What else can I help you with?
A substance that moves across a cell membrane without using the cell's energy tends to move?
from an area of low concentration to an area of high concentration (if it is water) the opposite if it is a solid
What is the assive process that is movement of a substance from an area of high to low concentration?
a passive process is any process that occurs without an input of energy. the process of a substance moving from a high area of concentration to an area of low concentration in order to obtain equilibrium is the process of diffusion, this requires no energy input therefore it is a passive process. Diffusion is a property of atoms. atoms move randomly but overall the net movement of atoms will always be to spread away from a high area of concentration. the reason for this can be explained by considering a perfume bottle. once opened the gas in a perfume bottle has the ability to escape, the reason the perfume leaves the bottle (this is just a theory) is because there are only so many ways that the atoms in the perfume bottle can be arranged but there is trillions of more ways that the atoms can be arranged outside of the bottle so probability tends towards the perfume escaping the bottle and spreading out in the room.
How are diffusion and active transport different?
There are two types of diffusion. Facilitated and non facilitated. Diffusion occurs when there is a concentration gradient. That is, when an area has more concentration than the other area. Diffusion is used to transfer particles from one place to another. Active transport is used to transfer particles, usually occurring against a concentration gradient. Active transport requires energy to occur however, diffusion does not. There are two types of diffusion. Facilitated and non facilitated. Diffusion occurs when there is a concentration gradient. That is, when an area has more concentration than the other area. Diffusion is used to transfer particles from one place to another. Active transport is used to transfer particles when there is no concentration gradient. Active transport requires energy to occur however, diffusion does not.
Is Diffusion always from areas of greater to areas of lesser concentration?
Yes, diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. This process occurs in order to reach equilibrium, where the concentration of particles is equal throughout the system.
A factor that tends to cause species to change is a?
change in environmental conditions, such as temperature, rainfall, or availability of resources. This can lead to changes in behavior, physical characteristics, or gene frequencies within a population, ultimately driving evolutionary adaptations.
A substance that moves across a cell membrane without using the cell's energy tends to move?
from an area of low concentration to an area of high concentration (if it is water) the opposite if it is a solid
What is a substance that moves across a cell membrane without using the cells energy tends to move?
away from the area where it is more concentrated
What is an abhesive?
An abhesive substance is the opposite of an adhesive substance - one which tends to be slippery, such as Teflon.
What are surfactants?
A substance that tends to reduce the surface tension of a liquid in which it is dissolved.
As the temperature of a substance increases its volume tends to increasein temperature?
Due of Charles' Law
What is propollent?
A propellent refers to any substance that is capable or tends to move or propel something.
When does someone is crave a chemical substance?
Craving tends to occur in those individuals who have developed physical and/or psychological dependence on a potentially addictive substance.
General direction in which something tends to moves?
Nowhere unless propelled and then in the direction it is propelled.
What is active voice to passive voice and vice versa?
Active voice: "John attended school." Passive voice: "The school was attended by John." Passive voice: "Jane was helped by John." Active voice: "John helped Jane." In active voice, the subject of the sentence usually comes first and is doing the action to something else. In passive voice, the predicate is being acted upon by the subject. Passive voice tends to be harder to read , and it tends to use more words. So for the most part, you should avoid using passive voice.
What do understand by reducing agent?
A substance that tends to bring about reduction by being oxidised and losing electrons
What does it mean when someone is passive?
Being passive means someone tends to avoid confrontation or taking action, often letting others make decisions for them. They may not assert themselves or express their thoughts and feelings, leading to a lack of involvement or initiative in situations.
What substance has a specific gravity less that water?
One substance with a specific gravity less than water is oil. This is why oil tends to float on top of water.
