d. temperature.

Answers

Answer 1
Mass/because stars are in space and space really don’t have a lot of mass.Hope I help you
Answer 2

The color of a star is determined most by its mass. Thus, option C is correct.

On which factor brightness of the star depends?

The brighter the star is, the closer it will be from the Earth. Hence, the brightness of a star depends upon the distance between the star and the Earth. The color of a star tells you how cool or hot it is. Blue colored stars are cool while red colored stars are hot (like sun).

A star is a celestial object that produces light and heat through nuclear fusion reactions in its core. Stars are made up of hot, dense gas and have their own gravity, which helps them maintain their shape. They are classified based on their temperature, size, and luminosity.

Most stars are part of a galaxy and are found in clusters called star systems. The sun is a star and is the closest star to Earth. Stars play a crucial role in the evolution of the universe and are essential for the formation and survival of planets, including Earth.

Therefore, The color of a star is determined most by its mass. Thus, option C is correct.

Explanation:

The atmosphere exerts a force on earth. Why does yhe atmosphere exert pressure on earth?

Answers

Answer:

The atmospheric molecules have energy because they have a quantifiable temperature. It vibrates and circulates, and bumps into other gas molecules. Most of them are elastic, which means that the molecules bounce off more than they stick together. The "bump" is a strength. It becomes pressure when applied over an area, such as your skin or earth's surface.

Explanation:

How much is the pressure of the atmosphere?

Pressures are determined by height (mostly by the volume of water vapor), temperature, and weather. The average air pressure, however, is 14.7 pounds per square inch, 29.92, or 1.01 to 105 paschal in regular conditions at the marine level. At 5 km altitude, atmospheric pressure is just about 50%. (about 3.1 miles).

Why is the Earth's surface under pressure so much higher? It's because the weight of all the air at that location really is measured. There's not much air around you to press down while you are high in the atmosphere. The whole atmosphere is heaped above you on the surface of the Earth. While the gas molecules are extremely light and distant, they are many!

A eukaryotic cell has 6 chromosomes, explain what you would get at the end meiosis.

Answers

Answer:

If a eukaryotic cell has 6 chromosomes, the end result after meiosis is two daughter cells with 3 chromosomes each.

Explanation:

Meiosis is the process of cell division by which sex cells or gametes are formed. It is a mechanism of reductive division, since the chromosomal charge of a eukaryotic celldiploid— is reduced by half, that is, haploid cells are obtained.

A diploid eukaryotic cell with 3 pairs (6) of chromosomes, after meiosis produces two haploid daughter cells, with 3 chromosomes each.

This process of reductional division, where the gametes are obtained, aims to ensure that when the gametes of each parent join together they form a diploid cell, the zygote.

which could describe the properties of sedimentary rock?

Answers

Answer:

Sedimentary rocks contain rounded grains in layers. The oldest layers are at the bottom and the youngest layers are at the top. Sedimentary rocks may contain fossils of animals and plants trapped in the sediments as the rock was formed.

Explanation:

Sedimentary rocks are formed by the accumulation and lithification of sediment, which can include sand, mud, and organic matter.

What are sedimentary rocks?

Sedimentary rocks are a type of rock that is formed by the accumulation and lithification of sediment, such as sand, mud, and organic matter. They often have layers, or strata, and may contain fossils and other clues about the environment in which they were formed.

They typically have the following characteristics:

Stratification: Sedimentary rocks often have distinct layers, or strata, which can indicate the environment in which they were formed and the sequence of events that occurred during their formation.
Clasts: Many sedimentary rocks contain clasts, which are pieces of other rocks or minerals that have been incorporated into the sediment. These clasts can provide information about the source materials from which the sedimentary rock was formed.
Fossils: Sedimentary rocks are often rich in fossils, which are the remains or traces of plants or animals that were preserved in the sediment. Fossils can provide information about the ancient organisms that lived in the area where the sedimentary rock formed.
Cementation: Most sedimentary rocks are held together by some type of cement, which can be a mineral such as calcite or quartz, or a chemical bond. The type of cement can affect the physical and chemical properties of the sedimentary rock.
Porosity and permeability: Many sedimentary rocks are porous and permeable, which means they have spaces between the grains and can allow fluids to pass through them. The porosity and permeability of a sedimentary rock can depend on the size, shape, and arrangement of the grains, as well as the type of cement present.
