The question is incomplete as it does not have the options which are:
Protein carrier
Lipid carrier
Porin carrier
All of the choices are correct
Answer:
Protein carrier
Explanation:
The transport of molecules through diffusion can be passive or facilitated. The facilitated diffusion in which the molecules are facilitated to cross required tow type of protein channels which are the channel proteins and the carrier proteins.
The carrier proteins are the transmembrane proteins which are specific for ions and to transport the molecules change their shape of conformation. The change in the shape is responsible for the release of ions on the other side of the membrane.
Thus, Protein carrier is correct.
The correct answers are:
Viruses are bundles of genetic material enclosed in a capsid.<span>
</span>Viruses are not living, so D is incorrect.
Viruses are much smaller than bacteria, so A is incorrect.
Answer:
D
Explanation:
those are an entirely different organelle
Well DNA is the blueprint for a person's body and tells the RNA what to do, so I guess it plays many roles... the transfer of DNA determines what a person (baby) will end up looking like once it he/she exits the womb
