Responda
  • temperature
  • organic
  • solvents

Questão 2

Questão
An increase in temperature results in more [blank_start]kinetic[blank_end] [blank_start]energy[blank_end]. An increase in movement results in more [blank_start]fluidity[blank_end] and permeability
Responda

Questão 3

Questão
The phospholipids [blank_start]vibrate[blank_end], causing them to get further apart. Once there are bigger gaps in the membrane, larger molecules can pass through
Responda
  • vibrate

Questão 4
