When we talk about the "shape" of the universe. It is its intrinsic shape, not the embedding of the universe within a larger space.

It does make sense to talk about the intrinsic shape. Properties like "curvature" can be measured from inside a shape, you don't need suppose that the universe is "in" something to talk about its shape.

Now the space of the universe is three dimensional, this creates visualisation problems. So I'm going to first talk about an imaginary 2d universe:

A 2d universe could be flat, with a curved boundary (like a disc) Or it could be flat with no boundary (an flat infinte plane). Or a 2d universe could be intrinsically curved. If it has positive curvature it could be like the surface of a ball (positive curvature, finite with no boundary) Or shaped like a bowl (positive curvature) Alternatively it could have negative curvature: it could be shaped like a "Pringles crisp" These have negative curvature (this can happen with or without a boundary). Finally there could be regions with different curvature: positive in some parts, negative in others.

The same possibilities exist for our universe: It could be flat (with or without boundary) It could be positively curved (This is intrinsic curvature and your brain can't visualise this for a 3d shape) Or it could be negatively curved (again, don't try to visualise this for a 3d shape, you can't). In the case of positive curvature, it could be finite and unbounded, but for negative curvature, it must either have an edge, or be infinite.

So mathematically these are the possibilities. What does the science say?

We can measure the curvature on large scales. Our measurements are not perfect, there is some room for error. We measure the large scale mass/energy density of the universe, since curvature is caused by gravity, and gravity is caused by mass and energy. If the mass/energy density is > 1 then space would be positively curved. We actually find that the energy density is 1.00±0.02 That is the universe is either flat, or very nearly flat.

No there are profound problems with supposing that the universe has a boundary. But there are also problems with supposing it to be infinite. Scientifically, no edge has ever been detected. So when we build models of the universe, we will generally suppose to have no edge.

Thus our "best guess" is that the universe is uncurved and infinite.

Answer:

The extinct species called Pakicétus and Indohyus may have had close evolutionary ties to humpback whales. The differences between Indohyus, Pakicetus, and Humpback whales are that Indohyus and Pakicetus both had legs and lived on land, while whales live in the ocean and have no legs. Although the embryo of a humpback whale has limbs that are dormant when it is adult, this could indicate that the animal's ancestors lived on land. Pakicetus and Indohyus are similar to humpback whales because their heads are shaped like long whale skulls. Everything is constantly changing due to evolution, the fossil record of the humpback whale is probably incomplete.

Answer:

Some plankton are known for making shells whose chemistry records the environment they live in. ... Their microscopic, mineralised plates (known as coccoliths) contain a chemical imprint of the cell, as well as the environment, and leave a different and highly variable chemical signal in the sediments preserving them.

Answer:

Lebanon

Explanation:

A country in the Middle East, touching the Mediterranean Sea.

Lebanon is a small Middle Eastern country situated on the eastern shore of the Mediterranean Sea. Hence option B is correct

It is known for its rich history, diverse culture, and beautiful landscapes. The country has a population of around 6 million people, consisting of different religious and ethnic groups, including Muslims, Christians, and Druze.

Lebanon has faced numerous political and economic challenges over the years, including civil war, political instability, and regional conflicts. In recent years, the country has been facing a severe economic crisis, with high unemployment, inflation, and a shortage of basic goods.

Despite these challenges, Lebanon remains a vibrant and resilient country, with a thriving arts and culture scene, delicious cuisine, and friendly people.

Beirut, the capital city, is known for its lively nightlife, beautiful beaches, and historical landmarks. Lebanon is also home to many UNESCO World Heritage Sites, such as the ancient city of Byblos and the ruins of the Roman city of Baalbek.

Thus option B is correct .

Answer:

The Earth, Sun, and Moon

The Earth

Earth, which is our base from which we look into space, is constantly moving. Understanding this movement is one of the most useful and important things in astronomy.

The earth orbits the sun in an elliptical orbit and the moon orbits the earth with the same kind of orbit. Looking down from the north pole, the earth spins in a counterclockwise direction on an imaginary line called its axis once every day. This accounts for the fact that the sun rises in the east and sets in the west. The earth’s axis is tilted with respect to the plane of its orbit at an angle of about 23.4 degrees. If we position ourselves high above the north pole, we would see that the earth orbits the sun in a counterclockwise motion, coming to the same position among the stars every 365.26 earth days. We would also see that the moon also orbits the earth in a counterclockwise motion. This is illustrated in the following example.

Figure 1: The directions of the orbits of the earth and moon.

The average distance from the earth to the sun, the semimajor axis of its orbit, is 149,597,890 km. This distance was not known until recently and it is called the astronomical unit or AU. The distances of the other planets to the sun are usually measured in astronomical units.

Because of the tilt of the earth, not every place on earth gets light every day. Also, some places have extremely short days.

As the earth revolves around the sun, the place where light shines the brightest changes. This motion gives us the different seasons. For instance, the poles receive less light than does the equator because of the angle that the land around the poles receive the sun’s light. When the north pole is tilted toward the sun, the northern hemisphere is presented to the sun at a greater angle than the southern hemisphere and the northern hemisphere gets warmer. When this happens, the northern hemisphere gets summer while the southern hemisphere gets winter. When the south pole is tilted toward the sun, the two seasons reverse hemispheres. This is illustrated in the following image.

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:

We nepalese people have diversified climate verification lifestyle and other variation due to cultural variation because Nepali itself is divided into 3 regions (terai,hilly and mountain).

People of different culture/ethnicity live in their particular regions such as Sherpas, Manangis,Lopas etc are inhabitant of mountain region. Rai,Limbu,Chettris etc are inhabitant of hilly and Tharus,Brahmin

Answer:

Hadley.

Explanation:

In 1735, George Hadley proposed a model of the atmospheric circulation for planet Earth and it was referred to as the Hadley cell.

Hadley cell are low-latitude overturning circulations which comprises warm, moist air that rises into the atmosphere near the equator and air sinking at roughly 30 degrees latitude.

This ultimately implies that, the Hadley cell is the continuous atmospheric convection cell in the Northern and Southern Hemisphere which have an ascending limb near the equator and a descending limb near 30 degrees latitude.

Additionally, the south-moving winds and north-moving winds connect the columns of vertical movement at low altitudes and high altitudes respectively.
