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.

What is herd immunity, and why are vaccines important for achieving herd immunity?
kap26 [50]

Answer:

Herd immunity is a form of indirect protection from infectious disease that can occur with some diseases when a sufficient percentage of a population has become immune to an infection, whether through vaccination or previous infections, thereby reducing the likelihood of infection for individuals who lack immunity.

Explanation:

Vaccines create immunity without causing illness or resulting complications. Herd immunity makes it possible to protect the population from a disease, including those who can't be vaccinated, such as newborns or those who have compromised immune systems.

lbvjy [14]

A habitat is the area where a plant or animal naturally lives and grows. You could think of habitat as the special place in a community in which a plant or animal lives.
