Answer:
The Sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust called a solar nebula about 4.5 billion years ago. Most of the material was pulled toward the center to form our Sun, which accounts for 99.8% of the mass of the entire solar system.

The increase in gravitational pull, which caused the surrounding gas and dust to be pulled towards the center of the developing solar system.
What is the Solar system?As the mass of the sun increased during the formation of the solar system, several important changes occurred. One of the most significant changes was the increase in gravitational pull, which caused the surrounding gas and dust to be pulled towards the center of the developing solar system. As a result, the temperature and pressure at the center increased, eventually reaching a point where nuclear fusion began and the sun became a star.
The increase in mass also had an impact on the orbits of the planets. As the gravitational force of the sun increased, it caused the orbits of the planets to become more stable and circular, rather than elliptical or irregular. This stability allowed the planets to maintain their orbits over billions of years, contributing to the long-term stability of the solar system.
In addition, the increase in mass allowed the sun to retain more of the lighter elements, such as hydrogen and helium, which were abundant in the early solar system. This abundance of lighter elements contributed to the formation of the gas giant planets, such as Jupiter and Saturn, which have massive hydrogen and helium atmospheres.

what are 5 abiotic things in a forest that are a part of a food web? this is for science
Answer:
minerals, light, heat, rocks, water, temperature, and soil
Explanation:
Biotic factors are the living parts of the ecosystem, such as plants, animals, insects, fungi and bacteria. Abiotic factors are the non-living parts of the ecosystem, which influence the size and composition of the living parts: these are components like minerals, light, heat, rocks and water.
Answer:
Sunlight, Temperature, Wind, Water, Soil
Explanation:
You need sunlight for photosynthesis, you need temperature because if a ecosystem or forest is too cold, plants won't grow, if it's too hot, there won't be enough water. Wind because seeds would be transferred throughout. Water, obviously. Soil because nothing can grow without it!

Explanation:
What is the effect is a beam of light hits a green leaf?
When light strikes a green leaf, most of the green spectrum is reflected and most of the other colors are absorbed.
what is light?We can see light as a sort of energy. The sun provides some illumination. The other light is artificial. Man-made light is created by converting another type of energy, such as electricity, into light energy. From a source, light travels in a wavy beam to whatever it encounters. Each hue is represented by a tiny wavy beam on the beam. A light beam travelling through the air that contains all of the hues appears to be clear.
What is reflection?When a light beam strikes an object, such as tree leaves or an apple, the color of the object influences the smaller color beams inside the light beam. All color rays except green are absorbed by the green leaves. Only the green beam is reflected back, thus the leaves appear green to our eyes. Except for red, the apple absorbs all color beams. Only the red beam is reflected back, thus the apple appears red to human eyes. This is referred to as reflection.

A chimpanzee and a pine tree have very little in common. However, because they are both living things, we can be certain that they both -use the sunlight to make their own food.travel with other members of their species.are made up of one or more cells.have a skeleton which allows them to move.
Answer: C. Are made up of one or more cells
Explanation: Good luck! :D
A chimpanzee and a pine tree have very little in common because they are both living things, and made up of one or more cells that is the first and third option, as they are both living forms of nature, and while the chimp is movable, the pine tree is not.
What is the significance of the animals and plants?The significance of animals and plants is that both have unique characteristics and equal importance in nature, such as the plants' ability to produce food through the process of photosynthesis and the animals' ability to keep the system clean, such as when some animals help in plant fertilization, maintain the carbon and oxygen cycles, and so on.
Hence, a chimpanzee and a pine tree have very little in common because they are both living things, and made up of one or more cells that is the first and third option, as they are both living forms of nature, and while the chimp is movable, the pine tree is not.

Evaluate if knowing the type of the source of pollution helps make clean-up easier. Justify your opinion in 4-6 sentences and using at least 3 direct quotes from the article.
Knowing the source of pollution aids in clean-up because the nature of pollutants and how they are recycled differ, so knowing the type and amount of pollutants aids in pollution cleanup.
What is the significance of knowing the types of pollution?Knowing the source of pollution can make clean-up easier because it allows for targeted and effective removal of the pollutants as it identifies the specific source of the pollution rather than trying to address pollution throughout a wider area. It also helps in determining the most appropriate remediation technique to use, the cost of clean-up, etc.
