You didn't give any answer choices (i'm answering this through research and what i already know)
the first is fossilized dung, and that's not generally gastropod shells. A carbon film would be something thin, seeing as it's a film, and gastropods aren't that. A gastrolith is a stone swallowed by an animal to help with digestion, and that's also not a gastropod.
<span>Gastropod fossils may be molds, but usually aren't. Still, they can be. It's a better answer than; film or stomach stones.</span>
Specific chemicals are bound by carrier proteins and transferred on one side of the membrane. The conformational changes they go through next enable the molecule to cross the membrane and exit on the other side.
How carrier protein facilitate the diffusion?
When a molecule diffuses, it usually moves from a high concentration location to a low concentration area until the concentration is the same everywhere in the space.
Contrary to channel proteins, another form of membrane transport protein that is less selective in the molecules it transports, carriers are proteins that move a particular material through intracellular compartments, into the extracellular fluid, or across cells. Carrier proteins are found in lipid bilayer cell structures such cell membranes, mitochondria, and chloroplasts, just like other membrane transport proteins.
Therefore, carrier proteins can facilitate the diffusion of glucose or other substances into the cell.

Trauma Glasgow 7 is caused by failure to recognize and control the amount of haemorrhage. Immediate priority which nurse takes is to manage large volume of blood loss. Assessment of airway stability and patency should be performed and airway management intuited should be there as needed unless the patient is in cardiac.
Primary survey is the initial management and assessment of trauma patient. The primary purpose of the pivotal study is to treat actual and detect life threats and prevent complication from the injury. The time the patient arrives at the emergency department, full non-invasive monitoring should be applied to the patient.
The primary survey which is taken to the trauma patient include ABCDE
Airway. It is to check for any airway obstruction.
Breathing. Check for haemothorax.
Circulation. Check for circulation of blood.
Disability.
