What does not contribute to physical weathering?
Chemical reactions do not contribute to physical weathering. Physical weathering refers to the breakdown of rocks into smaller pieces without any change in their chemical composition.
What of these does not cause physical weathering?
Chemical weathering does not cause physical weathering. Chemical weathering refers to the breakdown of rocks through chemical reactions, while physical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition.
What is something same about chemical and physical weathering?
Both chemical and physical weathering processes break down rocks into smaller pieces. While physical weathering involves the physical breakdown of rocks without changing their chemical composition, chemical weathering involves the transformation of rocks through chemical reactions with substances like water or acids.
Are physical and chemical weathering the same?
No, physical weathering involves the breakdown of rocks into smaller pieces through physical processes like temperature changes and abrasion, while chemical weathering involves the breakdown of rocks through chemical reactions with substances like water and acids.
What are physical and chemical weathering?
Physical weathering is the breakdown of rocks into smaller pieces without changing their chemical composition, caused by factors like temperature changes, ice, and plant roots. Chemical weathering involves a chemical alteration of rocks, changing their composition through processes like oxidation, dissolution, and hydrolysis, and is influenced by factors like water, oxygen, and acids. Both processes work together to break down and transform rocks over time.
Is digest a chemical or physical property?
Digestion is a chemical process that breaks down food particles into smaller molecules through the action of enzymes. It involves the breakdown of complex molecules into simpler ones through chemical reactions.
What type of chemical energy needs to make glycolysis happen?
Glycolysis primarily relies on the chemical energy stored in glucose molecules. During glycolysis, the process breaks down glucose into smaller molecules like pyruvate, generating ATP (adenosine triphosphate) as a source of energy for the cell. This initial investment of chemical energy from glucose helps drive the subsequent steps in glycolysis.
What state of metabolism degrades monomers such as glucose into smaller molecules?
Degradation and some oxidation to smaller molecules.
Is digesting a candy bar a physical or a chemical process?
Digesting a candy bar involves both physical and chemical processes. Physical processes include chewing and breaking down the food into smaller pieces, while chemical processes involve enzymes breaking down the food into smaller molecules that can be absorbed by the body.
What must happen to glucose moleculs before respiration begins?
the glucose molecules must break down into two smaller molecules
The smaller molecules from which cellulose is made are?
The smaller molecules from which cellulose is made are glucose monomers. Glucose molecules are linked together by beta-1,4 glycosidic bonds to form long chains of cellulose. These chains then associate to form the strong and rigid structure of cellulose fibers.
Look at the word equation below: Glucose + Fructose ---> Sucrose + WaterWhich phrase describes the chemical reaction taking place?
This chemical reaction is an example of a condensation reaction, where two smaller molecules (glucose and fructose) combine to form a larger molecule (sucrose) with the elimination of a smaller molecule (water).
What is a physical and chemical change that take place in the digestion of food?
A physical change that occurs during digestion is the mechanical breakdown of food into smaller pieces through chewing and churning in the stomach. A chemical change that takes place is the breakdown of macromolecules like proteins, carbohydrates, and fats into simpler molecules like amino acids, glucose, and fatty acids through the action of enzymes.
Starch consists of smaller units called?
Glucose. Starch is a polymer made of glucose monomers.
Is mixing sugar and water physical or chemical?
Physical. The water breaks up the crystals of sugar into individual molecules, but you still have sugar and water. The sugar is just in smaller clumps.
What type of energy is stored in food molecules?
Chemical potential energy
Compared to the ingested food molecules the end product molecules of digestion are usually?
Smaller and simpler molecules that can be absorbed by the body, such as glucose, amino acids, and fatty acids.
