large difference between air and dew point temperatures, which indicates air with lower relaitve humidity. Locations with high relative humidities indicate that the air is nearly saturated with moisture; clouds and precipitation are therefore quite possible. Weather conditions at locations with high dew point temperatures (65 or greater) are likely to be uncomfortably humid.

Locations with high relative humidities indicate that the air is nearly saturated with moisture; clouds and precipitation are therefore quite possible. Weather conditions at locations with high dew point temperatures (65 or greater) are likely to be uncomfortably humid.
As per the given scenario, the temperature for each point between 800 hPa and 1,000 hPa is changed to 40°C. This means that the temperature of the air at all those altitudes is the same.
What are dew points?Dew point is the temperature at which the air becomes saturated with water vapor, leading to the formation of dew, fog, or clouds when the temperature drops further.
Now, the two dew points closest to Earth’s surface are changed while keeping the temperature constant. Dew point is the temperature at which water vapor begins to condense into liquid water. Therefore, changing the dew point changes the amount of moisture in the air.
When the dew point is close to the air temperature, the relative humidity is high, and the air is almost saturated with water vapor. In such a case, if the dew point is raised even slightly, the air becomes saturated, and the water vapor condenses into liquid water.
On the other hand, if the dew point is lowered, the relative humidity decreases, and the air becomes drier. In such a case, the chances of cloud formation are reduced.
Therefore, if the dew point is raised close to the air temperature, a cloud forms. The size of the cloud will depend on the amount of moisture present in the air. The higher the dew point, the more moisture there is in the air, and the bigger the cloud will be.

3. A recent flood in the area has caused many short-term changes to
the ecosystem. Which is a long-term change?
A. Standing water in the streets and sewers
B. Temporary displacement of organisms
C. Permanent change in the landscape
D. Poor water quality in rivers and streams
Answer:
c
Explanation:
While standing water in the streets and sewers (option A) and poor water quality in rivers and streams (option D) may persist for some time after the flood, they are generally considered short-term changes as they can eventually be remedied through clean-up efforts and restoration programs.
Temporary displacement of organisms (option B) can also be considered a short-term change, as organisms will eventually return to their original habitats once conditions improve.
However, a permanent change in the landscape (option C) such as altered river channels, new water bodies, or changes in topography, can have lasting effects on the ecosystem and its inhabitants. These changes may alter habitat suitability, nutrient cycling, and water availability, which can impact the ecosystem for years or even decades to come.
Answer: C
Explanation:
The landscape could be flooded. Houses and buildings may be restricted.
