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.
A type of cell death in which the cell uses specialized cellular machinery to kill itself
Answer:
Yes. Due to the magma in the mantle, the tectonic plates in the upper crust of the earth move because of a process called *convection. The heat from the magma causes the tectonic plates to move at a very very slow rate
*An example of this is when you're cooking food in a pan. The food is getting hotter because the heat rising from the stove heats the pan.
In simpler terms: Stove ~~ Pan --> hot food
*There is no direct contact between the stove and the pan which is a defining feature of convection.
