Answer 1

Answer:

Physical properties of a substance can include color, temperature, and mass. These are physical properties because they can be measured without changing a substance's chemical identity. Chemical properties of a substance can include flammability, acidity, and reactivity. These are chemical properties because they can be measured only by changing a substance's chemical identity.

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.

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 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.

Write a paragraph (5-8 complete sentences) answering the prompt"How does the availability of resources in ecosystems impact ecosystems?"

Answers

5-8 Sentences on: "How Does The Availability Of Resources In Ecosystems Impact Ecosystems?"

Changing out natural resources in our environment can affect the whole entire ecosystem.  Ecosystems can change throughout time but the change may or may not affect the ecosystems.  But according to research, if the change is too fast the whole ecosystem can be destroyed.  An imbalanced or damaged ecosystem can lead to problems.  Certain resources play an important role such as sunlight and water, we need resources to survive and can also help living creatures.  These resources impact animals, plants, and insects/bugs.

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.

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.
