Answer:
Facilitated diffusion
Explanation:
Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient.
Facilitated diffusion is a passive transport process because they only depend on electrochemical gradients, so they do not need any energy to occur.
It turns out that many materials can be solid at a higher temperature if the pressure is also higher. so even though it is hotter in the inner core the pressure in the core is also higher and you can have a solid iron nickel instead of liquid
Answer: 1. a change in an individual's body in response to changes in environmental conditions
Explanation:
An adaptation can be defined as any alteration or change that occurs in the structure and function of the organism that results due to natural selection. An adaptation generally occurs when the organism is exposed to an unfavorable environment.
The adaptation makes an organism better suited to survive in an unfavorable environment.
The changes in the environment favor the changes in the body of living individuals.
