Plants make their own sunscreen. The phenolic compounds in plants ( its a natural chemical) acts as a sunscreen. It absorbs UV rays. Plants also protect themselves using a protein known as UVR8 (short for UV resistance locus 8). Plants that lack UVR8 cannot induce protective sunscreens and are severely damaged by the UV present in summer sunlight.

Passage of peptides through the blood-brain barrier with colloidal polymer particles (nanoparticles). Brain Res 1995, 674 (1), 1
Sloan [31]

Numerous proteins and other substances are injected into the neurons.

  • The blood-brain barrier functions effectively to protect the brain from common infections.
  • Because of this, brain infections brought on by blood are incredibly rare. When they do occur, brain diseases are frequently severe and challenging to cure. Only a few anti-infection medicines can traverse the blood-brain barrier because antibodies are too large.

A chemoelectrical signal that can travel along cell membranes in a wave-like pattern is a(n)?
OverLord2011 [107]

A chemo electrical signal that can travel along cell membranes in a wave-like pattern is called a nerve impulse.

What is a nerve impulse?

  • A nerve impulse is an action potential generated across the plasma membrane of the neurons of our nervous system.
  • The electrical potential difference generated across the neurilemma i,e., the plasma membrane of the neurons (due to the reception of the external stimulus), is responsible for the generation of the nerve impulse.
  • Neurotransmitters, chemicals like acetylcholine, dopamine, etc., are also involved in transmitting nerve impulses across neurons.

Hence, the chemoelectrical signal that can travel along cell membranes in a wave-like pattern is a nerve impulse.
