How can bacteria survive vaccines?
Answer.
Toxoids are chemically inactivated toxins from bacteria like Clostridium tetani or Corynebacterium diphtheria. The infection with these bacteria itself does not cause the illness, but rather the exotoxins released from the bacteria. Accordingly, vaccination with toxoids leads to an antibody production against the toxins that neutralize the proper toxin protecting the body against a range of important diseases (Marvaud et al., 1998; Collier, 1975).

Answer:
This looks like an earthquake
Explanation:
There doesn’t seem to be very much water present in the image which would be the cause for the rest of them
Hope this helps
Answer:
Earthquake
Explanation:
First off I wouldn't say landslide because if it was a landslide in more than likely would have cracked the concrete on the floor that the people are standing on and there would be more of a mess than what is show in the picture. Next I wouldn't say tsunami depending on how frequent this disaster was, if it was a tsunami more than likely most of that rubbish would have been soaked with water in other things that were in the water as well and I wouldn't say flood either because once again nothing is soaked with water with in that picture not even the concrete that the people are standing on so I say that the most reasonable answer would be earthquake due to them being know for destroying buildings alot.

Explanation:
what organisms are being affected by pollution how or why/why not?
Answer:
Most marine animals
Explanation:
Most of your plastic trash ends up in the ocean. It is dumped by companies who don't know what to do with it. Seabirds are constantly eating the tiniest of plastics called microplastics, which fill the birds stomach. The bird does not feel hungry, so it doesnt eat and starves to death. Sea turtles are constantly choking on plastic, because when it floats in the water, it looks like their food: jellyfish. Sea otters pelts are unable to be waterproofed due to oils in the water, which neutralizes the waterproof oils in their fur. Not just in the ocean. CO2 emissions increase the amount of CO2 that stays in the atmosphere, which dissolves in the ocean and increases its acidity. This does a variety of things, to killing coral reefs, deforming shellfish, and outright poisoning fish. Increased CO2 builds up the greenhouse gasses around the planet, and increases the heat that bounce back to earth, thus warming the planet. This results in melting the ice of the north pole, where methane gas is trapped in the ice, thus releasing that methane to the atmosphere, and increasing ocean acidification.
