How does active transport differ from the process of diffusion across a membrane?
Active transport requires energy and moves molecules against their concentration gradient, from an area of low concentration to high concentration. Diffusion, on the other hand, is a passive process where molecules move from an area of high concentration to low concentration without requiring energy.
Water moves into phloem by?
Water moves into phloem primarily through the process of osmosis, where it travels from areas of high water concentration to low water concentration. This movement helps create the pressure that drives the flow of nutrients and other substances through the phloem tissue.
What is the difference between facilitated diffusion with the help of a carrier protein and active transport with the help of the transport protein?
Facilitated diffusion is a type of passive transport in which a substance moves across the cell membrane from high to low concentration. In this situation, the substance moves with the concentration gradient, and with the help of carrier molecules, it is able to make it's way across the membrane smoothly and without the expense of energy. Active transport, on the other hand, is the movement of a substance across the cell membrane from low to high concentration, making the transport a bit more difficult and calling for the use of energy. Transport proteins recognize the substance and allow it to cross through the membrane.
The presence of which kind of molecules determines the concentration of other substance in the body?
Water
What is the difference between a solvent and concentration?
A solvent is a substance capable of dissolving other substances, while concentration refers to the amount of a substance (solute) present in a given volume of solvent. Solvent plays a role in determining the concentration of a solution as it affects how much solute can dissolve.
What determines in which direction carbon dioxide and oxygen will diffuse in the lungs and tissues?
The direction of diffusion for carbon dioxide and oxygen in the lungs and tissues is determined by their respective concentration gradients. In the lungs, carbon dioxide diffuses out of the blood into the alveoli where its concentration is lower, while oxygen diffuses into the blood from the alveoli where its concentration is higher. In the tissues, oxygen diffuses from the blood into the cells where its concentration is lower, and carbon dioxide diffuses from the cells into the blood where its concentration is higher.
Water moves into phloem by?
Water moves into phloem primarily through the process of osmosis, where it travels from areas of high water concentration to low water concentration. This movement helps create the pressure that drives the flow of nutrients and other substances through the phloem tissue.
What does titration measure?
Titration is a laboratory method used to determine the concentration of a solution by reacting it with a solution of known concentration. It is commonly used to measure the concentration of acids and bases, as well as other substances in solution.
What is the purpose of titration?
The purpose of titration is to determine the unknown concentration of a substance in a solution by reacting it with a known concentration of another substance. This allows for precise measurements of the concentration of a specific component in a solution.
What is the only substance that can carry out osmosis?
Water is the only substance that can carry out osmosis. It moves across a semipermeable membrane from an area of higher concentration to an area of lower concentration in order to equalize solute concentration on both sides.
What is the difference between facilitated diffusion with the help of carrier protein and active transport with the help of a transport protein?
Facilitated diffusion is a type of passive transport in which a substance moves across the cell membrane from high to low concentration. In this situation, the substance moves with the concentration gradient, and with the help of carrier molecules, it is able to make it's way across the membrane smoothly and without the expense of energy. Active transport, on the other hand, is the movement of a substance across the cell membrane from low to high concentration, making the transport a bit more difficult and calling for the use of energy.

The movement of water from an high concentration to an area of low concentration is called?
The movement of WATER from a high concentration area to a area of low concentration is called osmosis, but the the movement of MOLECULES from a high concentration area to an area of low concentration (like perfume when you spray from a high place) causes it to diffuse.
The presence of which kind of molecules determines the concentration of other substance in the body?
Water
Which is correct regarding diffusion?
It is a passive process in which molecules move from a region of higher concentration to a region of lower concentration
