Answer: D. Eating breakfast and then going for a run.

Explanation:

Eating breakfast is a chemical change and running is a mechanical change.

Based on evidence from Sim, when two substances were combined they did not change into different substances.

Here the word Sim is used to describe the process simulation. Simulation is defined as when two substances combined they do not change into different substances.

They just combine together and form a new substance.

Let us understand it as the first substance is liquid and the second substance is solid then when we combine both of them they form a new mixture but do not change their property.

The mixture is still liquid but it also has some properties of solid substance.

The substances did not change into different substances.

Based on the information provided in the question, there is no evidence or indication of any chemical reaction or change in the substances when they were combined in the cup. The question does not mention any observations or effects that would suggest a chemical transformation.

If there were a chemical reaction or change, it would typically be accompanied by observable signs such as color change, gas production, temperature change, or formation of a precipitate. However, since the question does not provide any evidence or observations of such changes, we can conclude that the substances did not undergo any chemical transformation when combined.

It is important to note that without additional information or details about the substances and their behavior, it is not possible to make definitive conclusions. However, based on the given information, the most reasonable conclusion is that the substances remained unchanged when combined in the cup.

Explanation:

Answer: Solid state of matter

Explanation: Minerals have atoms that are tightly packed together and cannot move freely. This is a characteristic feature of solid matter where the atoms are tightly packed and they cannot move freely, has less space between them. Thus are rigid. The solid state is the most dense state of matter.

Answer:

D. There are more than 100 naturally occurring elements that make up all matter.

Explanation:

All matter is made up of elements, which are substances that cannot be broken down into simpler substances by chemical means. There are more than 100 naturally occurring elements, each with its own unique properties and characteristics. These elements combine to form compounds, which are substances made up of two or more elements that are chemically combined in a specific ratio. For example, water is a compound made up of two hydrogen atoms and one oxygen atom. Atoms can bond with each other in various ways to form compounds, but they do not always bond to achieve a stable neutron-proton ratio. The stability of an atom or compound depends on a variety of factors, including the arrangement of its electrons and the nature of the chemical bonds it forms with other atoms.

Answer:

D. There are more than 100 naturally occurring elements that make up all matter.

Mostly decaying organisms are needed to present in marine mud to form fossil fuels.

Explanation: When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed. Over millions of years, the peat became covered with sand, clay and other minerals and the peat is converted into layers of sedimentary rocks. After a long time, different type of fossil fuels are formed.

Radio telescopes convert radio waves (analog signals) to electrical (digital) signals for analysis because radio telescopes are devices used to capture radio light waves, bring it to focus, overdraw it and use the data for processing and analysis. These radio light waves, that are raw analog signals, are converted into digital signals to create and distinguish delicate details in the universe.

Answer:

When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.
