Here is ur answer

Lack of plankton growth

Answer:

B

Explanation:

I just did the unit review on edge

Answer:

Explanation:

initaial velocity=o m/s

final velocity =?

acceleration=4m/s

time=5 sec

acceleration=final velocity-initial velocity/time taken

4=final velocity-0/5

4*5=final velocity- 0

20+=final velocity

20m/s=final velocity

Answer:

106 cm³

Explanation:

A prism is a 3-dimensional shape with two identical shapes known as bases facing each other. A triangular prism is a prism with two identical triangles facing each other as well as having three rectangles.

Area of rectangle 1 = 7 cm * 5 cm = 35 cm²

Area of rectangle 2 = 7 cm * 5 cm = 35 cm²

Area of rectangle 3 = 7 cm * 3 cm = 21 cm²

Area of each triangle = 1/2 * 5 cm * 3 cm = 7.5 cm²

Surface area of prism = 2 * area of triangle + Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3

Surface area of prism = 2(7.5) + 35 + 35 + 21 = 106 cm³

Answer:

Spanish is spoken throughout Central and South America because these are the regions colonized by Spain after Columbus discovered the New World.

The colonization of Americans contributes to why Spanish is much spoken in Central and South America.

As far back as the 1500s, the Spanish and Portuguese have started exploring the world for search of gold, silver, domination etc.

The Spanish has attempted to colonized the North America but was not a successful quest.

The successful colonization of majority of Latin countries in South America leads to ability of the resident to speak Spanish because the language was introduced to them during colonization.

Answer: who had the greatest need?

Explanation:

Answer:

C) Who has the greatest need

Explanation:

Answer:

b). only regions with extremely high altitudes can have the required climate there because of the high temperatures near the equator.

Explanation:

As per the question, the key reason for the alpine biome being scarce down the equator is the 'higher temperatures in the equatorial and nearby regions.' Alpine biomes are majorly found in the regions having higher altitudes(around 10,000 feet) like mountain regions which provide adequate climatic conditions for their survival while the equatorial regions fail to provide it. Thus, such plants are not found commonly across warm areas because such high temperatures are directly opposite to the conditions required for such biome to survive. Hence, option b is the correct answer.

Answer:

open pit-mining

Explanation:

Open-pit mining, also known as mega-mining, open-cast, or open-cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow.

Answer:

there color brown

Explanation:

the color brown is used to denote most contour lines on a map

Answer:

The color brown is used to denote most contour lines on a map, which are relief features and elevations. Topographic maps use green to denote vegetation such as woods, while blue is used to denote water features like lakes, swamps, rivers, and drainage.

Answer:

I would say the 2nd one. Its more exciting and more likely to be read by the readers.

Explanation:

I might be wrong!! Just what I think :)) have a good day!

Answer: d

Explanation: Early telescopes focused light using pieces of curved, clear glass, called lenses. However, most telescopes today use curved mirrors to gather light from the night sky. The shape of the mirror or lens in a telescope concentrates light. That light is what we see when we look into a telescope.

Explanation:

Answer:

Troposphere, Mesosphere, Stratosphere, Thermosphere, Exosphere.

Explanation:

The atmosphere is divided into five layers. It is thickest near the surface and thins out with height until it eventually merges with space.

The troposphere is the first layer above the surface and contains half of the Earth's atmosphere. Weather occurs in this layer.

Many jet aircrafts fly in the stratosphere because it is very stable. Also, the ozone layer absorbs harmful rays from the Sun.

Meteors or rock fragments burn up in the mesosphere.

The thermosphere is a layer with auroras. It is also where the space shuttle orbits.

The atmosphere merges into space in the extremely thin exosphere. This is the upper limit of our atmosphere.

Answer:

An air mass forms when air stays over an area for a while or moves slowly over a area  - true.

Air masses that form over over land are moist - false.

Air masses that form over tropical regions are warm. - true.

Polar air masses that form over warm regions.-  false.

A warm air mass that forms over the Caribbean Sea is a maritime tropical air mass- True.

Air masses that form over dry land are tropical air masses. - False.

Explanation:

We can say that air masses are large volumes of air that have homogeneous and relatively stable temperature, pressure and humidity and that move slowly over a region, influencing weather conditions for a certain period of time. They can form in large volumes of water or land. When the air mass forms on land it is quite dry, however the air mass that forms in water is quite moist.

Tropical air masses are those that form in intermediate latitude regions, close to the equator and therefore are warmer, have high temperatures and low pressure, unlike polar air masses that form in high latitude regions , near the poles. A hot air mass that we can mention is the one that forms in the Caribbean Sea, which is a tropical maritime air mass.

Answer:

foo[6];

Explanation:

there is no explanation

Answer:

500 m³

Explanation:

Given that :

Base, b is a square measured at 10 m

Height, h = 15 m

The volume of a pyramid = 1/3 * b² * h

Plugging the values :

Volume = 1/3 * 10² * 15

Volume = 10² * 5

Volume = 100 * 5

Volume = 500 m³

Answer:

How do free trade agreement affect the global economy?

Free trade agreements don't just reduce and eliminate tariffs, they also help address behind-the-border barriers that would otherwise impede the flow of goods and services; encourage investment; and improve the rules affecting such issues as intellectual property, e-commerce and government procurement.

Explanation:

sorry I just copy this

Correct me if I'm wrong

Answer:

Canada exports a large proportion of its mineral production, the mining industry is sensitive to world price fluctuations.

Nobody has ever lived in 80% of Canada. The country’s land remains mostly unexplored. Canada is bigger than the entirety of Europe.  

There are areas where there isn’t a road for hundreds of kilometers. The First People live mostly around the edges, and the Europeans mostly live within a hundred kilometers of the American border.

So, the resources are untapped because nobody is there to tap them

Explanation:

From 1990 to 2009, Canada's natural resource wealth, on average, grew by 6% per year. Our abundance of natural resources—such as timber, potash, uranium, oil and gas, and gold—as well as increasing demand for natural resource commodities worldwide are among the factors that have contributed to this growth.
