Resumo de Recurso

Questão 1

Questão
The two things that break down membranes are [blank_start]temperature[blank_end] and [blank_start]organic[blank_end] [blank_start]solvents[blank_end]
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
  • kinetic
  • energy
  • fluidity

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

Questão

[blank_start]Ethanol[blank_end] is an organic solvent
Responda
  • Ethanol
  • Glucose
  • Water

Questão 6

Questão
