Answers

Answer 1

1. A main sequence star is any star that is fusing hydrogen in its core and has a stable balance of outward pressure from core nuclear fusion and gravitational forces pushing inward. An example is our sun

2. A giant star is any star having a relatively large radius for its mass and temperature

3. Supergiant stars form out of massive main-sequence stars that have run out of hydrogen in their cores.

4. When the pressure drops low enough in a massive star, gravity suddenly takes over and the star collapses in just seconds.

5. Super novas are so powerful they could create new atomic nuclei

I hope this helps:)

Can cornstarch disintegrate in fire or an open flame?

Answers

In an open flame because it can not only catch on fire extremely easily but also cause an explosive

Corn starch, like wood, consists of a carbohydrate complex, which is why it burns – but it will only ignite when it is dispersed in air. While it's packed in the container or in a pile on the counter it will not burst into flames due to insufficient oxygen.

What do they show about the male or female puffer fish that helps them find a good mate and make strong, healthy offspring?

Answers

The white-spotted pufferfish (Torquigener albomaculosus) is known for its unique and complex courtship display which involves creating large, geometric circles in the sand. These circles are constructed in an effort to attract females for copulation. Males must maintain their circles in order to attract a mate. A female will evaluate the structure and choose to mate with the males after evaluation and completion of other mating behaviors.

can someone please help me with this?

Answers

Answer:

1. Main sequence stars have different masses. The common characteristic they have is their source of energy. They burn fuel in their core through the process of fusing hydrogen atoms into helium.

2. Supergiants are among the most massive and most luminous stars. Supergiant stars occupy the top region of the Hertzsprung–Russell diagram with absolute visual magnitudes between about −3 and −8. The temperature range of supergiant stars spans from about 3,400 K to over 20,000 K.

3. Supergiants develop when massive main-sequence stars run out of hydrogen in their cores.

4. a supernova occur When the pressure drops low enough in a massive star, gravity suddenly takes over and the star collapses in just seconds. This collapse produces the explosion.

Explain at least one observation you can make about the political borders and the language borders shown on the maps.
Be sure to name the country and describe how its political border is affected by language or a physical feature, such as bodies of water, mountains, or desert.
Use the physical map with the labeled nations to help you identify a nation.

Answers

Answer:

A boundary is a real or imaginary line that separates two things. In geography, boundaries separate different regions of the Earth.The most obvious type of boundary is a physical boundary. A physical boundary is a naturally occurring barrier between two areas. Rivers, mountain ranges, oceans, and deserts can all serve as physical boundaries. Many times, political boundaries between countries or states form along physical boundaries. For example, the boundary between France and Spain follows the peaks of the Pyrenees Mountains, while the Alps separate France from Italy.

The Strait of Gibraltar is the boundary between southwestern Europe and northwestern Africa. This narrow waterway between the Atlantic Ocean and the Mediterranean Sea is an important political, economic, and social boundary between the continents.

Rivers are common boundaries between nations, states, and smaller political units such as counties. The Rio Grande forms a large part of the boundary between Mexico and the United States. The Mississippi Riveris the defining boundary between many of the states it winds through, including Iowa and Illinois, Arkansas and Tennessee, and Louisiana and Mississippi.

What is an ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answers

Answer:

Because the ionic compound must be electrically neutral, it must have the same number of positive and negative charges. Two aluminum ions, each with a charge of 3+, would give us six positive charges, and three oxide ions, each with a charge of 2−, would give us six negative charges.
