Exotoxin virulence factor is a substance that directly damages cell membranes or enters cells and changes their function.

Exotoxin- Exotoxins are a class of soluble proteins released by bacteria that enter host cells and catalyze the covalent alteration of one or more components of the host cell in order to change the physiology of the host cell. Exotoxins are produced by both Gram-positive and Gram-negative bacteria.

Bacteria- Microorganisms that are unicellular, capable of autonomous reproduction, and generally free-living are known as bacteria. In nature, bacteria are found everywhere. The foundation of all life on earth, they are architecturally basic but functionally sophisticated creatures.

Why is it difficult to avoid a tsunami?
Gelneren [198K]

Answer:

It is difficult to avoid a tsunami due to it being such a large volume of water that is capable of destroying a large amount of land.

Explanation:

However, even though it is difficult to avoid a tsunami, as they are extremely difficult to predict, there are ways where one can begin to prepare before it hits. One of the ways you can do this is getting to a higher ground far away from inland, avoiding downed power lines, and steering clear of buildings or bridges where large, heavy objects could fall during an aftershock.

Tsunamis are incredibly dangerous, since there is a great chance that if you get caught in one, you can drown. Since tsunamis have little to no warning when they arrive, it is always essential to be prepared when one strikes.

I hope this helped! :)

The human body uses a variety of organic molecules as sources of energy. In what order does the body usually access these source
love history [14]

Answer:

Explanation:

The human body stores energy through different forms. One of it is by organic food molecules that contains sugar, fat and proteins which are rich sources of energy. Whenever the body doesn’t have enough energy to pull through, it uses these reserves of energy. The molecules start a smart process because instead of releasing all the energy at one, it slowly releases little by little in a process called oxidation (for the body not to run out of energy at once).
