Is a garden salad a physical Or chemical change?
A biological process imply chemical and physical changes.
What are changes happen to the food?
Food undergoes physical, chemical, and biological changes during storage and preparation. Physical changes may include freezing, heating, or grinding. Chemical changes involve oxidation, browning, or fermentation. Biological changes occur when microbes grow and spoil the food.
Which property of life is responsible for changes seen in organisms over time?
The property of life responsible for changes seen in organisms over time is evolution. Evolution is the process by which organisms change and adapt over generations in response to environmental pressures, leading to the diversity of life we see today.
How does a stone get weathered?
A stone gets weathered through a combination of physical, chemical, and biological processes. Physical weathering occurs when rocks are broken down into smaller pieces by factors like wind, water, and temperature changes. Chemical weathering happens when the minerals in the rock react with water or gases in the atmosphere. Biological weathering involves organisms like lichens and plant roots breaking down the rock.
Are nutrients responsible for the chemical changes that break foods down into simpler forms for use by the body?
no. enzymes
How does biological evolution differ from chemical evolution?
Biological evolution is the process of changes that occur in living beings that can be passed on to their offspring. Chemical evolution is the process of changes that occur in substances. However, scientists have found that these substances have changed to form organic molecules, meaning that they have created life from nonliving substances.
What are the 3 factors that affect weathering?
The three factors that affect weathering are mechanical weathering (physical breakdown of rocks), chemical weathering (chemical changes in rocks), and biological weathering (weathering caused by living organisms).

What statement is true of enzymes?
Enzymes are biological catalysts that speed up chemical reactions in living organisms by lowering the activation energy. They are specific in their action, meaning they catalyze specific chemical reactions. Enzymes can be denatured by extreme pH or temperature changes, affecting their function.
How do enzymes in proteins facilitate chemical reactions within living organisms?
Enzymes in proteins speed up chemical reactions in living organisms by lowering the amount of energy needed for the reactions to occur. They do this by binding to specific molecules, called substrates, and helping them undergo chemical changes more efficiently. This allows biological processes to happen at a faster rate, enabling cells to function properly.

The property of life responsible for changes seen in organisms over time is evolution. Evolution is the process by which organisms change and adapt over generations in response to environmental pressures, leading to the diversity of life we see today.
Why is oxygen called the active part of air?
Oxygen is called the active part of air because it is highly reactive and essential for combustion, respiration, and many chemical reactions. It is responsible for supporting life processes and various chemical changes that occur in the atmosphere and living organisms.

Is the conversion of mulberry into silk a chemical change?
The conversion of mulberry leaves into silk is not a chemical change; rather, it is a biological process involving silkworms that digest the leaves and produce silk through their cocoons. The transformation from leaf to silk involves physical changes and biological processes, but the chemical structure of the silk proteins is produced by the silkworms from the nutrients in the mulberry leaves. Therefore, while the process involves living organisms and results in a different product, it does not involve a chemical transformation of the original material itself.
Chemical Weathering?
In chemical weathering, rocks are broken down, and their composition changes. Chemical weathering is caused by water, oxidation, carbon dioxide, organisms, and acid rain.
Organisms undergo constant chemical changes as they mainain an internal balance known as the?
Organisms maintain an internal balance known as homeostasis. This involves regulating various chemical processes to keep internal conditions stable despite changes in the external environment. Homeostasis is crucial for the survival and proper functioning of living organisms.
