The local newspaper has published the passage below.

Last week, scientists released incredible images of aurora australis, known as the northern lights, as seen from the Hubble telescope. The Hubble telescope was placed in orbit in 1990 by the space shuttle and has since delivered the sharpest images we have of our planet, our galaxy, and the universe. The images delivered last week show the beautiful display of lights in the southern hemisphere. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn.

Which statement in the news passage above is inaccurate?

The aurora australis cannot be seen from space.
The Hubble telescope does not orbit our planet.
The aurora australis is known as the northern lights.

Answer the following questions with a picture only PLEASEEEEE.

1. What is the main source of energy for ecosystems?

2. What are some natural things that can disturb ecosystems?

Answers

Answer:

1.Photosynthesis is the process of converting light into energy

2.Natural events, such as wind, drought, flood, fire, or disease.

Explanation:

1.Since photosynthesis converts light into C-H bonds in organic material, photosynthesis is the most common source of energy in most habitats, and therefore carbon flow and destiny are inextricably related to energy flow.

2.Natural disasters such as wind, drought, storm, burning, or disease may cause disruption. These "natural occurrences" are often linked to human activities. Air and water emissions, as well as climate change effects such as temperature, rainfall, and ocean chemistry, are also examples of human disruptions.

How can wind and water change the materials on earth's surface? (Specifically, rocks/the geophere) ​

Answers

When mechanical and chemical weathering breaks up materials on the Earth's surface, erosion can move them to new locations. For example, wind, water or ice can create a valley by removing material. ... When layers of eroded material pile up, it's called deposition. This can create new landforms.

Answer:

Disease can reduce the size of a population quickly.

The amount of resources, such as food and water, limit how many pikas can survive.

The presence of predators limits how large the population can grow.

As the population grows, the pikas compete with each other for resources.

The amount and types of space avalible in an environment mean only a certain number of pikas can make homes.

Write a paragraph on why our food has to be digested.

Paragraph has to have full explanation and complete sentences.

Thank you for your time! ^﹏^

Answers

Digestion is important because your body needs nutrients from food and drink to work properly and stay healthy. Proteins, fats, carbohydrates, vitamins link, minerals link, and water are nutrients. The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. When we eat such things as bread, meat, and vegetables, they are not in a form that the body can use as nourishment. Our food and drink must be changed into smaller molecules of nutrients before they can be absorbed into the blood and carried to cells throughout the body. Digestion is the process by which food and drink are broken down into their smallest parts so that the body can use them to build and nourish cells and to provide energy.

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Write a paragraph on why food needs to be digested. :)

Please hurry I need it.

Answers

Answer: You die if no digest

Explanation:

Food needs to be digested because your body can't contain large stuff whole, so it has to be converted into a smaller amount. For Instance, if you were to eat a entire turkey then your body would just explode I guess if you wouldn't digest it. Also, without digesting food you can't enter new food into your body. Therefore, this is why food needs to be digested.

Im sorry if my answer is two short but you can expand or take the idea of it.

Food needs to be digested into tiny particles in order for your body to absorb its nutrients and convert it to energy.
