Run the dishwasher only when it has a full load of dishes, helps in reducing water usage of Kieran. Option B is correct.

Reduce the energy costs by using less energy to heat and pump water. Delay or avoid the expansion of expensive water and wastewater treatment plants in your municipality to save money on taxes.

Reduce the frequency and severity of water shortages. Install rooftop canals so that rainfall may be utilized for home uses or recharged groundwater.

When washing garments, use the full capacity of your washing machine. To reduce evaporation, water the plants in the evening. Instead of taking a shower, use buckets to save water.

Answer:

Electromagnetic waves can travel through empty space

Explanation:

Electromagnetic waves can travel through empty space.

Invisible energy forms called electromagnetic waves are able to move throughout the cosmos. Nonetheless, some of the effects of this energy are visible. The electromagnetic spectrum includes the light that our eyes can see.

The colors we see in a rainbow, from reds and oranges to blues and purples, are all part of the visible portion of the electromagnetic spectrum. In reality, each of these hues represents a distinct light wavelength.

We are unable to observe the waves that create the sound we hear. In order for sound waves to go from one location to another, they need a medium to pass through. Because air is composed of molecules, sound can move across it.

Therefore, Electromagnetic waves can travel through empty space.

Explanation:

Answer: All plasma membrane surfaces are hydrophilic. In comparison, because of the fatty acid tails, the interior of the membrane between its two surfaces is a hydrophobic or nonpolar region. The main fabric of the membrane is composed of two layers of phospholipid molecules. The hydrophilic or "water-loving" areas of these molecules are in contact with the aqueous fluid both inside and outside the cell. Hydrophobic, or water-hating molecules, tend to be non-polar.

Explanation:

The phospholipid is positioned in the plasma membrane the hydrophilic regions of phospholipids are exposed to the cytosol and extracellular environment, while the hydrophobic regions are in the interior of the bilayer. The correct option is d.

Hydrophilic surfaces characterize all plasma membrane surfaces. In contrast, the inside of the membrane between its two sides is a hydrophobic or nonpolar region due to the fatty acid tails. The membrane's main fabric is made up of two layers of phospholipid molecules.

These molecules' hydrophilic or "water-loving" regions are in contact with the aqueous fluid both inside and outside the cell. Hydrophobic, or water-hating, compounds are typically non-polar.

The correct answer to this open question is the following.

Mass media and communications technology can be used to preserve indigenous languages in the Americas in different ways.

According to the graphics attached, we can see that in the Americas, 17% of the languages are lost and 16% are endangered.

This data is critical and concerns not only scholars or historians, but it has to worry all the citizens because part of our history can be erased if indigenous languages disappear.

Mass media can be used to help solve this issue because modern technology has no frontiers. If governments invest in proper technological infrastructure to take modern communications systems to the tribes or far away places where many tribes inhabit, this could be a direct way to rescue those endangered languages. This possibility shows that there are options available. The use of the internet is a great resource, proving that no matter the distance, every member of a society or indigenous tribe can be connected and could take classes on the internet, or listening to news broadcasting systems in their former language, as well as reading publications in their languages.

Answer:

Jefferson of the Democratic-Republican Party defeated incumbent President John Adams of the Federalist Party. The election was a political realignment that ushered in a generation of Democratic-Republican leadership.

Explanation:

Thomas Jefferson was the third President of the United States, from 1801 until 1809. He was also Vice-President of the United States from 1797 to 1801 and the main author of the Declaration of Independence.

Jefferson belonged to the Democratic-Republican Party, opposed to the Federalist Party (which supported the British policies in Europe, more conservative). Therefore, Jefferson had a republican ideological alignment that was concordant with that of the French Revolution, which was rightly opposed to the conservatism defended by the federalists.

Therefore, the events that took place in France during the late 1790s greatly influenced the political stance of Jefferson and his supporters facing the presidential elections of the year 1800.
