What would happen to your body's absorption rate of the intestines if villi had no microvilli?
If the villi of the intestines had no microvilli, the absorption rate of the intestines would be significantly reduced. Microvilli are tiny finger-like projections on the surface of the villi that increase the surface area for absorption. Without microvilli, there would be less surface area available for nutrients to be absorbed into the bloodstream, leading to a decrease in absorption efficiency.
What do two or more substances form when they come together without forming a new substance?
These substances form a mixture.
What is the movement of substances without the use of energy by the cell?
Passive transport.
What is true about most enzyme assisted reactions?
They occur more quickly than reactions without enzymes.They occur more quickly than reactions without enzymes.
How do enzymes act as catalysts in cellular respiration?
Enzymes are catalysts, substances which help to change other substances without being permanetley changed themselves.

How would you design a cell membrane that would allow you to move more material through it faster without taking more space?
The answer is Microvilli!
What substances combine without a chemical reaction?
These substances are called reactants.
Are there Substances without covalent bond?
Ionic and metallic substances both do not have covalent bonds!
What is it called when substances move past the membrane without using energy?
Passive transport is when substances move past the membrane without using any energy.
What is a characteristic of pure substances that can be observed without changing it into another substances?
lame people going wild
What is combustible substance?
Combustible substance : Substances that burn easily or catch fire easily are called combustible substances. Paper, clothes, wood, LPG are all combustible substances. Without these substances, a fire cannot be started.
Properties that depend on the substances reaction with other substances?
Chemical properties are properties that depend on the substances reactions with other substances. Physical properties can be observed without changing the composition of the matter.
What is it called when substances move past the membrane without using any energy?
Passive transport is when substances move past the membrane without using any energy.
What are substances that change the rate of a chemical reaction without themselves being changed?
Those substances are called, "Catalysts".
What do two or more substances form when they come together without forming a new substance?
These substances form a mixture.
What is an absorption nebula?
An absorption nebula is a dark nebula, which absorbs all incident radiation without reemission.
