What is the active ingredient in dry ice?
The active ingredient in dry ice is solid carbon dioxide (CO2). It sublimates directly from a solid to a gas at a temperature of -78.5 degrees Celsius.
What is the carbon footprint of an active volcano?
The exact carbon footprint of an active volcano can vary greatly depending on its size, frequency of eruptions, and the amount of carbon dioxide emitted during eruptions. However, volcanoes are considered significant natural sources of carbon dioxide and other greenhouse gases, contributing to the Earth's carbon cycle.
What is internal respiration controlled by?
Internal respiration is primarily controlled by the partial pressures of oxygen and carbon dioxide in the tissues, as well as the metabolic demands of the cells. The process involves the diffusion of oxygen from the blood into the cells and the release of carbon dioxide from the cells into the blood. Additionally, factors such as pH levels and temperature can influence the efficiency of internal respiration. Overall, it is a passive process driven by concentration gradients rather than active regulation.
HOW substance get transported in unicelluar organism?
In unicellular organisms, substances are primarily transported through processes like diffusion, osmosis, and active transport. Diffusion allows small molecules, such as oxygen and carbon dioxide, to move across the cell membrane from areas of higher concentration to lower concentration. Osmosis specifically refers to the movement of water across the membrane. Active transport requires energy to move substances against their concentration gradient, ensuring that essential nutrients are absorbed and waste products are expelled efficiently.
What substance is correctly paired to the way it crosses the plasma membrane?
Water crosses via osmosis. glucose via diffusion. Carbon dioxide needs assistance to pass through the membrane so it requires active transport.
What type of transport is carbon dioxide passive or active?
Carbon dioxide transport is passive because it moves across cell membranes by simple diffusion, down its concentration gradient. However, in the blood, most carbon dioxide is carried in the form of bicarbonate ions, which is facilitated by specific enzymes and transport proteins.
Oxygen and carbon dioxide are exchanged in the lungs and through all call membrane an active transport b diffusion c filtration d osmosis?
Oxygen and carbon dioxide are exchanged in the lungs through diffusion. Oxygen moves from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli, driven by differences in their concentration gradients. This process does not involve active transport, filtration, or osmosis.
What conditions does yeast need to be active and make carbon dioxide gas?
Yeast needs warmth, moisture and some form of sugar to be active and make carbon dioxide gas.
Why does carbon dioxide moves into red blood cells by diffusion rather than by active transport?
Do you mean why does carbon dioxide diffuse out of the cells into the bloodstream? Diffusion is the movement of particles from a region of high concentration to a region of low concentration. Carbon dioxide is present in your body cells at a high concentration because the cells are making it. The process which makes carbon dioxide in cells is respiration. This is the release of energy from food. Carbon dioxide is a waste product of respiration. The carbon dioxide molecules diffuse into the blood because there is a lower concentration in the than in the cells. This is because the blood is always moving, so the carbon dioxide is carried away and does not build up. The difference in concentration between the cells and the blood keeps carbon dioxide diffusing in the correct direction.

Are osmotically active substances simple diffusion or active transport?
simple diffusion.
What are two sources of carbon dioxide in air?
Carbon dioxide is the waste product of the process of respiration in plants and animals and it is also released into the atmosphere by active volcanoes.The burning of coal and wood
What is the active carburizing gas in pack carburizing?
either carbon monoxide or carbon dioxide, im still trying to figure that one out :)
