Answer: b. The temperature at the Earth's center may almost equal the temperature of the Sun's surface.

Explanation:

The Earth's core is very very hot due to various factors such as heat from radioactive materials decaying and the heat the earth had when it was formed. It is estimated that the temperature here is around 5,200° C which means that it can melt even Tungsten.

This is almost equal to the surface temperature of the sun which is around 5,500° C.

Answer: b. Different plant types can add or remove nutrients within a soil, thereby changing the type of soil that is formed.

Explanation:

Some plants require more a of particular nutrient than others and so will draw more of these nutrients from the soil whilst giving away some of the ones that they do not want. This is one of the reasons that some plants grow better in a particular area than not.

When these plants give or take away nutrients, they would be changing the type of nutrient composition of the soil and this is what makes crop rotation so effective.

Answer:

The phases change as the moon revolves around Earth, different portions of the moon's sunlit surface are visible from Earth.

Both South Africa and England have a similar populations. However, these countries have different population densities. Population density is how crowded the country is with people. South Africa is a much larger country in terms of its area while England has a smaller land area. If they have similar populations, but different amounts of space, one is going to have a higher population density. Since England has less space, it has a higher population density as there are more people in a smaller space. There is more land area in South Africa, so this naturally makes it less crowded.

Explanation:

Earth receives different amounts of solar energy at different latitudes, with the most at the equator and the least at the poles

Answer: this is the answer

Explanation:

The regions closest to the equator receive the most direct sunlight because the light is arriving at an angle close to 0°. As a result, a lesser area is illuminated and so there is greater solar irradiance. The regions nearest to the poles receive sunlight at more of an angle, resulting in a larger area of illumination and therefore less solar irradiance.

Colder weather can decrease plant enzyme activity. This then disrupts plant nutrient intake because plants secrete enzymes to digest surrounding materials for soil. Consequently, this can stunt growth or more severely cause them to die

Solar radiation is an example of climate’s impact on the natural character of a location. Thus option B is correct.

A long-term shifts in temperatures and weather patterns either by natural like changes in solar cycle or artificial level leads to climate change.

Artificial or man-made cause refers to burning fossil fuels which generates greenhouse gas and it act as a blanket covered over  the Earth by raising temperatures.

The two major greenhouse gases cause climate change includes carbon dioxide and methane.

These  gases comes from  gasoline use during car driving or coal for heating.

Deforestation also responsible for the release carbon dioxide where as Landfills for garbage are act as a  source of methane emissions.

Energy, transport, buildings, agriculture, industry and land are also the causative agents of climate change.

Thus option B is correct.

Factors that contribute to nation building are good governance, a united and inclusive society and a flourishing business community.

This also boosts local manufacturing and subsequently international trade with other nations thus forming meaningful ties and allies.

A government vested on good and quality educational system not only creates a sense of belonging and national unity through school curriculum, but also to develop creative and progressive minds that get to form the very fabric of the nations' financial institutes, research institutes, civil workers, engineers, future teachers, businessmen and women etc.

A society that is more equal than it was yesterday, is always one step ahead towards the goal of nation building. This is true in all aspects; a nation has to be inclusive, accommodating, diverse,...with a government with a good developmental and sustainable plan to steer the nation forward in future times to come.

barred spiral

Explanation:

The galaxy which is described as having an elongated center and spiraling arms is a Barred spiral. Thus the correct answer is A.

A galaxy is a large collection of planets, celestial bodies, gas, and particles. Gravity keeps a galaxy together. A big black hole also resides in the center of our galaxy, the Milky Way.

A spiral galaxy termed a barred spiral universe has a star-focused central bar structure. In almost two-thirds of spiral galaxies, streaks are present.

Stars no more revolve in circular orbits when a large barrel arises instead, the bar has bent the stars' orbits, which is causing them to move into more circular orbits that pass close to the center of the galaxy.

Therefore, option A Barred Spiral is the appropriate answer.
